Speech Transcript - Wayland: The future of Linux graphics is here

0:00:09	that
0:00:11	excellent okay right i did usual so i'm about but i what the intel and
0:00:15	the audience that working away then
0:00:18	see in some of looking to commit log since the think the first meet was
0:00:21	in that if it december twenty eleven
0:00:23	and i was the fix something thank you okay
0:00:26	so i would not for a while the course toolkit and i composed a bug
0:00:30	fixing features
0:00:33	so you know i think we are what they help often to stop conversation with
0:00:37	this but what when it is a just a paper away of a lot of
0:00:41	challenges around quality what people mean when they say weighted right so and you know
0:00:47	i think they precise lights a
0:00:50	the represents a weighted is a pretty cool winds communicate with the composed and when
0:00:54	you know when we about clients with them application
0:00:58	and you know about component so we kind of
0:01:02	describing something this guy hey content there's applications
0:01:05	well it together and aggregates in percent on the screen and go back and for
0:01:09	direct input was that applications for the they can be like what so you know
0:01:14	good example is menus name selling not the all the stuff and so we're gonna
0:01:18	blend those aspects together
0:01:21	so wait and strictly is the particle like education
0:01:25	and it comprise the you know we may not
0:01:28	the presentation of those windows contents and the with the contents in red and we
0:01:34	used to motive a buffet represent the contents of the wind of the winter
0:01:39	we also need to be able to take input from the this at the lower
0:01:42	levels of this no and it's alright that awards each individual application you know so
0:01:47	that we can you can use it can control that computer and then you know
0:01:52	there are aspects of things about like in terms of the it's a process communication
0:01:57	old copy and paste right control and there is a recall things that all caps
0:02:02	inside or whatever
0:02:05	and we have a lovely saying but every frame is about that i and we
0:02:10	know what we trying to this one think we promote weight and
0:02:14	what you know what we mean by that and how we achieve
0:02:18	this is a more but you know having so you can have kind of
0:02:22	glitch free were sizing that you know they can posters not gonna show any contents
0:02:26	by mobile application the gamification isn't very happy that i rented that one i printed
0:02:32	out that exactly on what i want to use it to see right and there
0:02:37	you know the mechanism doing that is that we have an a frame aggressive you
0:02:41	can tell the one can be told by the importance the where and what lay
0:02:46	off to be sure has been show so that why knows of the users doing
0:02:50	what they are
0:02:53	similarly we got the and event to say when the posters no longer show like
0:02:57	that
0:02:57	and that is the release event and i said hey you can reuse it about
0:03:00	that you can create you do whatever you like
0:03:04	and in order to be able to ensure or sort state changes that we go
0:03:08	through and the particle or result we have an explicit commitment
0:03:13	the say i want to change but just a on this surface and so this
0:03:17	is the terminology that's the used to represent the window the buffalo is the contents
0:03:23	the services window itself
0:03:26	and you know the state for that's a transaction be you know part very suspect
0:03:31	firstly you are hey can i have this but to the surface
0:03:35	and then you okay and then you need say well you know i'd change this
0:03:38	aspect amuses me say the damage there so
0:03:42	that's a you all you know gonna huge
0:03:44	turn what we all do you have and it is i'll a blinking cursor and
0:03:48	you know you that we won
0:03:51	optimization perspective pasta one we have hey i'm to be jewel this one aspect or
0:03:56	the terminal whatever application is doing the damage we give a region say this is
0:04:00	the area that's czech and in the composite second okay collect and actually read the
0:04:05	whole of the screen i can just change this one aspect
0:04:09	similar is another optimization strategy you can have the ability to say this is near
0:04:13	pay area for so
0:04:15	so you remind might have alpha transparent buff
0:04:20	but have nice shadows around my application
0:04:23	but
0:04:24	maybe most of applications actually have taken do it is just the chatter that so
0:04:31	as an optimisation you to compose the word without knowing the base there is a
0:04:36	hey we have to zipping up gonna paying clients and to the director the you
0:04:41	get the correct landing of all the different parts together with potential transparent can anticipate
0:04:47	they can just get a just one
0:04:50	that one
0:04:51	in the region is will similar idea that that's a i've got my
0:04:55	application and it doesn't once again have to months drop shot is because the decorations
0:05:01	and wait and a lot one class i'd the not drawn by the composer
0:05:05	so we want to have that shattered we don't want to we have to be
0:05:10	really it might not it might be they teacher reminds you get close to you
0:05:13	might wanna be able to resize the window and shut it we don't want you
0:05:17	want to be able to react so we can adjust it is it in prevention
0:05:21	and all there's things are captured in this transaction a few of the state changes
0:05:27	that so you know when you can me
0:05:30	what will become of the what can you react to what you said when you
0:05:34	meet this allows you to get we consistent a behaviour all of the applications of
0:05:39	the plunge we need to make how old reacting to what's all signal gonna get
0:05:44	a point state where you know you haven't got the of cake we can synchronise
0:05:47	of what you're expecting it to be you can really ensure got good pay
0:05:52	and you do the other aspect of every frame of the crippled but which previous
0:05:56	eyes so
0:05:58	you know finding in inside way why initiated and all the direct
0:06:04	so when you hit the to choose the resize the with the you resize grip
0:06:11	you tell you tell the able to pay you know they stop size i mean
0:06:15	and then of the can
0:06:17	it's a grab and then send a stream of configure bands to you to say
0:06:20	hey you know so you decided to be decided to do so
0:06:23	but you know that one reactor configure red highlights you can we can reach or
0:06:28	ignore and say determine size groups attaching as it's about so the bar or one
0:06:34	have to determine the side window so
0:06:38	there is no
0:06:40	posted terms the size a but actually didn't apply to read rule so you to
0:06:43	get like an area where have really exposed to sell a lever draw so you
0:06:48	can get that kind of which pretty resizing
0:06:50	that's a lot of all
0:06:51	affection all right and the mechanism to achieve that
0:06:56	and then the next aspect is the input that are like to direct you to
0:07:01	the clients
0:07:03	but you expect we have simple people mouse touch is a first pass it and
0:07:08	borrow from beginning
0:07:10	you inspired by the accident to put to touch aspects and
0:07:16	the composite all takes input
0:07:19	first is that from the devices
0:07:21	it separately and then send it a lot
0:07:25	any it is responsible for directing in the
0:07:28	and
0:07:30	there's no ability for any want to any take any particular collapse
0:07:34	they often place a base grab them grab the because portal taken you profits about
0:07:38	situation
0:07:40	but there there's no to
0:07:41	textile it global grab so you know one of the things that was talked about
0:07:46	in terms of is of security that i think atlanta mention with the about the
0:07:51	typically the isolation of the plot in talked about having a this place ever that
0:07:55	helps with the isolation of the different applications and you know through the input we
0:07:59	you know input direction where and able to achieve
0:08:03	and then
0:08:05	that's a lazily ancillary stuff like the selection the dragon drop and that kind of
0:08:09	it's positive based
0:08:12	so maybe can kind of efficient transfer the contents between
0:08:16	well okay should based on my so we've got that sort of flexibility to try
0:08:21	and work out how the client should be talking to each other
0:08:24	and you know the selection is really coupled in the by the you can imagine
0:08:29	right
0:08:30	and situation where in some kind of a multi seat environment where we can make
0:08:34	it big
0:08:36	table that has got flat screen on and its multiple people using the computer the
0:08:39	same time because they label and like to associate with that each person can have
0:08:46	maintained and playful of the you can get some privacy have user experience aspects
0:08:52	unified and then you know how to still single pebbles you don't have a confusion
0:08:56	with the like primary secondary whiteboard you have one
0:09:01	and then this one aspect this is probably in the is the shell and space
0:09:05	and it catches
0:09:07	some of the aspects that you would need to build a you a you know
0:09:12	a full user experience well at some more to be multiple you
0:09:16	you know that ability to say hey you make myself is full screen and these
0:09:20	captured in the shell so
0:09:23	i'm of the full screen of the ability to say
0:09:26	i would you know to i mean how one should
0:09:29	make that application great difference maybe showing of it
0:09:33	and you video is that any company and used one for and second can actually
0:09:38	tops
0:09:39	people's to when you get full screen to say going to drive them out and
0:09:43	instead of frame right and then the close to will actually change mode on the
0:09:47	outputs to satisfy the one that we're not doing any what mister
0:09:53	can opportunity for playstation you know or so you can awesome full screen to scale
0:09:58	it doesn't fatal to censor a book like a lot of that sure
0:10:02	already mentioned however sizing works do also divinity to for the quite not able to
0:10:08	start with
0:10:09	so once don't have any idea about the absolute position
0:10:13	well now we know what out there one
0:10:16	all the dimensions about all the they don't know if they're in the top left
0:10:19	ankle all about right
0:10:21	so i'm
0:10:22	they cut is the river than impressed because if i start writing
0:10:28	what in plan around white part of all i wanna push my mouse down on
0:10:31	thought of all and the client has planted in several at a i want start
0:10:35	moving
0:10:37	the clients and the requested of course the you start meeting please like important it
0:10:41	takes
0:10:42	as i didn't expect improvement to grab centre leave event like to the one to
0:10:47	say hey neuromotor of the focus and then just all smoothing it around you know
0:10:52	when you be moved and you returns a stopping move because you and you can
0:10:56	never enter that
0:10:58	so
0:10:59	there is no i want to have just which is
0:11:02	different we have on eleven and that's created charges when it comes will to talk
0:11:06	about one of it
0:11:08	and then the shelters also catches aspects of roles that whether it's at the top
0:11:13	level application window or pop up or transient i'm the difference between pop transient the
0:11:18	pop up have some right maintenance the comport to take we to say that you
0:11:23	would when you click outside old just based window a well tell you can dismiss
0:11:27	the fall and
0:11:29	and now uses a man majestically you expected but when but as i mentioned is
0:11:34	in this is kind of quite a
0:11:36	limited script maybe not suitable putting a communication from belief ledge their stuff application to
0:11:42	a fully fledged desktop environment maybe we need to look at this proposal to start
0:11:46	on this on the next one my colleagues rough i'll who is working on this
0:11:51	idea of a next you shell maybe capture some of bigger aspects that we need
0:11:56	all of how about want to communicate with a more well the top invite
0:12:03	so in one point two we had a couple cool new features
0:12:07	we got because of subset
0:12:09	you're going to open yourself and if methods at a our next cycle to be
0:12:14	just like to go for his talk just think about in quite good detail and
0:12:18	with also gained a staple at i always that the that means that if you're
0:12:22	open to both so you can rely on some stability of that if you are
0:12:26	inside the others like we become somewhere help you will go composed
0:12:33	so
0:12:35	like
0:12:37	so it sounds that this is what you know what is this is this is
0:12:40	there is if it's the be been a you know i was thinking long for
0:12:42	a long time they thought in the meeting some of the things i wanted to
0:12:46	get through a not a not on a project
0:12:48	but subsets is a lot is it's a good analogy and it to what you
0:12:52	can do with X where you can take a window and every parent the inside
0:12:56	not winter
0:12:57	so that kind of gets used in bunch applications enlightenment starcube that you crime is
0:13:03	this all the time one does it different
0:13:05	browser process but also you know freedom is a in a okay it's of the
0:13:10	stand aspect but it's
0:13:13	way because next is pretty horrible pretty racy so on the we have the subsets
0:13:18	this article that was developed by packet from lab or
0:13:22	and many others and you know operational less and this is a really good solution
0:13:28	it allows you to create off the composite to give us all sub composes the
0:13:33	and then you can get a sets the saves my main surface and then i
0:13:36	quite another service to create subsets men without subsurface you can position it in it
0:13:42	within another aspect on money surface by their it up of course the other subsurface
0:13:46	is or what positioning in X and Y
0:13:49	and this very valuable when you come to implement plastic U K for instance where
0:13:54	people to separate libraries the both created surfaces i don't expecting to use it this
0:13:59	is and therefore and kind of are designed to be talking a formal to each
0:14:04	other wanna coming combined together into a single application
0:14:08	another really good example of where you might wanna use subsidise body but we have
0:14:12	a G stream about he with great inspiration
0:14:16	but you know i've got mine my accelerated to be a play that which is
0:14:19	all expecting to take it buff ago in and decode straight into this buffer and
0:14:24	hardware you know do whatever colour space conversion or whatever things needs to the ticket
0:14:29	and then a bit out ready to use in for willing to compose
0:14:33	questions a what most to compose
0:14:36	but we actually want to build a window a
0:14:39	i mean if that slide to having substances we actually have to kind of read
0:14:43	that data back and then landed in ourselves
0:14:46	this of services allow you that all the do the blending for so that we
0:14:50	don't have and then perhaps you can make some of the all wet do some
0:14:54	of that work for
0:14:57	so it's of the very valuable recently came in one point two
0:15:01	implemented also like this is what was done by a christmas
0:15:06	this is really important was when we stop talking about that screen
0:15:10	when we wanna be don't just use a standard could people when they may need
0:15:14	to talk with regard so there's a package sitting in G T K but there
0:15:17	are to integrate the
0:15:20	the support it okay and that
0:15:24	but she you can use now that's one of the clients on the and it
0:15:27	so this two aspects to implement as vertical the client uses the talk to the
0:15:32	post to which school the text vertical and it sort of is a problem i
0:15:36	think i personally at an impulse in article it's a the last at for that
0:15:43	but the a left to right and you can you know something that is you
0:15:47	want to care about the surrounding text is very sure contact and the decline content
0:15:51	let by to the to the in the implement
0:15:54	and then at the particle for the internet that don't both to
0:15:58	to actually some controlling unique at about how much
0:16:02	and we have a couple of people for you
0:16:06	that sounds one hears the sample one this inside a what
0:16:10	is just little test a and it's replication
0:16:13	there's a really good agreeable one important aspect all recent work try make great and
0:16:19	more ready right now
0:16:23	so you know
0:16:24	what we also doing in terms of the particle changes going forward
0:16:29	you know point about one important aspect of the games and it's and catch quite
0:16:33	heavily in the in the web standards now
0:16:37	this is
0:16:39	hope positioning and negotiation as i mentioned that we don't have any concept of where
0:16:45	you are absolutely in the screen
0:16:47	so detache
0:16:49	expects you have to get the full dimensions of the output find it where is
0:16:53	absolutely and then position the rearrangement of pop that in some aspect of it so
0:16:57	that it would be visible you
0:16:59	so you'd if you get ready to the bottom of your window it will hopefully
0:17:03	out of your screen popping up so that
0:17:07	so that what i posted have to that i haven't been up kinder to G
0:17:11	T K adding that big hurdles run into
0:17:15	but the way i my proposed by the solution that is to say if i
0:17:19	was to pop up a surface that this dimension at this location relative to where
0:17:24	our car and
0:17:26	what would be the visible rectangle from that you can kind of the way the
0:17:29	you be falling of the left hand side of the right hand side looked all
0:17:33	will bottom of man you can kind of position yourself so unique and she that
0:17:38	and i at the sub so expert at which apparently
0:17:43	not in the weighting corporate will would be we have been proven you know through
0:17:48	that agent
0:17:49	and that for you in and the article is good all make be promoted being
0:17:54	in school where the project
0:17:59	so you know this is what we really want to about name integration
0:18:06	and so i already a couple to created are gonna a the just explain how
0:18:12	but if moving fall that's we have inside name integration here save
0:18:17	we have the we had this old to you want to
0:18:21	maybe minimum well it but what well we went have as well
0:18:25	we just have one but
0:18:28	will only the i want hot about it you know we have huge guy and
0:18:34	we did U K uses S H and buffet type and this is the memory
0:18:37	map file solution
0:18:39	this of a really readily available those requiring hardware acceleration are we used car and
0:18:43	it's image surface to drawer into that image that this and it's a gem of
0:18:50	a of your
0:18:51	over the
0:18:52	in a class a little couple we use
0:18:58	you G L U G L it got which is make you i that is
0:19:02	so
0:19:03	flight it to me said in the music one slide aspect of it hidden inside
0:19:08	the E G L platform communique we may extension to the composer to sets up
0:19:13	to tell the how it combines the information but you know the that sort prior
0:19:18	you can have different drivers you can have your work because of their particular like
0:19:22	an indication this is the accelerated
0:19:25	how this using you know level about the management all like that
0:19:30	and global i have a problem but both have a pi are handling
0:19:37	one thought
0:19:38	and both so
0:19:41	and then you know the that can maybe you inside martin and i'm shell to
0:19:45	create name shell that is a way of
0:19:49	and specs all we have inside problem part to do that is that this ability
0:19:55	to create a force acts on
0:19:58	represents the contents
0:19:59	all hey wait and stuff
0:20:04	so we can actually than a free the user experience we want in matter and
0:20:09	then show
0:20:10	so
0:20:11	is it all screenshot to give educators the i suggested i think it was so
0:20:16	what you could carry running on way on western here this is the people west
0:20:20	and user experience the test with the best of show you know and it looks
0:20:25	pretty good one thing you know you think about that so kind of how to
0:20:29	because the
0:20:30	but decorations landed they landed in this like a thank you them ultimately the setting
0:20:36	in and urging that they can sell abroad for a long time myself and christine
0:20:40	and it's it really what how them and now it's not this it would be
0:20:43	a way to think
0:20:46	that you know into the G T K to improvements recent middle should be in
0:20:49	addition all the hiding you know i will once with a high dpi what i
0:20:53	likes it
0:20:56	and you know the also we have a school that you bring of the you
0:21:01	know what things the way back and the G T K and if you think
0:21:05	it's just
0:21:06	it's existence simply doesn't then but i think the real progressive stuff recently in this
0:21:10	like a will be making really good progress
0:21:13	and it sounded you know the kind of gaps that remain and made you want
0:21:18	that we would like make the is a the copy paste that is implementation of
0:21:24	copy pasted i put in a while back that
0:21:28	a copy the coolest model and we have a copy all think opencal source file
0:21:33	evolve in such as uk that when if you compile await and actually wait and
0:21:38	you're crippled well i would be replaced with this instantiation of the object that happens
0:21:42	you know it's not very good dot typing it looks just like that
0:21:49	abortion that's really what you wanna call but when next you have ever in one
0:21:53	aspect or you kind of migration strategy
0:21:56	and then the other major thing for you to build a perspective is a place
0:22:00	so there were some there are some asking so we'll kind of
0:22:05	i think what well there are few hacks where we actually started you position we
0:22:10	take the positions of the way it says that we're ways zeros or
0:22:14	and the many popups that actually works one a big challenges
0:22:18	you can carry menu position found
0:22:21	which is a and but it is like and use applications if you if we
0:22:27	are
0:22:28	exposes global cool so it's not level that's one of the few places in the
0:22:33	just anywhere global coordinates projects but so some of can pick a pop up and
0:22:38	we have to position it absolutely on the screen
0:22:41	so what did the chance that
0:22:44	flats
0:22:46	but works pretty well
0:22:48	and
0:22:49	it's just man a few random applications that on the well that's applications they well
0:22:56	i think that's that'd be either you
0:23:00	nobody many channels and particle the results you know if you centering all the major
0:23:07	issues around that have been resolved one thing that was really affecting a real ability
0:23:12	to before with the migration of gnome clients
0:23:17	run again
0:23:18	wait and of course post aside my name shell walls
0:23:23	got you can never n-classes the K is used
0:23:28	right so you can buy cheese because you know as a as the way that
0:23:32	they used
0:23:33	or tickets just to and
0:23:36	that's it came with the whole thing about where than only made of possible
0:23:41	recently following the availability of
0:23:44	subsets as well subset
0:23:48	and so actually i and one thing i was working on by recently was making
0:23:52	a what
0:23:53	so i can't it then i
0:23:55	strategy to K which i think
0:23:57	and the most of the
0:24:10	you know well
0:24:19	and this is obsolete events running on the west end
0:24:30	i have to we still might well do you can these two screens
0:24:37	so it once real application right name terminal
0:24:41	it's just
0:24:43	visible and then that's just do
0:24:47	it's company a name right
0:24:53	which one clear on this one
0:24:56	there again so that we've got have to
0:24:59	working inside
0:25:01	a T K application
0:25:03	using custody today
0:25:06	and
0:25:08	in a bit it you get input the works looking at all
0:25:13	that's right
0:25:16	what would just will still again we
0:25:22	well understanding for one
0:25:26	okay so we've got we've got you know
0:25:29	a T calcutta stage here and we got
0:25:33	i we can just make use the making curtains will not in G T K
0:25:39	to
0:25:43	so this use is
0:25:45	this use the subsurface so we have one
0:25:48	the G T K O
0:25:50	like the points mini crash
0:25:52	we have a
0:25:55	we that message that generate event
0:25:59	i'm not really the label pointer okay like generation event that's quite cool pathfinder what
0:26:04	that does
0:26:07	no this one generated be let the your it with any like to okay fine
0:26:13	i think about
0:26:14	so you very we think about in this work you can see as it's all
0:26:18	let you record this we will and brought up to do you guys and the
0:26:22	and the we slash audience hey question mark project but that you to games about
0:26:28	the as well that some nice at a projects the west and
0:26:33	to make this work so but they are you have a subset gettysburg that the
0:26:37	you that may not at the middle top level service with them an application right
0:26:41	and then we create it we all know the close because of sub all that
0:26:45	and then we get lisa let me create new surface on credit subsystem that out
0:26:51	that in susceptible of and some of the and we part that service in two
0:26:55	parts so you only go with what we have to add in first ad api
0:26:59	too cluttered to save make it simple what support are working on a on a
0:27:03	foreign that this
0:27:05	surround trying to create sounds that's this to save event handling
0:27:09	so we don't have multiple things do
0:27:11	all i wanna be able chargeable that
0:27:16	because we got these two stacks you might be expected they are the anything talking
0:27:21	to the
0:27:22	waylon well that we need to make sure they use the same can connections because
0:27:26	the because otherwise they would have different object id and then you would be upset
0:27:30	you work combine is to
0:27:32	rate a single location and the composite so was kind of assuming that there would
0:27:37	be only a single inputs
0:27:40	however sorry single to input device brazil's i like handle we cannot use the handle
0:27:46	the also have for the object that it inside thought writes
0:27:52	and small but also have a question to make it but what it does that
0:27:57	indeed what they're still a few problems and ask you can see apple so this
0:28:01	T
0:28:02	you could be
0:28:03	who
0:28:05	i mean
0:28:08	so i with my present diamonds my presentation was like on
0:28:16	so what you have said about events working on
0:28:20	what's the
0:28:26	people's we never thing so basic this where this is this is the major what
0:28:31	their stock point for us enabling all the games right and
0:28:36	achieved run again
0:28:37	weighted
0:28:39	you know and then the next aspect or
0:28:43	all the you know it or the name inspiration side
0:28:46	i think i think to in pretty good shape the game riga progress
0:28:50	you know and we have a goal is listed on the on this one as
0:28:54	well i'm up especially in the person and was
0:28:58	it's
0:28:59	i would make about how we wanna try and get name show when it was
0:29:02	to run against
0:29:04	no three ten that's available one meeting you will recall that being people i think
0:29:10	disenchanted around them in the next few days
0:29:14	you have discussions with anyone is interested in weight and for about intel red hat
0:29:20	and all the absolute organisations and community are interested
0:29:23	to try and kind of
0:29:26	make some progress on that on what how we can cheap
0:29:30	what
0:29:32	you know many applications the only testing in fixing
0:29:36	there are
0:29:39	of interesting problems if the applications and you know we need to work at
0:29:44	so we just need to make sure we can the not applications
0:29:48	make a direct express or expect you have the cost air display to be and
0:29:53	G T K excellent right so use go through and find a patient next but
0:30:00	i think but
0:30:02	the state talk at the coming stands nights a week and i'm going you can
0:30:06	i'm some of money so i think that we should be applicable purpose that and
0:30:12	i think over the next not we should have seen many patches come into the
0:30:17	application make work on different what make more like elsewhere
0:30:24	that is the end of mine
0:30:26	well
0:30:27	are there any questions and we do have a plan to go into the panel
0:30:30	discussion
0:30:32	and off this so maybe people something that's we don't we processing
0:30:38	so i can you demonstrate that we can free perfect resizing or do you
0:30:46	right i the
0:31:01	for that if an application
0:31:03	a lady events
0:31:06	that's right but even so it's always so lucky when the results
0:31:14	well i think i mean i think it's a it's a futuristic about twelve hundred
0:31:18	on my laptop which is so you know i think from the
0:31:25	i mean
0:31:26	no you problems even with you know some nice applications so i call this a
0:31:57	sorry well
0:32:00	in this host like is the window manager is that some point that does it
0:32:06	just fit into it or you have to rewrite it completely no i'm talking about
0:32:10	the but environments like the ecstasy so on
0:32:15	so
0:32:17	in the button and the way to model the can the composer and within manager
0:32:23	all there's no separation like might expect so that
0:32:27	dean than the admit of these windows that i'm doing inside less than a which
0:32:31	is this a reference
0:32:33	and like positive that we have
0:32:37	that is being we runway and mention like i didn't decided its shell plucking
0:32:41	and the different shells this that's top shelf that different idea but there is no
0:32:47	side by communication on the extra communication between something that doing the job all the
0:32:52	comp of like you could have the X of the whole thing and window manager
0:32:56	so you to avoid so about it ahead of you know in matter on the
0:33:00	traditional X able to desktop we have a one five projects have excess of all
0:33:04	of that fixed and
0:33:06	fine so we it's just a single and it's all
0:33:18	i
0:33:19	that doesn't go back to the resizing issue rub if you could try moving the
0:33:23	window we can point out that when you move the window you can see there's
0:33:26	no leg at all between the cursor position and window position
0:33:30	so if you if you compare the two moving on the X you can see
0:33:32	how the excuse open the case has ribbon that the window any case of a
0:33:36	been supportive we have to reinvent an entire page and scale it well one thing
0:33:40	that we could do is we could fix the cursor position to the corner of
0:33:44	the application window so that it looks as if we never lack and that that's
0:33:48	but just one of it
0:33:51	a options we have once we combine with this place of a composite we can
0:33:54	actually control where the cursor goals these cases
0:34:00	me
0:34:02	what we have a team and the information small and
0:34:06	in a in a T V so
0:34:09	you can see i'm i think i'm kind of in this i mean the border
0:34:12	as anybody in chat a one we need to do is we need actually happy
0:34:16	we did some you need to just be able to chat a so that we
0:34:19	can kind of the resize would be a still usable
0:34:23	the entity much deeper channel you want to be able to resize the whole each
0:34:26	other down here
0:34:28	that's whether you
0:34:32	sure what's do with G D M and system composite stuff
0:34:37	unlike looking in this post use which are in the can stuff
0:34:42	i you at one of panel on that's a really good question let's say that
0:34:47	i think that some of the other participants on that we have on a much
0:34:50	but like
0:34:53	the good question which is
0:34:57	the richer countries and great very for a how to management to west
0:35:02	so and using you had that might and using no control centre changing the colour
0:35:07	i think running the nonetheless
0:35:23	well
0:35:31	do we have something like
0:35:34	it the X settings are similar and there's some of the properties that like them
0:35:39	sitting demons that like sixty P R i am the doubleclick wearing then
0:35:46	so there are there are nice i think that all
0:35:50	there are you know there are exciting that occur that in the past but it's
0:35:54	and
0:35:55	something like people p-value over to they of the to the class on the
0:36:02	but
0:36:04	you know each client
0:36:07	everyone should use D car but i don't know i mean it
0:36:12	i don't know that
0:36:14	it this is like saying vacation different have different decorations a different all
0:36:25	sure
0:36:27	word or you do wanna
0:36:29	but to have no one is also
0:36:36	okay
0:36:58	that's not quite the same thing you know you know do you get the millimetre
0:37:02	size
0:37:04	what do you do reports
0:37:16	my question was about plotted you to carry dentists obsessive implementation is that in G
0:37:22	T K and use it here's and it's not that G T K A back
0:37:25	and
0:37:27	the thanks a question for you get the costs it's okay implementation using subsets is
0:37:32	just and that's okay
0:37:36	and you know what like
0:37:39	a little
0:37:43	okay well
0:37:57	i
0:38:00	would you like
0:38:08	no
0:38:14	who
0:38:19	so it's only have occasion a team actually make any changes that we can do
0:38:23	that this talk applications the come in at the door i didn't even compile them
0:38:27	so the running with the runtime detection back and it's give is indication reduce the
0:38:32	need do some work
0:38:33	to
0:38:36	we begin right
0:38:42	like minor
0:38:45	i see the
0:38:48	okay
0:38:57	to
0:39:03	the innocent this is they this is this is the any changes that have to
0:39:06	make that okay
0:39:08	so to make it something
0:39:11	you waited so we just kind of
0:39:13	we greatest can we try to the surface all the costs of this
0:39:18	we get the surface from jic you tie
0:39:21	the G T K for the window reset the
0:39:25	so if is that we can post a recreation the composite on
0:39:29	trough the and then we create a sub composite it so
0:39:35	so
0:39:39	was my first version the second version my i think it's cool here
0:39:45	it gets the application X and Y
0:39:52	now i'm sure it's not i think it when we are correctly to resizing the
0:39:56	window but it's just initial
0:39:59	this is idea to realise function of the
0:40:02	okay with you
0:40:19	i'm so i this is just the this is finishes it off see i make
0:40:23	progress is the air you know we are moving parts with that us five this
0:40:28	is you know making good progress
0:40:32	question
0:40:34	so i'm not sure if you haven't talked about this already but my question is
0:40:39	what if someone position becomes the unresponsive it freezes can i still move the window
0:40:45	can i still the resize the window can i still talk to close the window
0:40:49	with the dialogue like force great but it as it is now what happens
0:40:55	i can kind of that
0:40:59	or
0:41:01	okay
0:41:03	controls D and
0:41:07	it's right by my point again sorry
0:41:14	right so i well i per cent six talk to
0:41:17	the internal here ornamental process
0:41:22	so the ping pong particle that the line and you are able to set the
0:41:27	pauses in the paying requirement at one thousand and upon by
0:41:30	i hope that i mean that they are processes on the spot so any because
0:41:35	that you changes be cussed to a little
0:41:39	is the area we could have you why this it unresponsive you really good and
0:41:45	if i have to the you can you can read it but if you to
0:41:48	compose the driven
0:41:50	moving here
0:41:51	problem one on one click but if i then
0:41:57	and then unit
0:42:06	we have a you know as you can see that when i hear we change
0:42:08	the cursor when we start thing and that's that is one thing that when you
0:42:13	move the pointer in this
0:42:15	step is to comply want get and prevent the one on setting up whatever "'cause"
0:42:19	one and i don't like to meetings like beans or wait in the way lucas
0:42:23	of the ladies and those things from the experts
0:42:28	okay
0:42:36	one more question
0:42:46	that's a any discussion was how is my vision proposal different approaching absolute coordinates
0:42:55	well
0:42:58	mm
0:43:04	he be the code to be neat and they pop up this negotiation based on
0:43:11	the i want to do this particular area that in does take into consideration any
0:43:15	so that this transformations
0:43:18	so i
0:43:20	with people in the
0:43:22	spinning that's it
0:43:25	super right click
0:43:28	so i can i can do this by myself it might myself is could be
0:43:31	rotated like that you know you don't want to remember pop up menu as you
0:43:35	know but example this don't have any pop up menus
0:43:38	if i bring up is
0:43:44	i would say that well
0:43:47	a roomful menu we wanna problem and you to be in the right place right
0:43:51	so if you if you have to step to X Y coordinates make a lot
0:43:55	doesn't know about this transplant
0:43:58	so you really shouldn't be doing that absolute coordinates to be a particular
0:44:06	okay
0:44:08	okay
0:44:12	the single that change
0:44:15	we might we might it might change this would be ubm to movies in but
0:44:18	i haven't that
0:44:20	it's not you what can transform okay
0:44:23	posted it buddy
0:44:29	or
0:44:30	well you know why just like all to a
0:44:33	i
