| smspillaz | duflu: next-day-pong | 01:34 |
|---|---|---|
| MCR1 | haha | 01:35 |
| duflu | smspillaz: Huh? | 01:35 |
| smspillaz | duflu: you pinged me at 5pm yesterday | 01:35 |
| duflu | smspillaz: Whatever it was I solved it... :/ | 01:36 |
| duflu | Can't remember | 01:36 |
| smspillaz | it was probably about the xsync stuff | 01:36 |
| duflu | No, don't think so | 01:36 |
| duflu | smspillaz: Hmm, actually it was about how to reproduce anything slower than 60 FPS, so yeah | 01:36 |
| duflu | Clearly I need a slower machine with nvidia | 01:37 |
| duflu | And I did try a dirt-cheap nvidia card too | 01:37 |
| smspillaz | duflu: I found the cause | 01:37 |
| duflu | smspillaz: Yeah looks like it might be related to the LLVMpipe window movement regression I reported too | 01:38 |
| smspillaz | I've noted it in bug 1027211 | 01:38 |
| ubot5 | Launchpad bug 1027211 in compiz (Ubuntu) "[nvidia] Moving or resizing windows freezes and stutters on nvidia (especially if some other window is redrawing)." [High,In progress] https://launchpad.net/bugs/1027211 | 01:38 |
| smspillaz | just working on something that could work now | 01:38 |
| duflu | But I have been thinking about reverting the damage repair method to be asynchronous again | 01:38 |
| duflu | smspillaz: I know, just saying it might apply more to the other bug :) | 01:38 |
| smspillaz | duflu: well, I think you might be able to get away with removing the XSync in damage repair | 01:38 |
| smspillaz | unless there's a race condition I'm not aware of | 01:39 |
| duflu | smspillaz: The XDamage functions are synchronous too. They should not need another XSync | 01:39 |
| smspillaz | duflu: yeah | 01:39 |
| smspillaz | duflu: interesting though, removing that got me about 10fps | 01:39 |
| smspillaz | duflu: can you double check by breaking in _XReply in XDamageSubtractRegion ? | 01:40 |
| duflu | smspillaz: But weirdly at the time I swear I got damage artefacts without it and had a good reason.. ? | 01:40 |
| smspillaz | duflu: yeah I remember you saying something about that | 01:40 |
| duflu | smspillaz: Later... I am hours away from being able to look at code. It's the start of my day. Not sure where yours lies | 01:40 |
| duflu | lays? | 01:40 |
| smspillaz | duflu: I have a meeting at 12 today and thats it | 01:41 |
| * smspillaz somehow to conned into doing rails | 01:41 | |
| smspillaz | *somehow got | 01:41 |
| duflu | smspillaz: rails? | 01:41 |
| smspillaz | duflu: ruby on rails | 01:41 |
| duflu | smspillaz: That's what I thought. OK | 01:41 |
| smspillaz | duflu: I'm doing this internship / volunteer position thingy with http://bighelpmob.org/ | 01:42 |
| duflu | smspillaz: Cos you're generous... and bored :) | 01:43 |
| smspillaz | and I get sucked into things | 01:43 |
| smspillaz | and seem to be procrastinating getting that startup off the ground | 01:43 |
| duflu | smspillaz: I was criticising your complaint about holidays and then realized when I was at your age, I worked through the summer holiday too | 01:43 |
| smspillaz | workahol ;-) | 01:43 |
| duflu | 5/7ths pure alcohol | 01:44 |
| smspillaz | XD | 01:44 |
| duflu | Oops, 2/7ths | 01:44 |
| smspillaz | I see what you did there | 01:44 |
| smspillaz | 5/7ths also works | 01:45 |
| smspillaz | as to 7/7ths | 01:45 |
| smspillaz | *as does | 01:45 |
| smspillaz | duflu: anyways, what I was thinking of for the nvidia slowdown was to restore parts of the code that didn't immediately send geometry updates to the server but make it opt-in instead of opt-out | 01:46 |
| duflu | smspillaz: If that really is the main problem then we should stop. Sit on your hands. Sending geometry updates to the server is something we should do. | 01:46 |
| smspillaz | duflu: ah, sorry, delay sending those updates | 01:47 |
| duflu | Hence I was going to analyse the damage repair and again glib source priorities | 01:47 |
| smspillaz | duflu: it should be possible to do it right - this is what mutter is doing AFAICT | 01:47 |
| duflu | smspillaz: Yes but we have a feedback problem, probably. --> https://bugs.launchpad.net/compiz/+bug/1025586 | 01:47 |
| ubot5 | Launchpad bug 1025586 in compiz (Ubuntu) "[0.9.8 r3110 regression] [LLVMpipe] Dragging windows around is much slower with compiz 0.9.8 than 0.9.7 (using LLVMpipe)" [High,Triaged] | 01:47 |
| smspillaz | duflu: not really, its literally just that the nvidia driver can't handle ConfigureWindow requests at the same time as doing opengl | 01:48 |
| smspillaz | nfi why | 01:48 |
| smspillaz | (erm, can't handle a continuous stream of them) | 01:49 |
| duflu | smspillaz: Yeah that's a big issue, but maybe it's hard to distinguish multiple problems while the above bug exists | 01:49 |
| smspillaz | duflu: okay, sorry I stand corrected, mutter does do that | 01:51 |
| smspillaz | must be something else we do around that area | 01:51 |
| * duflu afk | 01:51 | |
| fginther | bschaefer, I updated https://code.launchpad.net/~fginther/nux/add-code-coverage/+merge/138007 per your comments | 02:05 |
| smspillaz | duflu: ok, I have a workable solution to this problem, will have it up by tomorrow \o/ | 03:31 |
| duflu | smspillaz: I'm still in analysis and will test your proposals against both bugs | 03:34 |
| smspillaz | duflu: the problem is a quasi-feedback-loop | 03:34 |
| duflu | As always, good software development is 80% of the time thinking and only 20% typing. Anything more than that is dangerous | 03:35 |
| smspillaz | duflu: nvidia chokes on XConfigureWindow, as expected, however because it chokes we get more time to send it more XConfigureWindow requests | 03:36 |
| smspillaz | which makes it choke even more | 03:36 |
| smspillaz | I'm part of the way done with it | 03:36 |
| duflu | smspillaz: So that sounds like the LLVMpipe bug. Please propose against that | 03:37 |
| duflu | And maybe nvidia too. | 03:37 |
| smspillaz | duflu: nah its just nvidia | 03:38 |
| smspillaz | duflu: unless llvmpipe has exactly the same problems | 03:40 |

| bobweaver | was unity2d dropped because no one wanted to port 4.X to 5 and qml2 ? because nokia stoped for qml1.0 support ? | 19:39 |
| bobweaver | I want a real reason why as llvm is not all that great. or was it $ on canonical ? | 19:40 |
| bobweaver | I am asking this after watching Rick spencers thing on ubuntu on air | 19:41 |
| bregma | bobweaver, I believe it was dropped because it required a completely duplicate effort to maintain two identical desktops with two codebases | 19:43 |
| bregma | no sane entity would want to do that | 19:44 |
| bobweaver | bregma, so in other words no moe money for qt devs ? | 19:44 |
| bobweaver | and no need for 2 things that do one thing | 19:44 |
| bregma | I don't know why one was chosen over the other, but I understand it was a difficult decision | 19:44 |
| bobweaver | well I guess that the next question is just that ^^ | 19:44 |
| bregma | and most of the Qt devs were rolled into the since Unity project, so it wasn;t a money thing | 19:45 |
| bobweaver | why nux c++ stuff because it was house ? | 19:45 |
| bregma | *single Unity project | 19:45 |
| bregma | I really have no inside information on what motivated the final decision | 19:45 |
| bobweaver | I mean it makes sense but the only fact is that llvm is not working all that well for me | 19:46 |
| bregma | it's still a work in progress | 19:46 |
| bobweaver | I am not trying to fight for 2d here I just want a clear understanding of why I should learn nux and why I should learn welll learn more c++ | 19:47 |
| bregma | Qt is also C++ | 19:47 |
| bobweaver | if unity 3d was used which it is I am sure that there is a smarrter person then me that can tell me why these things are best to learn or why what thye work on is what they love | 19:48 |
| bobweaver | bregma, I know that they are libs | 19:48 |
| bobweaver | but thanks :) | 19:48 |
| bobweaver | Like I could list of the top of my head why I love to use qml right , I am sure that there are people in this channel that can also do that with say compiz nux ect | 19:49 |
| * bobweaver is trying to get motivated ;? | 19:50 | |
| bobweaver | Like Nux will be able to do X in the future that we could not see X doing in the future , kinda | 19:52 |
| bregma | Nux can do crazy things with shader (GPU) programming that Qt requires direct OpenGL programming on a canvas for | 19:56 |
| bregma | doing the same in QML requires extending QML using Qt and Open | 19:56 |
| bregma | OpenGL | 19:56 |
| bobweaver | what is wrong with opengl (es) rendering ? | 19:57 |
| bobweaver | thanks for this bregma I really like this subject | 19:57 |
| bobweaver | so you are talking about libdeclaritive shaders from qt community ? | 19:58 |
| bobweaver | I guess what I do not understand about what you said ^^ is the "QML requires extending QML using Qt and Open" what do you mean by "Open" ? | 19:59 |
| bregma | OpenGL | 20:00 |
| bobweaver | TBH I have only been using qml and programming for 1.5 years | 20:00 |
| bobweaver | well qml 6 months maybe year | 20:00 |
| mhall119 | bobweaver: I think the big difference is that Nux is a toolkit build on OpenGL, where at Qt has to go through abstraction layers before it gets to OpenGL | 20:01 |
| mhall119 | which makes Qt portable, but also heavier | 20:01 |
| bobweaver | so I guess that I have to figure out why the shader system is different then the one used in Nux to see the great things that it offers | 20:02 |
| bobweaver | atp right now I am just learning how to layer things in nux | 20:02 |
| mhall119 | I wouldn't expect "great things" in the way of features | 20:02 |
| mhall119 | Nux is, after all, a very new toolkit | 20:02 |
| mhall119 | but it should be fast and light and work well anywhere OpenGL support exists | 20:03 |
| bobweaver | mhall119, something that I always thought about you is that you are easy to talk with about these types of things even if I am new and dont understand some things | 20:03 |
| bobweaver | bregma, is also awesome j/s | 20:04 |
| bobweaver | so how does compiz and all this play togeather with Opengl | 20:05 |
| mhall119 | bobweaver: It's easy for me to talk about things in a non-technical way, when I know so very little about the technical side of it :) | 20:05 |
| bobweaver | like can or how are there any limits on compiz and open gl | 20:05 |
| bobweaver | If there are * | 20:06 |
| mhall119 | Compiz itself is kind of limited by X, and being a window manager for X | 20:06 |
| mhall119 | Unity has had to work around some of those problems with things like Bamf | 20:06 |
| mhall119 | since X doesn't have any concept of "this window belongs to this application" | 20:06 |
| bobweaver | mhall119, I think that I need to go through more of the old code esp the src/pirvate-unity-2d stuff so I can understand more of how the libs where all being drawn together. ATM I have bo clue where I would even start on that with 3d. besides just looking at #import's and then reading there libs | 20:09 |
| bobweaver | maybe there is a way to break the chain so to say | 20:09 |
| bobweaver | after I learn that maybe I will have a much better understanding of how unity as a whole is geared , and not just reading dash/* ect for unity 3d as I see that it is importing libs I just do not know what some of these libs do Or even how I can use them | 20:11 |
| bobweaver | I think that that right there is super impoant if I want to learn how to design anything in unity 3d. But I could be wrong. There is no book called "How to become a unity developer " :) | 20:12 |
| bobweaver | or even better "How to become a unity developer for dummies " though them books are junk anyways. maybe there is book for that but it is about gaming platform :) | 20:14 |
| bobweaver | of to learn thanks all | 20:14 |
| mhall119 | mhr3: bschaefer: ^^ any chance someone from the Unity team could spare an hour and to a hangout/classroom session on this? Seems it would help more than just the TV devs, but also anybody interested in contributing to Unity | 20:14 |
| mhall119 | an ubuntuonair.com session with screen sharing would be fantastic | 20:16 |
