[Ubuntu-x-swat] [Bug 600178] Re: Screen tearing when dragging window, in videos and other large screen redraws (on nVidia GPU)
Yes, it is. At least it was when I last checked – a week ago or so. There is one difference though: when you enable full screen redraws in ccsm, the tearing stops – no additional steps are necessary as far as my experience goes. It does not even seem to be required to force enable vsync for OpenGl in nvidia settings any more. All in all, not very impressive, but still slightly better than in oneiric, I would say. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/600178 Title: Screen tearing when dragging window, in videos and other large screen redraws (on nVidia GPU) To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/600178/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Hmm, that does not seem to work for me.

[Ubuntu-x-swat] [Bug 600178] Re: Screen tearing when dragging window, in videos and other large screen redraws (on nVidia GPU)
I can as well confirm that I do not get tearing with compiz when I enable Force full screen redraws. I've used the video you posted to test – thank you very much for the link by the way. I first started to experience tearing in 10.10. Although back then once I enabled vsync to be forced for OpenGL the problem disappeared for as long as I used compiz. In the new version of compiz (0.9.x) though, there are obviously some bugs concerning redraws – some regions of the screen often seem not to redraw properly as if they were wrongly marked as unchanged. This issue causes a multitude of problems one of which probably is that the tearing is now visible in OpenGL mode as well. At least the fact that the tearing disappears once we force full screen redraws seems to indicate this... So I basically think we might be facing two issues here – one in the nvidia driver/x server that causes the tearing in the first place and then another one that now makes it happen in OpenGL mode with vsync enabled as well. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/600178 Title: Screen tearing when dragging window, in videos and other large screen redraws (on nVidia GPU) To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/600178/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 600178] Re: Screen tearing when dragging window, in videos and other large screen redraws (on nVidia GPU)
For some reason the attached workaround seems to work for some people (see http://ubuntuforums.org/showthread.php?t=1742643&page=4) including me. I do not fancy having the whole screen redrawn on every repaint, but it seems rather interesting that it works. Also – the solution proposed in comment 41 (https://bugs.launchpad.net /nvidia-drivers-ubuntu/+bug/600178/comments/41) seems to indicate that vsync for OpenGL works even though the one for x-server does not. Unfortunately in dual-screen setup it only affects the main screen (DFP-0), while the secondary screen continues to show tearing. --- The mentioned workaround --- Open CompizConfig-settings manager (if you don't find it, just install it from Ubuntu Software Center).

Are you sure that it does not happen with mutter? As far as I can see it happens in any type of session – unity, classic, classic with no effects, unity 2D, even if I explicitly call mutter --replace. It is true that it is nvidia-specific though. It might be interesting to find out whether this issue is present in other distros – Fedora 15 has just been released, perhaps it uses xserver 1.10 and the current nvidia driver. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/600178 Title: Screen tearing when dragging window, in videos and other large screen redraws (on nVidia GPU) ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 600178] Re: Screen tearing when dragging window, in videos and other large screen redraws (on nVidia GPU)
This is release is a joke... :D I have even tried to downgrade the xserver and the nvidia driver to those present in maverick but that didn't seem to work at all (which is surprising to say the least as this worked for me on maverick). Disabling compositing does not work either. I have tried the xorg-edgers versions of the xserver and nvidia driver, I've tried the 2.6.39 kernel in case that made any difference, which it didn't. If anybody has further ideas, please share. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/600178 Title: Screen tearing when dragging window, in videos and other large screen redraws (on nVidia GPU) ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 654654] [NEW] Maverick RC won't boot with modesetting
Public bug reported: Binary package hint: xserver-xorg-video-nouveau Maverick RC (and daily builds till this point) won't boot with modesetting enabled. It starts booting, plymouth displays correctly on external monitor, which has smaller resolution and incorrectly on the internal monitor, where it displays in the same resolution as on the external monitor and the rest of the image is corrupted (shows black, white and coloured dots). In the next stage, where the login screen should appear the display becomes entirely corrupted (again showing black, white and coloured dots) and the system freezes completely.
