[Ubuntu-x-swat] [Bug 755841]
(In reply to comment #113) vsync seems to be fully working now on SNB/IVB with 2.21 and kernel 3.8, so the remaining issue is to get TearFree solid and performant for all use cases. Thanks for working on this. I have upgraded to Linux 3.8-rc7 and xf86-video-intel 2.21.2 on my ThinkPad X200 (Intel GM45) and on my workstation (Sandy Bridge GT2). On my X200, I can use the TearFree option without any side-effects. If I enable it on my workstation though, the result of terminal commands such as ls -hl or ps auxf often lags — the lines appear one after another, just like on a serial connection. Just wanted to let you know in case you were not aware of that yet. Let me know if you need any more details. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/755841 Title: [sandybridge] Graphics tearing when playing video To manage notifications about this bug go to: https://bugs.launchpad.net/compiz-core/+bug/755841/+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 755841]
(In reply to comment #96) If you have an unredirected fullscreen DRI2 application, then it will use pageflipping to update the scanout upon a SwapBuffers. So something as simple as 'mplayer -fs -vo gl' should be enough to achieve tear-free playback on most DE (you may have to tweak a few compositor settings if using one though). Is this also true when you use multiple monitors (xrandr output follows)? Because I use mplayer -fs -vo gl with xf86-video-intel 8066bc33d78e78ce7c13833b08a7daaea2f3ed22 (AccelMethod SNA, TearFree not set) and I do notice tearing.
