[Ubuntu-x-swat] [Bug 766647] Re: Natty - Windows MCE remote triggering events to lirc and as a keyboard making mythtv frontend unusable
The correct fix for this in Natty is this: echo lirc /sys/class/rc/rc0/protocols Just add that line to /etc/rc.local and it will be done at boot. This is not an Xorg bug but a side-effect of the kernel now understanding IR remote controls and generating keyboard events for them. You just disable the decoding and tell the kernel to send LIRC events and all is well. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-evdev in Ubuntu. https://bugs.launchpad.net/bugs/766647 Title: Natty - Windows MCE remote triggering events to lirc and as a keyboard making mythtv frontend unusable ___ 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 416604] Re: (UXA) xserver-xorg-video-intel 2D and 3D performance is much reduced from EXA
Results of further testing (with very bleeding edge kernel and xorg- edgers PPA) appear to show the problem satisfactorily resolved. $ uname -a Linux presto 2.6.31-020631rc7-generic #020631rc7 SMP Sat Aug 22 09:51:01 UTC 2009 i686 GNU/Linux $ dpkg -s xserver-xorg-video-intel|grep ersion Version: 2:2.8.0+git20090820.6955fc7a-0ubuntu0sarvatt~jaunty Device section of xorg.conf (the EXA and AccelMethod options are ignored and are hangovers from previous config, so in fact only 'Tiling' option is active): Section Device Identifier Configured Video Device Driver intel Option AccelMethod uxa Option EXAOptimizeMigration true Option MigrationHeuristicgreedy Option Tilingtrue EndSection Kernel modesetting is On. Boot time seems a little increased compared to user-modesetting, however, and there is a slight cursor glitch (display corruption near the mouse pointer) for a brief period after login. VT-switching is fast and smooth. In Xorg.0.log: (WW) intel(0): Option AccelMethod is not used (WW) intel(0): Option EXAOptimizeMigration is not used (WW) intel(0): Option MigrationHeuristic is not used Results: - glxgears about 340 fps, with drops to 240 and occasional peaks to 400. - ppracer 1280*768 about 24 fps, up from 12. This is the first time I have seen 3D performance improved with no corresponding change in the glxgears number, so it shows the advice to mistrust glxgears as well founded. - Full-screen flash (Youtube etc., 'HD' mode is smooth and OpenGL acceleration appears to be effective Note that the permissions of /dev/dri/card0 are still incorrect: crw-rw+ 1 root video 226, 0 2009-08-26 00:35 /dev/dri/card0 These permissions should be 666, shouldn't they? But manually changing the permissions and restarting X with kill -9 -1 does not change the graphics performance at all. Another thing I noticed is that it's apparently impossible to synchronise DRI with the screen vertical refresh, as was possible with the 2.6.30.5 kernel. Changing the values in .drirc or using driconf has no effect. I hope this information is of help to other users. I'm now much more confident that the Intel graphics regressions experienced in 9.04 will be resolved to an acceptable level in 9.10, and the process of performance optimisation has, according to blogs, only just got under way. ** Attachment added: Xorg.0.log http://launchpadlibrarian.net/30835030/Xorg.0.log -- (UXA) xserver-xorg-video-intel 2D and 3D performance is much reduced from EXA https://bugs.launchpad.net/bugs/416604 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. ___ 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 354940] Re: [i915] UXA is very slow (UXA bug)
With the following Intel controller on Jaunty/9.01: 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller [8086:2592] (rev 03) And updated kernel as recommended in http://ubuntuforums.org/showthread.php?t=1130582 Linux presto 2.6.30-02063003-generic #02063003 SMP Sat Jul 25 10:57:13 UTC 2009 i686 GNU/Linux Intel driver from PPA https://launchpad.net/~ubuntu-x-swat/+archive/x-updates/ Package: xserver-xorg-video-intel Architecture: i386 Version: 2:2.7.1-0ubuntu1~xup~1 xorg.conf Section Device Identifier Configured Video Device Driver intel Option AccelMethod exa Option EXAOptimizeMigration true Option MigrationHeuristicgreedy Option Tilingtrue I got the following results: PPracer, fullscreen 1280*800: UXA 11-15fps, EXA 25-30fps Fullscreen flash noticeably worse with UXA (tearing, dropped frames) The same ratio results (UXA giving about half frame rate and worse 2D video performance than EXA) was noted with the 2.4 Intel driver from Intrepid, Jaunty stock 2.6.3 driver, and the X-updates 2.7.1 driver. Performance with the downgraded 2.4 driver was noticeably worse (EXA). Upgrading from stock 2.6.28.15 kernel to 2.6.30 gave about a 20% improvement in framerate on ppracer. Hope this information helps someone. However, to say that a fix is released/bug resolved, when it's necessary to run an alpha of Karmic and a git version of the intel driver, is stretching a point a bit. It looks like most users will have to wait until the release of Karmic before they can watch full-screen video on intel chips (and even then, it's going to be marginal). -- [i915] UXA is very slow (UXA bug) https://bugs.launchpad.net/bugs/354940 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. ___ 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 354940] Re: [i915] UXA is very slow (UXA bug)
Retested with the following: xorg-edgers PPA intel driver Version: 2:2.8.0+git20090814.926c7e7d-0ubuntu0sarvatt~jaunty 2.6.30-02063005-generic 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller [8086:2592] (rev 03) Due to the 2.8.0 driver EXA is no longer available, so UXA is used whatever is in the config file: (WW) intel(0): Option AccelMethod is not used #new comment line in Xorg.0/log Unfortunately, I can't confirm William Grant's test results on Karmic, above. With this combination (tested both with and without kernel modesetting) the framerate in ppracer is cut to 11-14fps, and fullscreen video is choppy. This is roughly what was achieved with 2.6.3 or 2.7.1 drivers with UXA, and is about half the EXA framerate. It seems this degradation does not apply to all Intel chipsets, since https://wiki.ubuntu.com/X/UxaTesting has users reporting improved performance.
