Information by Debian's reportbug on package xserver-xorg-video-intel

* I'm tagging this as "critical" since it has caused me loss of work and data multiple times. *

Since the upgrade to Linux 2.6.38 am experiencing crashes on my laptops video.

First the screen was completely frozen and I had to reboot the system as was reported on http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=620480#10

After that I upgraded my xserver-xorg-video-intel package to the latest version available on Debian's unstable (sid) repositories.

Now the X Server is not freezing but still crashes and the display manager is restarted (KDM).

Most of the time this happens when I lock the screen, I suspect is because of OpenGL screen-savers.

Recently it happened when I put a video from http://www.jupiterbroadcasting.com on full screen, they use Flash for video viewing.

After the last crash I looked at the file /var/log/Xorg.0.log.old and found this at the end:

I am attaching the information produced by Debian's reportbug on package xserver-xorg-video-intel. It contains information about the video card, kernel, and system in general.

Thanks a lot for all the effort you put on making this drivers work!

Jaime, can you please install the libgl1-mesa-dri-dbg symbols and do a:

addr2line -e /usr/lib/dri/i965_dri.so 0x81522

to find out which line triggered the segfault.

Also note that you are using indirect rendering on the localhost, this is often undesired for the awful performance and loss of functionality.

According to glxinfo I'm using direct rendering. 
Am I reading it wrong? 
How else can I know direct rendering is not enabled? 
or How do you know? 
and most important: How can I fix it?

Here is the output of glxinfo:

I should have noticed KDE from the start. You've hit the KDE memory leak which leads to a segfault due to an unchecked allocation failure; fixed in master.

Beyond a doubt, kwin is using indirect rendering (as that is the path that crashed the xserver) and as it seems your system is not misconfigured (i.e. glxinfo is sane), kwin is *requesting* indirect rendering.

Created attachment 45815 [details]
KWin Desktop Effects configuration

According to KWin configuration Direct Rendering is being used.

Comment 5 Chris Wilson 2011-04-19 06:24:46 UTC

The stacktrace says otherwise. At least one app on your system is using AIGLX (i.e. indirect rendering), and your system has a resource leak causing an allocation failure. Then mesa-7.10 dies due to insufficient defence.

So all I have to do is wait for the next version of KWin to reach Debian
unstable?

I added an attachment (comment #4) showing current KWin's desktop effects
settings, it says direct rendering is enabled, so is all this a KWin bug?

Is all this currently fixed on newest KWin versions or should I report it to
KDE?

Thanks.

Comment 7 Jesse Barnes 2011-06-08 11:02:26 UTC

sounds like a server bug that may already be fixed (either by kwin using direct rendering and/or the server bug getting fixed.
