Are you able to reproduce this issue with the latest updates to Jaunty? If so, please collect a full backtrace - see http://wiki.ubuntu.com/X/Backtracing for directions.

[Lars Ljung (larslj)]

Yes, this is very with the latest updates. I'm attaching the full backtrace as requested.

[Bob McElrath (bob+ubuntu)]

I confirm on this chipset:
    00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 0c)
    00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
    00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

This bug occurs when TexturedVideo is enabled (which is the default), and is independent of whether DRI is enabled. If you disable TexturedVideo via:
    Option "XvPreferOverlay" "false"
then you get bug #367546.

So, video playback is basically impossible on this chipset. :( Disabling xv (e.g. using gstreamer-properties) is too slow to run anything full screen.

[Bob McElrath (bob+ubuntu)]

This bug is fixed by the updated 2.7.0 driver at:
https://launchpad.net/~ubuntu-x-swat/+archive/x-updates/
However you MUST used TexturedVideo (again, the default anyway) so remove any XvPreferOverlay option from your xorg.conf. When this option is false, it causes a different bug and X crash. Works with DRI enabled too.

Can an update be pushed out?

[Bryce Harrington (bryce)]

Thanks for letting us know the issue is resolved in 2.7.0, which we now have in Karmic.

The SRU team does not permit "pushing out" entirely new versions of drivers; the x-updates PPA is the proper source for getting an updated video driver.

[Bob McElrath (bob+ubuntu)]

It was a poor decision to release Jaunty with this version of the driver. (Though I don't know if you had any choice from upstream) Jaunty also has massive speed problems in i.e. xournal which are all the driver's fault. There's some commentary on freedesktop about the crappy state of this driver. I'm quite disappointed in Intel.

I hope people can find this bug report and the fix for the next 6 months then...

[Tomas Pospisek (tpo-deb)]

I can confirm that the PPA drivers effectively fix the video-play->crash bug:

Updated Jaunty from version to version:
xserver-xorg-input-synaptics 0.99.3-2ubuntu4 -> 0.99.3-2ubuntu5
xserver-xorg-input-vmmouse 1:12.5.1-4ubuntu5 -> 1:12.6.4-0ubuntu1~xup~1
xserver-xorg-video-intel 2:2.6.3-0ubuntu9 -> 2:2.7.1-0ubuntu1~xup~1

Chipset:
Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

Thanks,

However, since upgrading to the PPA release, suspend stopped working. See bug 385497 for more info.

Installing the PPA release (2.9) doesn't solve this issue. Now I cannot play with mplayer fullscreen. Trying to do that will instantly kill the X server and restart the X session. I had to revert to 2.6.3
