Bug Description


With the latest version of the intel-gfx-driver in Jaunty (xserver-xorg-video-intel_2.6.3-0ubuntu1_i386.deb), "totem" and "vlc" show only a green window when i want to play a movie on my notebook (855GM-chipset)

The bug can be easily solved, when the two following git-commits are backported to the driver 2.6.3 :

Fix Xv crash with overlay video :


Fix XV with non-GEM kernels by allocating a larger fake bufmgr. :

The "...but hopefully not anger tiny-aperture systems..." bit does not fill me with confidence. I'm tempted to skip incorporating these fixes out of fear of regression risk, but since we've had a few people complain about this problem I'm willing to give it a shot.

We may back these out if we find them the source of regressions though.

It may be a bug in xorg core, but since this update, I've got frequent X crashes.

They all happen when the monitor resumes from sleep after being blanked, or when it goes to sleep, or when mplayer/totem end playing a video.

Also, I've noted that, if you move a gnome-terminal window with black background and some transparency enabled over a totem window with compiz *disabled*, some of the video "passes" through the terminal (the areas where the wallpaper is black) and shows on top of it.

Should I open a new bug?

By the way, dmesg says:

[18285.236782] Xorg[18926]: segfault at 10 ip b78ea4c9 sp bf856400 error 4 in libdrm_intel.so.1.0.0[b78e9000+8000]

Do anyone know why apport isn't working, nor why I can't find a stacktrace in Xorg.<n>.log?

Sucks to be right. The regression here is 348428, which has been pinpointed to this bugfix. As bad as a green window playing movies sounds, the X lockups are worse, so I'm reverting patch 114.

115 sounds like it fixes a crash, so I'm going to try to keep that patch if it is innocent in the regression as I suspect.

So, additional analysis needs to be done to find a better, regression-free fix for this bug. If a solution comes to light, please assign this bug to me and I'll take a look.

I am not sure. I have removed some time ago both patches, at first the 115 and then the 114 and still got the same problem.

Intel 2.6.3-ubuntu5 doesn't fix the freezing/switching to console problem but xv is still working too. No green screen.

Stefan, what are your findings?

Stefan Glasenhardt (glasen) wrote :


The latest driver works for me. No more green screens.

Regarding the lockups a have a tip :

When i'm disabling all external monitor connections in the xorg.conf-file, the random lockups completely disappear (At least for me). The lockups occured sometimes when i'm watching a movie (Xv extension), used powertop or switched back from console.

I've attached my xorg.conf-file, so you can try it for yourself. Its not a perfect solution, but better than nothing.

In my case the easiest way to confirm the lockup issue is to run a video with xv - starting is enough - and then initiate suspend afterwards. X should crash after a short time and you should find yourself at the login screen.

Anyway the green issue was fixed a long time ago and hasn't reappeard with Intel 2.6.3-ubuntu5 so for my concern this bug could still be marked as fixed released.
