Bug Description

Binary package hint: xorg

Hi there,

latest drivers installed by either distro repo or by the installer
with Ubuntu maverick fail often and regularly.

Always reproducable using x264 video and vdpau output via mplayer and
doing resizes ff/rwd of video.

Also occurs doing simple things (open firefox/ view menu of
application launcher).

DPMS "off" makes slightly more stable although still crashes with mplayer test.

Have tested against 2.6.35-17 and 2.6.35-19 maverick amd64 kernels.

Have also tested with xorg-edgers ppa xorg versions but with same results as described here.

System hangs, often still able to get in via network, however doing
intensive things (cat large syslog ) will hang the process.

Xorg and any offending triggering application cannot be killed
manually. gdm restart also does not work.

shutdown now and reboot will not trigger reboot. Power must be cycled.

Attached are various dump I was able to obtain during a freeze.

nvidia-bug report hangs during collection so may be incomplete.

Also the ABI for the 256.44 drivers is out of date and needs updating,
but this is a seperate issue to the general instability.

Have attempted using xorg-edgers ppa with same result. Also attempted
to use the 256.35 drivers but it complains of missing linux-vdso.so.1
library and X does not load.

Dumps of various relevant system info during a freeze (oops output etc in kern.log running processes etc)

Please note that the installer log info in the nvidia bug report shows the old installer log where attempted manual install of .35 beta driver. This was removed and the dump relates to the repo supplied nvidia-current (256.44) drivers, it is valid just a little misleading at the top.

I manually verified all the manual nvidia installer components had been removed.

Will attempt tonight with fix proposed here :

I am unsure if Arturs, comment relates just to the x screen issue or the general instabilities reported here.

Am hopeful based on this changelog:

Changelog from upstream 256.52

  * New upstream release. Changes since 265.44: [sic: 256.44]
   - Fixed a bug that prevented XvMC from initializing in most cases.
   - Added support for xorg-server video driver ABI version 8, which will
     be included in the xorg-server-1.9 series of releases.
   - Fixed a bug that caused extremely slow rendering of OpenGL
     applications on X screens other than screen 0 when using a compositing
   - Fixed a regression introduced after 256.35 that caused stability
     problems on GPUs such as GeForce GT 240.
   - Fixed a slow kernel virtual address space leak observed when starting
     and stopping OpenGL, CUDA, or VDPAU applications.
   - Fixed a bug that left the system susceptible to hangs when running
     two or more VDPAU applications simultaneously.

I can reproduce it by running emacs23 with its gtk gui.

but i might be encountering another bug, i'm using both xinerama and twinview, i can't trigger it when xinerama is disabled

Running stable under test conditions reported above with 256.52. vdpau now does not lock up computer, have not had locks ups during normal compiz enabled ubuntu-desktop settings. Switching VT's also is ok.

I have not however tested with DPMS turned back on as of yet. And have not tested with Twinview.

I have in the past turned off xinerama as it has caused issues for me.

Will do some more testing with the .52 release over the next couple of days.

ignoreABI is no longer required with .52

Would recommend this goes into Maverick base and possibly Lucid.

downgraded xserver-xorg and nvidia*, not crashing anymore with the ones from lucid.
