[i946GZ] X gets stuck in D-wait state at logout

[Martin Schwenke]

Binary package hint: xorg

On Ubuntu 8.10, attempting to logout from GNOME often leaves the X server stuck in a D-wait state:

  root 5096 1.7 0.9 25484 19660 tty7 Ds+ 14:29 8:25 /usr/X11R6/bin/X :0 -br -audit 0 -auth /var/lib/gdm/:0.Xauth -nolisten tcp vt7

The box has one of these:

  00:02.0 VGA compatible controller: Intel Corporation 82946GZ/GL Integrated Graphics Controller (rev 02)

I'm attaching Xorg.0.log, which hasn't had anything written to it
since gdm start time. However, it does tell us that the version of
xorg-server is 2:1.5.2-2ubuntu3.1. I also have this version of the
intel driver installed:

ii xserver-xorg-video-intel 2:2.4.1-1ubuntu10.4 X.Org X server -- Intel i8xx, i9xx display driver

This is the latest version from intrepid-updates.

My xorg.conf has no customisations - just a bunch of boring default
sections. This setup worked fine under Ubuntu 8.04, although I had to
add a custom modeline and Virtual config. However, none of that is in
my current xorg.conf.

[This is an automatic notification.]

A new major version of the -intel driver is now available in Karmic.

This version includes a major reworking of the acceleration
architecture, which resolves a huge number of issues. We do not know
whether it resolves the issue you reported.

Would you mind testing Karmic Alpha-2 and seeing if it is still a
problem? CD ISO images are available here:

  http://cdimages.ubuntu.com/releases/karmic/

If the issue can still be reproduced on karmic, please report here with
your findings, and attach a fresh Xorg.0.log from your test, and we will
be able to forward the bug upstream.

Otherwise, if the bug no longer exists in Karmic, let us know that as
well.

In the off chance you encounter different bugs while attempting to test
Karmic, please report those as new bug reports.

I don't think I've seen this particular bug since upgrading to Jaunty.

That said, I've also switched to the -generic kernel from the -rt one for most uses... and have seem a big improvement in stability.

Thanks for letting us know the issue is resolved.
