Description William D. Hamblen 2005-04-07 11:43:28 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040626 Firefox/0.9.1

Description of problem:
Number 9 Revolution 4 video card.  Problem occurred with non-updated brand new FC3 install and also after I patched everything (including kernel and xorg-x11).  It only seems to happen after the second logout from X.   I already tried commenting out "Load dri" in xorg.xonf and that did not help.

The system is totally dead after the second logout.  Won't respond to pings, keyboard, or mouse.  Only the hardware reset button.

Version-Release number of selected component (if applicable):
kernel-2.6.10-1.770_FC3 xorg-x11-6.8.2-1.FC3.13

How reproducible:

Steps to Reproduce:
1. Login at GUI login screen
2. Logout
3. Login again
4. Logout

Actual Results:  System totally locked up with blank screen and no response to ping, kybd, mouse.

Expected Results:  New login screen.

Xorg.0.log from an affected machine

This is the log file after a hardware reset / reboot but before anyone has
logged in at the console.

The "i128" hardware does not have DRI support at all, so disabling DRI
should have no visible effect.  While we do not have this hardware
available for troubleshooting/debugging, you can file a bug report
to X.org directly, at http://bugs.freedesktop.org in the "xorg"

Once you have filed your bug report in X.Org bugzilla, please attach
your config and log file there also, and paste the URL of the X.Org
bug report here and we will track the issue in their bugzilla.

Troubleshooting tips:
Try disabling acceleration by adding the following to the device section
of the config file and restarting the X server:

    Option "noaccel"

If this prevents the problem from occuring, be sure to indicate that in
the X.Org bug report also.  After that, comment that out, and try the
various XaaNo options listed in the xorg.conf manpage one at a time and/or
in combinations to see if you can narrow down the particular primitive
causing the problems.

It's also possible the problem is due to the video state not being
properly saved and restored by the driver correctly.  A problem of this
nature will likely require someone who has physical access to the video
card, and can reproduce the problem to try to debug it.  There are some
X.Org developers who do still have i128 hardware available and might
be able to do this once you've filed your report there.

Hopefully this will help you to narrow the issue down.
