Description Bryan Christ 2009-04-14 11:37:46 EDT
Description of problem:

Changing the screen resolution with gnome-display-properties cause the screen to go white.  Killing the server with ctrl-alt-backspace has no effect.  Switching to a standard VT also does not remedy the problem.  The only way to restore the screen is to (blindly) switch to a VT and hit ctrl-alt-delete.  After reboot the screen was restored.  I tried changing my resolution from a higher one to both 1024x768 60Hz and 1280x1024 60Hz.  Both of these resolution changes manifest the problem.

Version-Release number of selected component (if applicable):


This did not happen until the latest update from rawhide (4/14).  I did an update on 4/13 from rawhide and all was fine.  Something broke in between.

How reproducible:  100%

Steps to Reproduce:
1.  Install F11 beta1 (32-bit) from DVD
2.  Fetch latest updates from rawhide
3.  Try to change resolution with gnome-display-properties
Actual results:

White screen which will not go away without reboot.

Expected results:

Normal resolution change.

Additional info:

System in test is a Compaq dc7100 with integrated intel 915 graphics.
Monitor is a Compaq P700

Booting with the previous kernel ( did not fix the problem.
Comment 2 Bryan Christ 2009-04-14 11:46:26 EDT
After booting with the kernel, I still had the problem, but on the subsequent reboot (back to the kernel) the resolution changes were kept and the screen did not go white.  I am also now able to change the resolution from 1024x768 to 1280x1024 without seeing the problem.
Comment 3 Bryan Christ 2009-04-14 12:03:10 EDT
After a subsequent reboot, the problem has returned.
Comment 4 Adam Williamson 2009-04-16 17:31:10 EDT
Sounds like something strange going on when the card is initialized, but - we're going to need your X log (/var/log/Xorg.0.log) and /etc/X11/xorg.conf if it exists.

It would be particularly interesting to see /var/log/Xorg.0.log after the problem has manifested. Can you trigger the bug, then reboot *directly to runlevel 3* - add '3' as a kernel parameter - and take a copy of /var/log/Xorg.0.log before starting X? That should be the Xorg.0.log from before the reboot, when the problem triggered, and that's what we'd like to see. thanks!

no xorg.conf
Comment 6 Bryan Christ 2009-04-17 12:02:08 EDT
Attaching the requested log file captured from a reboot to directly to init 3.

Retested with kernel- and xorg-x11-drv-intel-2.7.0-1 and problem seems resolved.

I would recommend closing this bug as fixed and I can reopen if the problem returns.

sounds good to me!
