Description Jeff D. Hanson 2008-04-07 01:12:09 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.13) Gecko/20080325 Ubuntu/7.10 (gutsy) Firefox/2.0.0.13

Description of problem:
Fedora 9 beta w/updates.  Panasonic CF-51 with 855GME integrated video.
If I use the Fn+F3 display switch without an external monitor connected the system usually freezes. No log messages, no magic SysReq, no remote ssh, no LED toggling, no messages on serial console - just a black screen with a frozen mouse cursor. It doesn't matter if the monitor was connected when X was started. Even with it connected the switch doesn't seem to have any effect on display switching as the view is cloned regardless. There is only a small display flicker when the switch is actuated to indicated that anything happened (unless it decides to freeze).  I tried switching to the i810 driver but it can't find any devices.  The vesa driver works and switches correctly with the external monitor connected and doesn't misbehave if it's not.

Version-Release number of selected component (if applicable):
xorg-x11-drv-i810-2.2.1-19.fc9.i386

How reproducible:
Always


Steps to Reproduce:
1.Login to desktop with intel driver enabled.
2.Disconnect external monitor.
3.Attempt to switch to external monitor.

Actual Results:
Black screen with mouse cursor, system freeze.

Expected Results:
Either not switch or black out and return after subsequent key actuation.

Additional info:
A similar bug exists in Ubuntu Hardy 8.04 beta with a Toshiba M35X-S114 using the same chipset:  https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/213191
