Summary0002223: Random blank screens on X restarts.

 After logging out of a user session gdm restarts to a blank screen (LCD
 backlit but black), more specifically, the behavior appears to be a
 random selection of either restarting to a blank screen or restarting
 perfectly correctly. Issuing /usr/sbin/gdm-restart repeatedly from
 another VT will always, eventually, cause a successful restart.
 Failure rate appears to be about 50-70%.


 Dell GX280, CentOS 5, fully patched, gdm

Xorg details (from /var/log/Xorg.log):

Investigation so far:

    - Behavior is the same if using kdm

    - Xorg.log entries are identical in the cases of both successful
      and unsuccessful restarts.

    - With gdm debugging info turned on, relevant syslog entries are
      the same in cases of both successful and unsuccessful

    - Moved the hard drive into an identical machine and the same
      behavior is exhibited. (Rules out flaky hardware?)

    - I am completely stumped.

I'm happy to provide additional details as requested. Thanks,

I, too, have a Dell GX280 exhibiting the same symptoms. I had Fedora Core 4 on this machine and after reinstalling with CentOS5 it started giving me blank screens at random.

My symptoms are exactly ike Albert's. Just wanted to add another data point.

Seeing the same issue here across a lab of GX280s. Haven't found a solution yet but I did notice that the gdm screen will immediately reappear if you push the mouse a long ways towards the upper left corner of the screen.

Seriously hackish work around here:


Uses a tool called xdotool to simulate the mouse being pushed to the upper left corner of the screen just after GDM loads.
