Comment 50 for bug 71913

I am having the same problem with an integrated Intel card on a Dell GX620 Desktop machine:

The Xserver dissappears (crashes), turns my monitor to standby, and sends me back to the gdm login screen after a few seconds.

It has happened to me twice now, both times I have been un-minimizing Mozilla Firefox from the taskbar (by clicking it)

00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02)

Xorg.0.log.old provides:
