First of all, I was wrong about the cursor: it was not blinking.

This was actually [Ctrl+Alt+F1] and so forth, as you may have guessed.

The most important thing to notice within this update is that I was probably wrong about the screenhack that is running when the crash happens. It seems that xscreensaver-demo is not able to remember the last running screenhack after the crash (or, maybe, after the consequent reboot, I don't know) and it just shows that last enabled screenhack it can find inside ~/.xscreensaver This happened to be unicode-screensaver, until I disabled it (in the hope to work around the bug). Now I again experienced the crash (on both the boxes! during the same pause!), with unicode-screensaver disabled: hence it's not unicode-screensaver that triggers the bug! After the reboot, inside a newly started X session, running "xscreensaver-demo" shows rubikblocks, which is now the last enabled screenhack found inside ~/.xscreensaver So, in summary, I don't know which screenhack triggers the bug, but disabling unicode-screensaver does *not* help. The problem seems to occur every time I leave the boxes alone with the display locked, or even with just xscreensaver running (without locking the display). I raised the severity of this bug report, since experiencing a crash every time the X session is left alone makes xserver-xorg-video-intel unusable. Please do not downgrade the severity, so that other users are warned to not upgrade the package on their (Intel integrated graphics powered) systems, until this issue is fixed. -- http://www.inventati.org/frx/frx-gpg-key-transition-2010.txt New GnuPG key, see the transition document! .....................................................
