Bug#483206: [xserver-xorg-video-intel] Xorg: screen gets blank randomly, and there is no way to recover
Package: xserver-xorg-video-intel
Version: 2:2.3.1-1
Severity: normal
--- Please enter the report below this line. ---
I was writing an email in icedove, suddenly the screen went black
(backlight still on).
I switched to VTYs, and I could run commands, but switching back to X
gave me a blank screen again. I tried typing, moving the mouse, with no
results.
I have started x11vnc from a terminal, and connected remotely, however
all I got was a black screen.
I also tried suspend-to-RAM, but it didn't bring me back the X console
either (and neither did vbetool dpms off/on).
I had to reboot (restarting just the X server didn't work either)
I don't know how to debug this if it happens again. Any suggestions?
Also, I never had such problems before upgrading to version 2.3.1 of the
intel video driver.
E.g. now sometimes when I login X is killed, and restarted, the 2nd
login works fine. Unfortunately it is not always reproducible.
I am running a 2.6.26-rc1 kernel, should that matter.
