No console after Xserver crash
 
Hi all
Sometimes X crashes leaving me in totally «frozen» blank screen. I can't switch to another console, so i connect to my machine from another one and reboot. Is there any workaround for this? I mean, is there any way to get the console back without the need to reboot the system?

It's probably not just X that's crashing.

What is your video card and driver?

If this only happens during an X session, first look in (and/or post) the output from "/var/log/Xorg.0.log.old" after rebooting:

Code:
less /var/log/Xorg.0.log.old

It is X:

Code:

Fatal server error:
Caught signal 11.  Server aborting
Everything else works fine: i am able to connect to my machine via SSH and work with it like nothing happened. I checked /var/log/messages and other logs for errors - nothing special, just usual stuff.

Do the SysRq keys still work? (start with alt-sysrq-r to recover your keyboard)

I'll wait and see...it doesn't happens so often. It's not the crash that interesting me but how to get the console back.

It could also be HAL related (most new problems like that are actually HAL related).
I personally don't like how everything is starting to depend on it (in this case, SysRq will not work either since HAL handles all input).

You should be able to reverse this annoying behavior though:
