Default How can I clear a hung video console caused by X server bug?

Hi

I've recently upgraded to slackware 10.1 and am using the new xorg
X server. Its a good server but it has a bug with my video card
(Matrox G200) in that when it exits it sometimes leaves the main
console screen in a mess , with no terminal sessions available.
I can still use the machine remotely but it is unusable with its
own monitor & keyboard etc. Killing the X server is no use since
its already dead , is there a command to flush the whole video
buffer and reset the console? I'm not using kernel framebuffers.

Thanks for any help

maning of 'a mess'?
Usually typing (blindly) ctrl-y reset ctrl-y send a reset to the
terminal and fix most problems.

A distored colour version of the last screen image before the X server proces
exited.

Its not a terminal issue , its a video card issue. The keyboard , mouse
and screen are totally locked up.

Try "Documentation/sysrq.txt" in the kernel docs, this options
could be useful:

'r' - Turns off keyboard raw mode and sets it to XLATE.

In addition, please let us know if this works for you? This is
just an idea what might help, since there are no problems with my
X, can't test if this would really help. It's just what I'd try
out and see if this fixes things. In addition to checking if you
graphics card would work better with a more recent X server and
update to this version.

Good luck
