[gentoo-amd64] X locks up

[gentoo-amd64] X locks up

[Michael George]

I have been having trouble with my system.  For some reason, I've only
noticed it recently, but nothing has been updated on the system.

What happens is that sometimes (amazingly frequently) when I have open
office running on my right screen and I click "File", the displays will
freeze.  The system is still running, because I can get in from one of
my terminals.  I check and X is consuming 100% of one processor.

I can kill openoffice and ctwm (my window manager) reasily, but I have
to use -9 option to kill to get X to die.  Even after that, though, the
video and keyboard are still locked.  The only way I know of to get them
back is to restart the system.

IIRC, it only happens when OOo is on the right screen, but I can start
oowriter2, put it on the right screen, and click file and it won't
always lock things up.

System info:
openoffice-bin-2.1.0
xorg-x11-7.1
xorg-server-1.1.1-r4 (VIDEO_CARDS="mga", INPUT_DEVICES="keyboard mouse")
libXinerama-1.0.1
ctwm-3.7
Video card: Matrox G450
System starts up to a CLI login, not XDM

Anyone have any clue as to what is going on here?  Is there a way I can
release the hold on my keyboard and/or display so that I can just get to
the console so that I can reissue "startx"?

I had a similar problem for a while due to a bad video card. It was an nvidia, and I was able to fix it by switching to the nv (open source) driver, but that meant I had no 3d acceleration. I don't know if there's something similar you could try with a Matrox, you may just have to replace the card.

try removing the card and put it in its slot again

try a different PSU

check your board for 'strange' caps.

yes, that way is known as 'sysrq keys'. Please
