logout freezes system
when I log myself out from X the screen shows starnge vertikal lines.
The system doesn't react anymore (no keyboard, no mouse, no ping from
another host; just hard-reset)
This happens only sometimes / is not reproducable.
It's not WM specific. I'm running potato with a custom 2.2.18 kernel and
Can you give me any hints, where to look for system messages that might
help and/or which debugging options I could use (for X / xdm?)?
