Why then does killing gnome-screensaver makes it work, 100% of the time?

Gnome-power-manager I guess we can rule out, I have made tests with
g-p-m killed, so not running (and checked that it was not restarted).

Both X driver bug and kernel bug sounds strange, because in twm/and lxsession
it is working without any problem.

So I conjectured composite extension and disabled the composite box in 
for metacity so that it does not use that one, but it didn't help,
still 100% reproducible.

Ok, 2.6.31 I can try.

Is there a way to disable KMS if it is compiled into the kernel?
