[arch-general] Strange X11 problem with fresh install

[Fons Adriaensen]

Hello all,

I'm experiencing an odd problem with a new system installed yesterday.

Video HW is NV44 [GeForce 6200 LE], driver nouveau, login xdm-archlinux,
windom manager is Windowmaker (but the same problem occurs with e.g. FVWM).

Every _second_ login the following happens:

* Input typed into xterm is displayed as spaces. All the rest (including
  completion and history) gets printed normally.
* The top pixel rows of some lines in xterm are not displayed.
* Apps displaying pixmaps show random garbage instead.

When this happens, /var/log/Xorg.0.log has a line

[    42.200] (EE) NOUVEAU(0): Error allocating scanout buffer: 0

while in the other 50% of cases there are no errors.

Any hints, options I could use to avoid this, ... ?

TIA,
