Dear David,

I Experienced (another) lock few days ago..  Although
it seems that after turning the hw accelereration off in OpenOffice,
things are getting slightly better (fewer locks).

Since I am degugging this "statistically", I don't want to type
those grub parameters each time I boot my computer.  Is there
any way (config file, etc.?) to force those parameter automatically
each time my laptop boots.  .. I was looking in yast => bootloader
(grub), but at first glance, I could not find any suitable line
for typing those parameters in.

Cheers,

Sampsa
