Didier,

Thanks for replying.
I know about the libGL replacement, that is why I use the
'nvidia-switch' script supplied with the nvidia SlackBuild. It
basically switches back and forth between the nvidia and xorg libGL
versions (and some other libs).

I am hopeful about the nouveau driver, but I'll wait for it to become
officially "stable" before putting it on a production machine.
