Hmmm. I've never tried it on a PowerBook. I guess I will have
to see if I can borrow one from around here to play with. Unfortunately,
that means it's unlikely to be fixed in 4.3 (I recall having a difficult
time with Linux PPC installation).
Can you VT switch back to the X-server OK, and startx again after
quitting? If so, it's probably just a matter of not enough stuff
being saved and restored in the UnLoad/LoadStateExt functions in
riva_hw.c. Probably some of the CRTC registers, possibly something
specific to the PowerBook. I supposed it could also be an offb
issue.
If you wanted to collect some data you could try reading
chip->PMC[0x00000004/4] at the top of nv10GetConfig() just to
see what state that was in before the X-server touched it.
Have you tried it in different depths?
Mark.
