ive sort of got a problem like that myself right now...
ive got the old diamond stealth 32 card (vlb)....when i exit X for the
first time (or just switch back to one of the text consoles), it doesnt
restore the frequency for the monitor properly....
what i have to do is run the diamondclock program that is available in
sunsite, under X11/servers...it creates a program called freq which will
reset the frequency....then i run freq 28.15 1, which i put in a script
called rs to make it easy...
now, the first time i switch consoles in an X session, or exit X, i just
run rs, and it resets everything for me...
of course, i wish it wouldnt do it at all, but i just have to deal with
it until i get a real computer...
