Come now. It just isn't a proper internet discussion without a flamewar thrown
in. :)
I forget if you said you are using an LCD or a CRT. I believe you said you've
tried different monitors and different video cards. How about cables? Can you
switch between VGA and DVI cables?
Other things that come to mind.
- have you turned the brightness/contrast down
- if you don't need correct colors, can you reduce R, G and/or B until
whites are neutral or slightly on the red/yellow side?
- how about adjusting gamma?
- if a CRT, can you (or anyone with very good ears) hear a very high pitched
whine, nearly in the ultrasonic spectrum? A bad cap in a CRT will give
me a headache in mere minutes.
- if a CRT, does the display waver or shimmy at all?
That one GNU/Linux distro is OK and Debian causes trouble somewhat befuddles
me. Does Debian now stand for DEranges Brains In A Nanosecond? Should it be
nicknamed Torquemada? :)
