Display Question

[Hans Umhoefer <spudling@acm.cs.umn.edu>]

This is probably going to be a rather broad question but I'm looking for a 
little peace of mind. Of late i have been having trouble with my display. 
Sometimes it has a yellow tint to it. This happens off and on while I'm 
working on it. It began when I had gotten my monitor replaced because my 
old one died on me and thus it appeared to be a hardware problem so I 
convinced Gateway to send me another monitor (which didn't fix anything) and 
then a whole new motherboard (integrated video sucks, but if Gateway want's to 
send me a brand new mother board and processor because the vid card is 
goofy I'm not going to complain). None of these things fixed the problem, 
so I'm beginning to wonder if it's a software problem. I observed the 
first in Linux but it appeared in Win 95 as well. Now with the new board 
and all, Win 95 seems to be ok, however I still have trouble with it in 
Linux. I didn't think it was a software problem in Linux because I 
observed the tinting while I was working in console, X or running an 
SVGAlib application. I have an ATI Mach64 3d rage II and am running the 
latest redhat rpm's of the Mach64 X server, the SVGAlib support f the 
Mach64 seems to be lacking so I use a standard VGA driver when playing 
quake. Is there some software bug or setting that could be causing this 
behavior, or possibly damaging my hardware so that it begins to happen in 
Win 95 as well? I apologize for the broadness f this question but I'd 
hate to keep having Gateway send me new parts only to have it be 
something I was doing in Linux. Gateway is not very supportive of Linux 
and almost refused to help me with some other troubles I was having when 
they found out I was running it. I think they've forgotten about it or 
they wouldn't be sending me all this new stuff.

Thanks in advance for any help you can give. I realize this is a pretty 
broad topic.
