Quoting Harald Koenig from Xfree86 on the problems *I* have
with the S3 Virge GX: 
"yes, it's known -- but it's neither
_why_ this happens at all nor I'm close to sure that it's a
design/coding bug in the server.

quite some time ago I had similar problems with other ViRGE cards too
(I don't have any ViRGE/GX for testing) and I could track down the
problem to the fact that plain reading from video memory in text mode
(to save text mode fonts at startup) fails and returns
bogus data."

As you can see, it IS a well-known chipset -- buggy, but
well-known. This does NOT appear to be an X problem or a
Linux problem. I have a Virge DX that has a similar problem
in Windows 98. I'm probably going to replace it with
something else (My local computer store has some PCI Matrox
cards on sale! G)

There is a "known" bug in some implementations of the S3
chipset, according to xfree86.org. The problem *I* have
seen is that it messes up the console mode text after
quitting X. They attribute this to "plain reading from video memory in text mode
(to save text mode fonts at startup) fails and returns
bogus data." (Quote from Harald Koenig of Xfree86 team.)
Now, a commercial server MAY fix this problem. Matter of
fact, on S3's website they suggest Accelerated-X for Linux
users. Perhaps if you switched to Accelerated-X (there's a
10-minute free demo you can download) the problems you've
experienced would go away and the video performance would
likely improve.

 Well what video card are you using?  What version of Xwindows? Does
 your card have an acceleration enabled under Xwindows? Does it have
 acceleration under Windows 95?  If you answer these questions I think
 you can figure out your own problems.  
 
 From what I hear XFree86 4 will be a lot faster.  If you need the
 speed now check out the commercial X servers.  Nobody said that video
 was a strong point of Linux.  At least I haven't read anything like
 that!
