Diamond Stealth 2500

[Jerry Callen]

   There are more than two, and do not appear at any fixed location on
   the screen.  They disappear if one moves a window over them.  When I
   ran "ico -faces", a whole bunch of them appeared at the right of the
   ico window, approximately 0.5" to 1" long (not all of the same length,
   and the spacing was not regular).

This sounds exactly like a problem I had with a Diamond Speedstar Pro
VLB card. In my case the lines were either all white or all black. Is
that the case for you, too?

The only way I could fix the problem was to specify "noaccel" (or
something like that) in the XF86 server configuration file. Since I
wasn't doing especially graphics-intense stuff, I never really
noticed much performance degradation.

What is it with Diamond? I eventually replaced my VLB motherboard with
a PCI board and got a Diamond S3-based (926?) card. It had this weird
8-pixel offset problem that was fixed by setting (cute...) the
"diamond" option in the S3 server config file. Works like a champ, but
it does seem that Diamond cards are subject to weirdness.
