Description tones 1999-04-28 23:59:02 EDT
The SVGA driver for the Riva 128 chipset sends out-of-range
data to the video card, hanging the system.  I did not have
this problem with the XFree 3.3.2 shipped with RedHat 5.2

The problem can be "Resolved" by setting the refresh rates
of the monitor to very low levels (50-80, 30-70)
Comment 1 Preston Brown 1999-07-15 15:01:59 EDT
We need more information about your configuration, what modeline is
actually being selected that is "bad", etc.  Dave, can you verify this
as well please?
Comment 2 tones 1999-07-15 16:38:59 EDT
I am away from my computer (the one which suffered from the problem)
for the summer, and thus I can't check exactly where the "cutoff"
point is in the modelines.  I can say that 640 x 480 @ 8bpp & 60Hz
does work and 1024x768 @ 16bpp & 75Hz does not (though it was fine
under the previous version of XFree).  Sorry I can't be of more

Oh, and:

The computer suffering from the bug is a Dell system with a Nvidia
Riva 128ZX.  This card might differ slightly from others.
Comment 4 Preston Brown 1999-08-31 09:34:59 EDT
please re-open this bug when you are able to get back to the affected
system, and you have tested the situation again with the latest
available XFree86 updates.

All is well in the state of Denmark - XFree86 3.3.5 works dandily.
Thanks for your time (and the Red hat IPO offer!)
