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)
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?
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 service. -Tony Hilliard (the one who reported the bug)
Oh, and: The computer suffering from the bug is a Dell system with a Nvidia Riva 128ZX. This card might differ slightly from others.
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. ------- Additional Comments From 09/14/99 22:58 ------- All is well in the state of Denmark - XFree86 3.3.5 works dandily. Thanks for your time (and the Red hat IPO offer!)
