Some other tests make it look like it is not dependent on 3D acceleration or screen resolution. At 1024x768 I can just see a bit of it on the right hand side of the screen. At 800x600 I think the noise is off screen. > Why it would work in one OS, and not another, could be due to > different refresh rates being used, different modelines being > programmed, or the PLL's being programmed differently, or some > other timing sensitive item.

How can I change the refresh rates that the card is trying to run at? Actually, in both 16-bit and 24-bit modes I'm currently at 91kHz/85Hz. Presumably something in xconfig adjusts this? Maybe I could slow it down and provide someone with more info? Can I change between 16 and 24 bit without exiting out of X? Is ther a key pad way to do that? > You might want to discuss it on the XFree86 mailing lists also. > I will. Signed up a little while ago, but trying to do my homework first.
