'preciate the response, Ray. I tried various resolutions. I also tried restoring an old copy of XF86Config and it too failed. Things are weird. I rebooted the PC; no good. xvidtune allows me to make some adjustments, but not to adjust the problem out. This morning, to test to make sure it wasn't the monitor or card, I rebooted and dual-booted into WinNT. Everything worked fine. So I rebooted back into Linux, and when X started everything was fine again. Weird stuff. If I try to bump up to 15 or 16 bpp, I get the weird stuff, but when I dropped back to 8 it straightened out again. The only thing I can figure is that the 15 or 16 bpp setting threw the card into some weird 8th and one-third dimension or something, and it didn't straighten out until WinNT reset the card somehow. At any rate, I'm back to a usable state at 8 bpp. Hopefully I can successfully bump it up to 15 or 16 later, but for today, I'll leave it alone.
