This looks like a disagreement between the display and your XF86config as to the correct scan timing. There are a number of things you can do: 1. Check whether it happens in other resolutions. You don't say, but I suppose you were doing this at 1024x768. Does it still happen at 800x600 and 640x480? 2. Check whether it happens in other colour depths. If it doesn't, check the dot clocks. Your current ones are: > (**) Mach64: Mode "1024x768": mode clock = 75.000 > (**) Mach64: Mode "800x600": mode clock = 36.000 > (**) Mach64: Mode "640x480": mode clock = 24.000 3. I note that for 1024x768 you have the following mode line: ModeLine "1024x768" 75 1024 1048 1184 1328 768 771 777 806 -hsync -vsync I don't know if this is some decision by xf86setup that you need negative sync just for this speed, but I suspect it's bogus. You could try removing the -hsync -vsync and see if that improves things, though at the moment I can't see how.
