Thanks Ryan for your answer, and advice. >I doubt it, MMIO only refers to a manner of accessing the hardware >registers. It is usually faster than PIO so it is preferred when >possible. Can MMIO be enabled ? >This sounds like a modeline problem. Have you played with xvidtune to >see if it can help? I tried xvidtune, and I can get better display, but vibrations are still here. >Or perhaps try a lower resolution.

I tried with lower resolution and it was the same problem, under linux. Using windows, I did not have these vibrations. I can use 800x600 and 65536 colors (2exp 16, 16 for depth) settings. With linux, I cannot get 800x600 + the depth 16. When I set thousands of colors, the resolution downgrade automatically to 640x480! Concerning the settings of xvidtune, I realised that depending on what I tried, I got a screen more or less white. And under windows, the screen is much more dark.
