Thanks, I did as you suggest, it really works and degrades my refresh rate, but I got another problem: my monitor begin to flicker. I check the current mode and find the dotclock also degrade from 78.8 to 60, I am not sure if it is the reason of flickering. I also know from others reply that it is good to live with 75HZ refresh rate, now I am just curious and want to make further investigation because in win2k, 1024*768@60HZ can work without this problem, I just do not believe linux can not do it. Is there some ways to increase dotrate? Or avoid flickering at 60HZ refresh rate?
