This one takes awhile because you have to try a bunch of different ranges.

First, get the specs of your monitor and find the horizontal and vertical refresh ranges. Then, start at the low end and use the refresh cheat codes until you find the right range.

Cheat Code:

knoppix xvrefresh=60 (or vsync=60) Use 60 Hz vertical refresh rate for X
knoppix xhrefresh=80 (or hsync=80) Use 80 kHz horizontal refresh rate for X

So, if your vert range is 43.5-60, I would start off with xvrefresh=44. (do the same with xhrefresh) and keep trying different combinations until you get the right range......then, you have to log in every time with that code.[/list]
