Hi,

I'm trying to get Knoppix to boot correctly to the mode I wish. My display supports 1280x1024 resolution at a refresh rate of 60 Hz. (LCD Display). When I let knoppix boot with the following parameters it defaults to 76 Hz, which I can't use:

knoppix26 fb1280x1024 vga=795

Is there a commandline parameter so that I can set the refresh rate to 60 Hz?

Thanks for any help,

Rindi

These are the two cheat codes available, I don't know if you can change that value but try it and post back.

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

Thanks for the answer, but it didn't help.

I already tried that without any improvement
