When running Knoppix from CD I always get this message no matter what I do. This didn't happen before I changed to my new TFT Monitor with 18,1". I tried many options like: nodcc, xvrefresh=60|70, xmodule=vesa, fb1024x768, failsafe. Only failsafe made me see the console for a little longer, but as soon it turned to the xserver the screen gets blank and I just see "Mode not supported" (48kHz, 50Hz). What can I do to make Knoppix run again??? Thanks for any help!
