Thread: Problem with my monitor when booting knoppix?

    Problem with my monitor when booting knoppix?

    I Just downloaded knoppix and burned with nero. It boots into the cd and finishes loading drivers for my Hardware and when it goes to the next screen the monitor acts like the refresh rate is too high and it shuts off....what would cause this and how can I fix it. Thanks!

    Just as a note I tried to go in and use some of those cheat sheet codes and none of them worked:

    knoppix xvrefresh=60 doesn't work ( And my monitor supports 85htz at 1152x864 )

    Help?

    Try knoppix vga=normal or noddc to stop auto-detection of the monitor. You may want to try one of the fb images like fb1024x768 and of course there is always failsafe which will boot with minimal hardware detection. Maybe even knoppix vga=normal screen=1152x864 xvrefresh=85 also you never mentioned your video card you may want to use the xmodule=?? cheat code for the card replace ?? with the correct module name eg. nv (Nvidia), ati (ATI)

    Thanks a lot!!! I will go try it right now.

    BTW I have a Gforce FX @ 290/405..only gets 5586 on 3dmark2001 Wish I would have held out for the 5600 ultra which is now at 160$

    Which video adapter (graphics card) do you have? Which monitor? have you tried the [Ctrl]+[Alt]+[keypad +] on-the-fly resolution-switch function after boot?
    Also:

    I missed this message earlier, or I would have responded then...

    I had this problem also and I tried the [ctrl] [alt] [+] and it worked!

    [ctrl] [alt] [+] worked for me too, but I got a horrible bad resolution. This way I could find out, that my gfx card wasn't detected correctly. Starting with the cheat code xmodule=radeon it looks much better...
