    Screen Goes Blank After Loading Knoppix

    I'm brand new to linux, so please go easy on me.

    I've burnt knoppix to cd and manage to boot from it on one of my PCs.
    It boots up and when it says "press enter to load LiveCD" I press enter. Then after a second or so it says something like:
    "You passed an undefined mode number"
    "Press <enter> to see video modes or press space to continue"
    I press space and then it proceeds to load Knoppix.
    After a while it says "Loading X Windows" and then my screen just goes black and nothing happens.

    Please can you explain how to fix this!

    Thanks a lot,
    raZer

    The
    "You passed an undefined mode number"
    can be ignored. You can enter a zero "0" or just press enter.

    It sounds like knoppix is doing the best it can at autodetecting the video hardware (perhaps getting it wrong) & then setting a resolution & refresh rate that is beyond the capabilities of the hardware. Try booting knoppix with some Cheat Codes, such as:
    knoppix screen=800x600 xvrefresh=60
    knoppix screen=640x480 xvrefresh=60

    I hope this helps.

    Thanks James.

    How do I enter cheat codes?
    Must I type it in when it says "press enter to boot knoppix"?

    It still says "you have passed an undefined mode number" after I enter the cheatcode and then it proceeds to load up with a small font and then gets stuck at the same place!

    Is there some way I can use it without having this X Windows thing?

    You didn't bother to read the Cheat Code article in the wiki (reached by following the documentation link near the top of this page), did you? I say this because you likely would not have asked this and your later question if you had.

    Verifying of md5 checksum and burning a CD at slow speed are important.
