    ignore video card?

    Hello,
    I have a Dell laptop with a dead graphics card. When I boot from DVD, Knoppix seems to be fine until it tries to start X. Then it hangs. I've tried some cheat codes including vga=normal, but no success. I suspect that the dead graphics card is the problem. (Since it is a laptop, it is not really reasonable to remove it.) Is there a way to tell Knoppix to ignore the video card and just use the motherboard graphics?

    Thanks.

    uhm, what? dead? if you can see graphics when starting knoppix you are likely using that very graphics card, if not some special thing for external TV or something.
    uhm try "knoppix 2" for start, that will put you in console mode (text only).

    oh, another thing, it MAY be that the "memory" is dead on that card, that would make it hard to work with. check BIOS setting if there is some setting that allows it to use the first 16M only or something (seen one old laptop that had that setting)

    Thanks for replying.

    Perhaps dead is going a bit far. However, it doesn't work right any more. It won't get through a bootup unless it is disabled. Apparently Dell/Nvidia had a problem with graphics cards overheating and failing. Anyway, if I tell Windows not to use the graphics board, then it works relatively ok for most purposes. As near as I can tell, laptop motherboards are like normal ones in that they come with onboard graphics. I want Knoppix to use that instead of the graphics card.

    I would just remove the graphics card, but it has a heat sink that apparently runs through the laptop such that you almost have to disassemble the whole laptop to remove it.

    What version of Knoppix are you using? And which laptop and/or video adapter? There is some issue with the latest version (6.4.3) and Nvidia, it seems. The issue of switching to another internal/onboard adapter would be in the BIOS settings, most likely.

    Hope that helps!

    Knoppix v6.4.3. I tried one of the v5 Knoppixes too with the same result.

    Inspiron 7000 with Nvidia GeForce Go 7900 GTX.

    Since you suggested BIOS, I looked and found a setting that might work. I tried it, but it didn't work either. I haven't tried the cheat code tricks yet though.

    Thanks.

    Knoppix 6.4.4 DVD and NVidia woes

    <span style="background-color: #99FF99;">I've got the fated combination and was wondering if you knew of anything I could do about it. The graphics and xserver seem to start ok but the display is garbled with offset columns and crap. I tried 2 monitors with the same results. The actual machine is an Acer Aspire (AST180-UA380B). Lspci gives me:

    Solve garbled or scrambled video on ATI / Radeon / AMD graphic cards

    Had the same problem on a computer with an Asrock mobo with AMD 880G chipset. Knoppix LiveCD started allright, but ended with a garbled or scrambled screen.
    If the first bit starts up OK with text mode screens, then wait until you see 'Boot: '
    There it waits a couple of seconds, so you can enter something (namely, cheat codes...).
    After 'Boot: ' you type 'knoppix nomodeset' and press <enter>
    Solved the problem for me!

    I've put in a lot of keywords in this message so it may be found better by search machines.
    Also, I described the procedure, it took some time before I found that out!
