    Monitor goes "Out of Range"

    I recently installed Ubuntu 10.4 onto an older computer. Upon trying to boot off the live CD, my monitor would go "out of range" (screen would turn black and display a hardware error message "out of range"). I was able to select the nomodeset option (F6 -> select nomodeset at boot options) to fix the issue temporarily, and then successfully install Ubuntu.

    However, I cannot get around the "monitor out of range" problem when booting Ubuntu from my HD. I have tried both adding "nomodeset" to the kernel options after "quite splash" (boot -> hold shift -> edit kernel -> ctrl + x to boot) as well as replacing "quite splash" with "nomodeset". I read to do this from a few other forum posts, and I believe I am entering these terms in the correct fashion, though i could be wrong.

    I also went ahead and booted into the linux 'recovery mode', and successful added:
    Code:
    GRUB_CMDLINE_LINUX="nomodeset"
    to /etc/default/grub after changing the file's write permissions.


    I don't understand how "nomodeset" fixed the problem when booting off the livecd, but doesn't fix the issue when trying to boot of the freshly installed OS. This leads me to believe that I am not editing the kernel options properly, but I cant figure out what exactly I'm not entering or entering incorrectly.

    The video card installed on the machine (no onboard video) is a nVidia FX 5500 and the monitor is a old LCD that runs (IIRC) 1024x768 native resolution.

    This is the guide i was following to try and remedy my problem.

    I also ask this question here:

    Re: Monitor goes "Out of Range"

    This issue is that grub is using a frequency higher than your monitor can display.

    Please do this to force it to match your LCD:

    Code:
    gksudo gedit /etc/default/grub
    and change this line:

    #GRUB_GFXMODE=640x480

    to this:

    GRUB_GFXMODE=1024x768

    Then save and exit the document.


    Then do:

    Code:
    sudo update-grub

    "gksudo gedit" and "sudo gedit" produce the error "Warning: Cannot open Display."

    I tried manually adding the line GRUB GFXMODE=1024x768 with a normal "sudo nano", followed by sudo update-grub.

    This all seems to have processed, but I am still receiving a monitor out of range error.
