    When you boot to your Ubuntu LiveCD you can add optional boot parameters that make small modifications for precisely situations like this.

    Boot to your CD and you will see an icon of a small "man figure" at the bottom - when you see him press any key on your keyboard. You will be given some options - your mouse should work.

    See if any of the options allow you to choose a resolution. If not you will need to append your own option by typing it in:

    Type this: vga=791

    This will give you a 16-Bit 1024x768 resolution that should work on almost all modern graphics cards.

    display - Monitor out of Frequency

    From what I can tell this hasn't been asked so I will

    Me and a mate have just upgraded my hardware ( RAM and graphics card). When I plugged a monitor into the computer after the upgrades, this was displayed on the monitor:

    hf:30khz- 60khz
vf: 50hz-75hz
current frequency
hf 64 vf 60

    Now as you can see it's obvious that the current frequency is greater than the accepted frequency. The problem is that I do not know how to change these settings. Any ideas?

    Answer for XP: In safe mode, you won't be able to change the resolution (or set refresh rates). Safe mode boots XP using a generic VGA driver, not the graphics driver you have loaded; this allows you to recover from video-drivers-gone-wrong type problems. Instead of booting into safe mode, you'll need to boot into VGA mode. This isn't very well documented as far as I can tell; as best as I can recall, you'll need to do the following:

    Hit F8 twice right after the computer boots. You'll see more options than you'll typically find in the normal F8 boot menu.

    One of the options is VGA mode; select that option. XP will boot like normal, except it'll force the video card to boot at 640x480 with 4 colors @ 60hz. From there you can change the display settings however you want. You won't even need to reboot to get out of it.
