Have you tried using "safe mode" from the LiveCD menu? That usually resolves display issues, though you will be using a low graphics mode during your Live session.

sudo dpkg-reconfigure xserver-xorg

Go through the on-screen directions and you'll set up pretty much everything again, including resolution.

With Karmic that won't work.
If you want a xorg.conf file you will have to create it:

Code:

Xorg -configure

That drops a xorg.conf.new file into the working directory, so just modify it as you see fit, rename it, and move it to /etc/X11 for it to work. Restart X and the new values will be used.

The safe mode trick should work. The only way I know to change resolutions on the fly for a graphical sessions is if X is running, so if you can't get X started or you switch to VT (by doing ctrl+alt+F1) you won't be able to do it. In this case the only thing you can do is making changes to xorg.conf.
