I have a little problem when i start up ubuntu:
Every thing is normal untill after you see the loading bar with the ubuntu logo.
Then I get this error message:
Failed to start the X server (your graphical interface). It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem?
<Yes> <No>

I then click yes, and from what shows up, the problem is:
Parse error on line 659 of section screen in file /etc/X11/xorg.conf
"Modeline" is not a valid keyword in this section.

I have tried booting in safe mode, and i still cannot find a way to edit the xorg.conf file.
(No X server=No gedit=no: sudo cd /etc/X11, and gedit xorg.cong (to delete the Modeline cmd=I was messing around with it to get something to display correctly))

Any suggest a livecd that will be able to access my harddrive and be able to edit the xorg.conf file? (Damn small linux wont boot, for some reason)

Why do you need a live-cd? Can't you just use a command-line editor? Try nano if you don't have emacs and don't like vi. It's very intuitive. But any liveCD that will boot will fix that problem. If you're just looking for a liveCD recommendation, I'll go with SLAX, but others will tell you different things.

Note: I see you're on Ubuntu, so if you don't have nano, just type
sudo apt-get install nano
