kubuntu not booting "no screen found"
 

just got back from hunting and my computer won't boot. I can boot to recovery mode and try #startx and it gives back [no screen found]. So I boot using live cd and everything works. Apparently my wife has been using the computer with no problems while I was away and then there was a power outage. My ups did not work [time for a new one] the box shut down with no battery backup. I don't know if this had anything to do with the problem or not. I did edit the /etc/X11/xorg.conf file to add some lines in order to use transparency. the lines are at the end of the file. I can comment them out if I knew how to edit from command line. I doubt that this has anything to do with it since I rebooted with no problem after making that change.

Please, any help would be greatly appreciated.

OK I know what the problem is. The /etc/X11/xorg.conf file has a bad ending. the last section "Extensions" ends with end instead of end section. Now I just need to know how to edit the file via command line. Unless there is a way of doing it from the live cd.
