Can't escape from COMMAND LINE, get back 2 DESKTOP
I just loaded up the Ubuntu 10.04 onto a newly scratch built computer. It went to the desktop after loading up and asking for my password. I then navigated to SYS>ADMIN>DRIVERS and preceded with download of recommended drivers for Nvadia G430 on-board display adapter. Restarted the computer to activate the new drivers and it's stuck in COMMAND LINE MODE.
I tried Ctrl/Alt/F7 to escape, along with a bunch of other things but nothing will kick this puppy into the DESKTOP. Help me get this computer running, thank you all.
