I screwed up the lightdm.conf file as superuser.

What I was trying to do: I tried to insert a command (xbacklight -set 50) that sets my monitor brightness at the lightdm config file. Now when I start my laptop, it gets stuck at the xubuntu loading screen, so I can't login.

Is there a way to go into the shell/command-line and fix the lightdm.conf file??

Press Ctrl+Alt+F1 to switch to a different virtual console. You will have a text mode login prompt.

Once you've done your repairs, you can switch back to the virtual console with the X window display by pressing Ctrl+Alt+F7.

If you want to have several terminals, you get 6 virtual consoles with a login prompt by default: press Ctrl+Alt+F2, etc.

Boot into recovery mode, when the recovery menu is up, use the "Root Shell" option to gain a shell, then remove the command in the lightdm.conf.

  • CTRL ALT F1 did the trick. Thanks anyway. – user1091856 Jan 14 '13 at 1:40

Got what I needed on Google.

Solution: CTRL + ALT + F1 at the xubuntu loading screen. Then gained access to the shell, used vim to edit the file and then removed the commands I had inserted on it that was preventing lightdm from starting..
