I removed lightdm and all its config files in the different directories (don't ask).

How do I restore it?

elementary boots into text mode right now.


It depends on what all you deleted. The reinstall command from the command line is

sudo apt-get install --reinstall packagename

lightdm package is "lightdm" loki also uses "pantheon-greeter". Try reinstalling those two.

  • I tried doing that, and dpkg-reconfigure, but nothing good happens. – nkkollaw Nov 8 '16 at 8:13
  • Did you try reinstalling "light-locker" too? – Michael Roberts Nov 8 '16 at 15:51
  • I did't try light-locker, I'm getting lots of errors right now. – nkkollaw Nov 8 '16 at 22:01
  • What kind of errors? – Asu Nov 11 '16 at 19:51

I did exactly the same thing and panicked after elementray os booted into a command line, after trying a lot of solutions this worked out for me: login as administrator by typing your username and then your password and then type the following commands:

sudo apt purge elementary-desktop
sudo apt install elementary-desktop
sudo reboot
