I have incidentally removed lightdm,
sudo apt-get purge lightdm.
Now I am not seeing login screen when starting the computer.
(only black background.. nothing else)
How to restore/install it back? I am using ubuntu 13.10 64bit.
Update: I am trying to chroot from liveUSB, but I am getting:
chroot: failed to run command /bin/bash: No such file or directory
How to fix it?
