I installed Unity desktop on ElementaryOS but after it caused slowness I decided to remove it. I saw this post on Askubuntu.com:

sudo apt-get remove unity

sudo apt-get remove lightdm

sudo apt-get remove ubuntu-desktop

Unfortunately, after these commands I reboot and my log in screen disappeared with a black screen. How can I resolve that? And what caused this to happen?


If I recall correctly, you should be able to press Ctrl+Alt+F2 and login with your username/password, then run sudo dpkg-reconfigure pantheon-greeter to do this.

  • You're very welcome. Glad it's fixed!
