Disabling the Guest Session in Ubuntu

on ubuntu

In this short tutorial, I’ll show you how to hide the Guest Session from the LightDM login screen on Ubuntu. This is something that I do every time I install a fresh copy of Ubuntu. Hopefully, there will be a button for that in the future.

Edit /etc/lightdm/lightdm.conf:

$ sudo nano /etc/lightdm/lightdm.conf

Insert this line:

allow-guest=false

Just restart Ubuntu for changes to take effect.
