How can I restart my GUI (X window server) from command line without rebooting the system? Which process(es) do I need to kill and do they automatically restart?

All you need to do is restart LightDM as root, like so:

sudo restart lightdm
  • You should probably mention that you should do this from a TTY (virtual terminal). – RolandiXor Sep 16 '16 at 17:19
  • I was guessing from the level of detail of the question that Mr. Wolf knows his way around the terminal. :) – Fred Rocha Sep 16 '16 at 18:15
  • I wasn't just referring to the "terminal", but oh well. (I said virtual for a reason. I mean the thing you get when you press ctrl+alt+f-key-of-your-choice). – RolandiXor Sep 17 '16 at 22:30
  • Oh, I see. And what would the advantage be in this case? How would that work? Curious myself now. :) – Fred Rocha Sep 18 '16 at 12:35

This worked for me:

sudo service lightdm restart
