How do I change the default session for when using auto-logins?

Every time I restart my computer it auto-logs me into the Unity desktop, is there some way to make Gnome the default choice, I hate having to log out every time and switch to it.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Your preferred desktop should be remembered automatically. If it doesn't, it's a bug. Report it on Launchpad.net. In the future, please try to provide information about what version of Ubuntu you're using. It makes things easier. – Jo-Erlend Schinstad Feb 11 '12 at 19:10
  • Disable auto login, then choose to log into the Gnome session upon reboot, Gnome will be the default as it was your previous session. – Uri Herrera Feb 11 '12 at 19:11

To make Ubuntu 11.10 auto log-in gnome-shell, open up a terminal window and run this command:

sudo /usr/lib/lightdm/lightdm-set-defaults -s gnome-shell

If you want to change back to Unity, run:

sudo /usr/lib/lightdm/lightdm-set-defaults -s ubuntu

gksu gedit /etc/lightdm/lightdm.conf and you will see something similar to


just change the session and save
