This may or may not be worth mentioning but the reason I totally purged lightdm was just using dpkg to change to gdm3 returns an error:
lance@lance-conroe:~$ sudo dpkg-reconfigure gdm3 [sudo] password for lance: gdm.service is not active, cannot reload. invoke-rc.d: initscript gdm3, action "reload" failed. Of course I could also have run sudo dpkg-reconfigure lightdm and accomplished the same thing. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/1749481 Title: Wrong session marked as selected in session dropdown on login screen Status in gdm: Invalid Status in gdm3 package in Ubuntu: Incomplete Status in gnome-session package in Ubuntu: Incomplete Bug description: My usual session is "Ubuntu" (/usr/share/xsessions/ubuntu.desktop). When I reboot my machine, on the login screen if I click the cog icon to show the list of sessions available, a dot is displayed to the left of the first session in the list ("GNOME"), instead of "Ubuntu". If I don't click on a session to change it, when I log in the session used is "Ubuntu" as expected, not "GNOME". So the greeter fails to reflect which session is actually selected when first displaying the dropdown, but internally it doesn't mess up with session selection.
