Comment 1 for bug 1463116

I have this problem after upgrading to Lubuntu 15.04 32bit.

"The system will not start the GUI, I land in emergency mode which says "Error getting authority: Error initializing authority: Could not connect: No such file or directory (g-io-error-quark, 1)" and suggests to ^D to attempt to boot into default mode."

When I press ^D it just says the same thing again. After pressing it a few times, it starts to ignore keyboard input (numlock led changes, but caps lock does not).

"sudo systemctl enable lightdm" gives the same output, but with some lines of "Error getting authority: Error initializing authority: Could not connect: No such file or directory (g-io-error-quark, 1)" mixed in and also does not solve the problem.

However, if I choose to boot with upstart instead, under advaced boot options, everthing (including lighdm) works fine.
