Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I recently installed Gnome 3.8 to play around with it. I thought it would only add it to my session manager, but it also made it default and began using the GDM instead of LightDM.

Then, things got strange. When I tried to load Unity, it gave me a error in a window (not command-line):

Failed to load system 'Ubuntu'.

Then gave only one option: "Log Out."

I can by pass this by opening Gnome as normal and running


in the terminal, but when it loads it has no status icons (such as battery, network, etc.) in the top bar.

If the only way to fix this is to somehow add those icons back, that is acceptable, but can I somehow fix the Unity load issue?

Thank you.

You might try opening a terminal CTRL+ALT+T and switch back to light-dm using "sudo dpkg-reconfigure gdm", then selecting light-dm as your default window manager. –  DrA7 Aug 11 '13 at 7:40
That helped, but it still gives the same error upon loading Unity. –  Ben Ayers Aug 11 '13 at 14:41
You could try reinstalling unity? –  DrA7 Aug 18 '13 at 7:24
