When I logged in after reboot I had no gnome-panel. When I tried ctrl-alt-delete and ctrl-alt-t they did nothing. I started gnome-panel manually via nautilus.
This is probably what screwed my computers:
Changes for gnome-session-flashback versions:
Installed version: 1:3.6.2-0ubuntu13
Available version: 1:3.6.2-0ubuntu14
- Set DesktopName and X-LightDM-DesktopName to Unity instead of GNOME
since Flashback uses indicators and the same "fallback" components
Unity does. This will also allow for a more consistent experience
for Edubuntu which offers both Unity and Flashback.
