I Just installed gnome-shell in my 12.04 box and, unity disappears from the login screen.
This is what I've done trying to fix:
- #Exec: unity --reset`
- Purge and install: indicator-session
- Set Display full username to true in gsettings
`
Try this:
Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command below.
sudo apt-get install --reinstall ubuntu-desktop
If you have compizConfig Setting Manager installed then try
ccsm
If you were using compizconfig-settings-manager and messed up your desktop. Only thing that worked successfully for me, was repair it with the same program..
ccsm (To start program.)All other stuff what you can find online, such as
sudo apt-get install --reinstall ubuntu-desktop
haven't give any result. It was just waste of time.
