Had new installation of Ubuntu-Gnome then add Unity via:
sudo apt-get install ubuntu-desktop
Now I have all this shells at log-in screen
- System Default
- Gnome
- Gnome Classic
- Ubuntu
I am trying to tune this OS while keeping one Unity and one Gnome:
$ uname -a
3.16.0-31-generic #41~14.04.1-Ubuntu SMP Wed Feb 11 19:30:13 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
$ gnome-shell --version
GNOME Shell 3.10.4
What is the best way to do that? i.e purge the two extra shells.
