Please advice how to properly install Gnome Flashback DE on Ubuntu 14.04 (that comes with Unity by default). I want keep all application that was preinstalled with Unity DE: LibreOffice Writer, Calc, Impress, etc. Should I only run:

sudo apt-get update
sudo apt install gnome-session-flashback

Should I uninstall Unity first? Or after installation of Gnome Flashback? There is no need to have two Desktop Environment installed.


Just install GNOME Flashback session and use it.

There is no need to uninstall Unity. For example GNOME Flashback in Ubuntu use unity-settings-deamon, so trying uninstall whole Unity might uninstall Flashback session too.

  • I think I should install gnome-panel, not the full gnome-session-flashback: is that corrrect? – minto Jul 29 '16 at 11:58
  • Depends on what you want... gnome-panel only will not be enough, you will not be able to select Flashback session in login screen. – muktupavels Jul 29 '16 at 14:08
  • I mean, gnome-panel is gnome-fallback, and only includes the metacity window manager and not Compiz, and therefore no Unity either. If I have default ubuntu-desktop package installed, then I have installed also Unity and Compiz packages, which the fallback session would be able to use. So if I install gnome-panel I should be able to get just the fallback session? – minto Jul 29 '16 at 20:05
  • gnome-panel package is not enough to get fallback session unless it depends on needed packages which it should not. gnome-panel just gives you panel, few applets and nothing more. Install gnome-session-flashback. – muktupavels Aug 16 '16 at 20:49
