Sorry if this question is already answered, but I have already searched and could not find a solution to my problem.
Recently I installed gnome-shell and ubuntu-gnome-desktop to try gnome. I then removed it using
sudo apt-get remove gnome-shell ubuntu-gnome-desktop.
From that moment I couldn't change my desktop wallpaper. Also, when I right click on my desktop it doesn't work.
I read in some links to check if xfdesktop is running…
In my ubuntu, that process is not running.
When I run xfdesktop from terminal, it gives me the following error:
SESSION_MANAGER environment variable is not defined. Failed to connect to session manager.
I don't know if it has any relation to my problem.
Another thing I observed is that gnome-system-monitor and gnome-session are still running on my ubuntu… why are they running if I want Unity only?
Is there any way to reset my ubuntu to as it was initially. But I have also installed some useful applications and packages in this, can I keep them even after resetting?
Thank you in advance!
