Currently have Ubuntu 15.04 with the default Unity desktop environment. I wanted to try the Gnome environment so I followed the following instructions:
Install GNOME Desktop Ubuntu 15.04
However, no there are a number of bugs that affect my Unity environment. For instance, I cannot change my wallpaper from the default one -- right clicking, Unity Tweak Tool, and CCSM do not work. Also the Super key works intermittently. There are also still options on the login screen to select the Gnome environments.
What is the best way to remove Gnome and start from scratch? I've so far tried
sudo apt purge gnome-shell
The script ran but these issues are still apparent after restarting.
Any help would be appreciated.
