Scenario 1:
Ubuntu installs GNOME3, there is an easy way to install the Ubuntu gnome distribution directly. The following is the original 16.04.02LTS based on the installation of the GNOME3 desktop environment. sudo apt-get install gnome-shellsudo apt-get install ubuntu-gnome-Desktop It's worth noting that you remember to install gnome- When the shell chooses that GDM, otherwise the boot default is unitysudo apt-get install unity-tweak-toolsudo apt-get install gnome-tweak-tool
Restart
------------------------------------------------------------------------------
Scenario 2:
Apt-getupdate
Apt-getGnome-session-flashback
This option switches between unity and GNOME, but feels gnome is a bit more sketchy.
