Ubuntu has switched to Unity, but I am not used to Unity. On the contrary, I like Gnome3 very much. In fact, on Ubuntu, Unity and Gnome3 can coexist completely. However, since Unity is not used and it still needs to be updated, simply delete it. After checking some information, the deletion method is summarized as follows:

1. Make sure that automatic logon is not set for Unbutu before deletion.

2. Install Gnome3:

Sudo apt-get installgnome-shell

Sudo apt-get installgnome-tweak-tool

3. Set the Default Login desktop environment:

Log on to gnome shellclassic:

Sudo/usr/lib/lightdm-set-defaults-s gnome-classic

If you like GNOME3

Sudo/usr/lib/lightdm-set-defaults-s gnome-shell

4. Delete Unity:

Sudo apt-get-y -- auto-remove purge unity

Sudo apt-get-y -- auto-remove purge unity-commonp

Sudo apt-get-y -- auto-remove purge unity-lens *

Sudo apt-get-y -- auto-remove purge unity-services

Sudo apt-get-y -- auto-remove purge unity-asset-pool

### Note: sudo apt-get -- auto-removepurge unity * cannot be used. Check that there are many

UNITY-independent items are also listed.

And unity-greeter must be retained. If you delete it, you can find a solution by squatting on the wall and crying for a while.

5. log out and log on again.

In this way, you can use the cute Gnome3.
