I installed Mate desktop environment in Ubuntu 18.04 as described in the this blog.
The following commands -
$ sudo apt install tasksel $ sudo apt update $ sudo tasksel install ubuntu-mate-desktop
But I didn't like Mate therefore I tried to uninstall it -
sudo dpkg-reconfigure gdm3
But above command did not uninstall Mate environment completely.
How to remove Mate completely from Ubuntu 18.04?
