I just used Synaptic to install MATE Desktop Environment on my Ubuntu 14.04 computer. It installed successfully, but after rebooting, it's not showing up on the login screen. My only options are to choose from Ubuntu (Default) or XFCE. Does anyone know why and how do I get MATE to work?
Open a terminal and run:
sudo apt-get remove --purge mate-desktop sudo apt-get autoremove
now add the MATE Official repo, press
y when prompted.
sudo apt-add-repository "deb http://repo.mate-desktop.org/archive/1.8/ubuntu trusty main" sudo apt-get update
then install it:
sudo apt-get install mate-core sudo apt-get install mate-desktop-environment sudo apt-get install mate-desktop-environment-extra sudo reboot
Now you should be able to see
MATE at the login screen.
Previous answer is not totally correct. It installs Vanilla MATE, not Ubuntu MATE.
Follow the instructions on install page of MATE desktop project:
sudo apt-add-repository ppa:ubuntu-mate-dev/ppa sudo apt-add-repository ppa:ubuntu-mate-dev/trusty-mate sudo apt-get install ubuntu-mate-core ubuntu-mate-desktop
For Ubuntu versions later than 14.04 just simply install these packages, not adding reps (they are already in ubuntu reps).
