Switch Between Window Managers On Debian Mate Using GUI/CLI

Share:


What is a Window Manager?
In general, window manager or WM is the system software that draws the appearance and handles the placement of windows on a GUI based desktop environment. Window managers controls the window borders, resizing, title bar and even provide effects/animations. WM can be a part of a desktop environment or can be used independently.

Why to switch another WM on Debian Mate?
If you are trying to switch to another WM you probably have already a reason. But for starters, the default WM on Mate, Marco, is very basic and not much customizable. There is absolutely no effects/animations tweak. Now if you ask me why you even want animations on Debian, well then that's another story.
This tutorial is specific for Debian Mate but not strictly. That means you can use this same method to switch WM on any distros with Mate desktop environment.

Switching Window Manager On Mate

There are two methods detailed on this article to switch window managers. First one is using Mate Tweak Tool which lists all available/installed window managers. And the other one is using dconf editor, you will have to enter the window manager's name manually to switch to it.
To install Mate tweak tool, enter the following commands on terminal.
For Debian
sudo apt install mate-tweak

For Ubuntu, Mint
sudo add-apt-repository ppa:ubuntu-mate-dev/ppa
sudo apt-get update
sudo apt-get install mate-tweak

For other distro: https://github.com/ubuntu-mate/mate-tweak

After installation, run the tool from menu or type mate-tweak on terminal.
Now from the windows section on mate tool, you should be able to switch between window managers instantly without any reboots or logouts, but i really recommend rebooting your system once. See the pic below for more detail.




Now the second method is using gsettings from terminal, or you can use dconf editor if you prefer. So as i have already told, you will have to manually set the name of your new window manager. Open terminal and type the following command.
# replace wm-name with your new window manager, that could be compiz, kwin, openbox etc
gsettings set org.mate.session.required-components windowmanager wm-name
To go to default window manager,
gsettings set org.mate.session.required-components windowmanager
And this way you should able to change/switch default window manager on you Mate DE. But be careful,  Anything can go wrong while switching to another window manger, you might end up switching to an unsupported window manager rendering your system useless. Just like all the time, got any issue?? Just comment down below. ENJOY YOUR DAY..
