Steps to set Terminator as the default terminal on Ubuntu
Estimated reading time: 4 minutes
This tutorial is not just limited to Ubuntu systems. We can use it for Linux Mint, Debian, POP OS, Elementary, Zorin OS, and more…
Run command terminal
Open any installed command terminal on your Ubuntu Linux. It is because here in this tutorial we are going to use the command line to configure the default application. You can use the Ctlr+Alt+T keyboard shortcut.
Change the default terminal on Ubuntu to Terminator
Well, to change the default Ubuntu Terminal and set some other, we need to have at least one more Terminal emulator app apart from the one which comes with the system. For example, Ubuntu offers Gnome Terminal but now you have installed the Terminator and want any of them set as the default one. In such cases, an inbuilt utility of our Linux system, called update-alternatives can be used. We can use this utility to switch between the installed Terminal applications on our system to make any of them the default one. It is not limited to the terminal apps, we can use it for browsers and other applications as well. It is because this utility is responsible for setting up default applications in Ubuntu or Debian. Run the given command to change and select the default Ubuntu or Debian Terminal.
sudo update-alternatives --config x-terminal-emulator
As you run the above command, you will get the list of all existing Terminal-emulators with a provision to select any of them. For example:
There are 7 choices for the alternative x-terminal-emulator
(providing /usr/bin/x-terminal-emulator).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/bin/alacritty 50 auto mode
1 /usr/bin/alacritty 50 manual mode
* 2 /usr/bin/gnome-terminal.wrapper 40 manual mode
3 /usr/bin/koi8rxterm 20 manual mode
4 /usr/bin/lxterm 30 manual mode
5 /usr/bin/terminator 50 manual mode
6 /usr/bin/uxterm 20 manual mode
7 /usr/bin/xterm 20 manual mode
Press to keep the current choice[*], or type selection number:
What you have to do, is first find the “Selection” number of the Terminal that you want to set as the default one. After that type it and hit the Enter key. And you are done. For example, to set Terminator, we type – 5 and then press the Enter key. In the same way, use the Selection number assigned to Terminator on your Ubuntu 20.04 or 22.04 system.
Check whether Terminator is set as the default terminal or not
Once you are done with the previous steps, it’s time to check whether the default Terminal has been changed and set to the new one or not. For that, run the same command above given again but this time you will see the Asterik (*) in front of the Terminal you have selected. This shows the changes are done, successfully.

In the same way, we can change and set any terminal on Ubuntu 20.04 or 22.04 as the default one using the update-alternatives utility. If you have questions, the comment section is all yours.
