While Ubuntu uses the default terminal emulator for the particular flavor you’ve chosen (such as Terminal for the stock GNOME desktop), there are several reasons you might want to change it.

You may be used to a particular terminal editor from another distro or desktop environment. A lot of programs on Linux predate Linux itself, and that includes several popular terminal emulators on Linux. Some of the terminal programs you’ll see later are quite old but still have many loyal users and developers.

Just as some people enjoy distro-hopping, it can be fun to try out new application programs, especially with the wide array of choices you have in modern Linux distros. A new terminal is only a click or an apt command away. Some of the features are useful while others are just plain fun. Having a terminal seem  to slide down from the top of the screen or emulate an old CRT screen adds some visual flair to your Linux experience. Who doesn’t like to pretend to be a hacker in a ’90s movie?

One of the best ways to find a new terminal program to try is to use the Ubuntu package manager. You might try searching for “terminal emulator” or “terminal.” You could use “apt search”, the online Ubuntu package browser, or the Software Center.

Some Good Choices

1. urxvt

Screenshot by David Delony — no attribution needed.

urxvt, a variant of rxvt, was originally written as a replacement for the xterm program that ships by default with the standard X11 installation on Linux systems. urxvt was intended as a lighter-weight alternative because it omits a lot of the emulation of specific terminal models because dedicated terminals are obsolete. urxvt supports Unicode, hence the “u” in the name.

To install urxvt on Ubuntu, use this command:

sudo apt install rxvt-unicode

2. Eterm

Eterm is a project to develop a terminal emulator for the Enlightenment window manager/desktop environment. While it’s serviceable, the project itself has been largely inactive, even as the broader Enlightenment desktop continues to be developed.

If you want to install it, use this command:

sudo apt install eterm

3. cool-retro-term

cool-retro-term may not be a practical choice for day-to-day work, but it sure is fun to use. The program emulates the look of a CRT character terminal. This was the experience in the ’70s, ’80s, and even the ’90s before graphical interfaces were widely used on Unix-like systems. As someone who grew up using CRT monitors with the eyestrain to prove it, I like this one a lot.

To install cool-retro-term, use this command:

sudo apt install cool-retro-term

4. Guake/Yakuake

These terminal emulators use a drop-down menu that, as the names suggest, is inspired by the consoles in first-person shooter games, particularly the “Quake” series.

To install Guake, use this command:

sudo apt install guake

And to install Yakuake:

sudo apt install yakuake 

5. Terminator

Terminator is a cool terminal emulator that lets you have multiple terminals in the same window, similar to how you can do so using tmux or Gnu Screen session. You won’t be able to suspend and restore sessions. When you close a window, it’s gone.

To install it, use this command:

sudo apt install terminator

How to Change the Default Terminal

When you’ve chosen the terminal you want to use, you can set it up as the default when you have a program that opens up a terminal window. To do this, open up a terminal window and type:

sudo update-alternatives --config -x-terminal-emulator

Enter your root password, and you’ll be presented with a menu showing the terminal emulators you have installed on your Ubuntu system. Type the number of the terminal program you want to use, and then press Enter.
