For those who want to install the latest Tilix terminal emulator 1.9.5 in Ubuntu 22.04 LTS. You can now get it from PPA repository.

Tilix is a popular tiling terminal emulator, that allows to split terminal window horizontally and/or vertically, and drag and drop re-arrange them. It also has many other great features including sync input between terminals, background images, quake mode (drop-down terminal), and custom hyperlinks.

The terminal emulator package is available in Ubuntu repository, but old. Though, the latest v1.9.5 has been released for 5 months. Changes in Tilix 1.9.5 include:

  • Disable advanced paste when there is no linebreak like iTerm2
  • Add environment variable when in quake mode
  • Add possibility to configure always enabled regex
  • And various bug-fixes.

1. Add PPA

The unofficial PPA so far contains the latest package for Ubuntu 22.04 only. Due to dependency issue, it does not build in Ubuntu 20.04.

To add the PPA, press Ctrl+Alt+T on keyboard to open terminal and run command:

sudo add-apt-repository ppa:ubuntuhandbook1/tilix

2. Update package cache

Ubuntu now automatically refresh the package cache while adding PPA. But, you have to run apt update command manually in some derivatives, e.g., Linux Mint.

sudo apt update

3. Install Tilix

Finally, install the software package by running command in terminal:

sudo apt install tilix

After installation, search for and open Tilix either from start menu or by searching from ‘Activities’ overview, depends on which DE you have.

How to Uninstall:

For any issue, you can install ppa-purge and use the tool to purge PPA. Which will also downgrade all installed packages from that PPA to the stock version in your Ubuntu:

sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntuhandbook1/tilix

And if you need to terminal emulator any more, remove it either from Ubuntu Software or by running command in terminal:

sudo apt remove --autoremove tilix tilix-common

This simple tutorial shows how to change the default terminal emulator from Gnome Terminal to the one that you prefer in Ubuntu.

The default Gnome Terminal is great, but there are many good alternatives (e.g., tilix). If you prefer to use another one and want to set it as default, so you may press Ctrl+Alt+T to open it.

Step 1: Create symbolic link to x-terminal-emulator

Ubuntu seems default to x-terminal-emulator, which is a virtual package by default links to Gnome Terminal.

By creating a group of alternatives to the package allows to switch which one to use at any time with a single command.

Firstly, open terminal and run command to create a symbolic link (replace /usr/bin/tilix with your terminal emulator):

sudo update-alternatives --install /usr/bin/x-terminal-emulator x-terminal-emulator /usr/bin/tilix 1

Some terminal emulators may already created the symbolic link automatically after installation, so you can just skip this step.

Step 2: Select your terminal to use as default:

Next, run the command below will output all available alternatives:

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

Type the number for the one that you prefer and hit Enter will set it as default terminal.

In the case, I selected 5: ‘/usr/bin/tilix.wrapper’. It’s a Tilix wrapper with command line arguments that created automatically during installation. Step 1,

Restore and remove the alternative link:

To revert back to Gnome Terminal, just re-run the command in Step 2 and choose number 0 or 1.

And to remove the link created via Step 1, use command (replace ‘/usr/bin/tilix’ accordingly):

sudo update-alternatives --remove x-terminal-emulator /usr/bin/tilix

That’s all. Enjoy!
