Default terminal

For GNOME Users: Setting the default terminal through gsettings

gsettings set org.gnome.desktop.default-applications.terminal exec '/usr/bin/terminator'

Using update-alternatives

This method updates the system’s alternatives to set a new default terminal emulator.

sudo update-alternatives --install /usr/bin/x-terminal-emulator x-terminal-emulator /usr/bin/terminator 50

This command installs Terminator as an option for the default terminal emulator within the alternatives system, assigning it a priority of 50. Higher priority numbers give the terminal higher precedence during the automatic selection process.

sudo update-alternatives --list x-terminal-emulator

This command lists all the terminal emulators that are registered within the alternatives system. It allows you to verify that Terminator is correctly installed and shows other available options.

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