Upcoming Ubuntu 25.04 changed the way default terminal is launched.

Hi guys.

I just installed 25.04 beta and setting x-terminal-emulator doesn't work anymore to launch Ghostty or any other non default terminal in Gnome 48.

New Gnome doesn't use system-wide x-terminal-emulator and uses ~/.config/xdg-terminals.list instead for every user, and in case of Ubuntu it's ~/.config/ubuntu-xdg-terminals.list

To launch ghostty with ctrl+alt+t shortcut you need to set :

com.mitchellh.ghostty.desktop

in ~/.config/ubuntu-xdg-terminals.list

Possible changes to Gnome and Ubuntu are discussed in https://bugs.launchpad.net/ubuntu/+source/xdg-terminal-exec/+bug/2107326
with additional links to proposed Gnome changes etc.

Converted to a discussion. As far as I can tell, there's nothing the Ghostty package needs to change to deal with this, users will just need to follow the Gnome instructions for setting up xdg-terminal-exec correctly.

Yep, just wanted to inform people as they may come to ask for fixes.
