Gnome-kiosk-search-appliance hangs at login in Ubuntu 24.04

[Pauli Heikkinen]

1. Install Ubuntu 24.04.
2. Sudo apt-get update.
3. Sudo apt-get upgrade.
4. Sudo apt install gnome-kiosk.
5. Reboot.
6. Log in, choosing the Gnome Kiosk Search Appliance session.

Expected result:
----------------

User session begins with Firefox displaying the search site (currently Google) in a full screen windows in kiosk mode.

What actually happens:
----------------------

In a physical computer I just got a black screen that doesn't appear to react to anything except Ctrl+Alt+Del.

In a VirtualBox VM gdm just hanged when login should have happened. Sending ACPI shutdown still shut down the VM though.

Gnome Kiosk Script Session works.

I thought I almost got this working but nope:

* I made a systemd gnome-session target.d folder and specifying per session requirements there (just like the script session already does)
* It would start a session but it wouldn't start Firefox, so I created an org.gnome.Kiosk.SearchApp.service file in /user/lib/systemd/user. Wrote the exec command so that it starts an sh script that first runs Firefox and when that process exits it calls gnome-session-quite --no-prompt. That got Firefox started, but also displayed an error dialog saying that Firefox is already running...
* ...so I then removed the requirement for the search app .desktop file from the Gnome session file in /usr/share/gnome-session/sessions. But after that I was back to Firefox not starting.

So if I use both the .desktop file and a custom systemd .service file, Firefox starts twice, but if I don't use either, it doesn't start at all. I just can't make sense of how all of this is supposed to work.

Sorry, meant to write that if I only use one or the other, obviously if I don't use either nothing happens :)
