The input sidecars (shepherd-touch-bridge, shepherd-gamepad-bridge; triggered by input_compat in the config) are so useful on a gaming handheld that I genuinely miss them when it is running a regular desktop session.

Unfortunately, they are currently written to require wlroots compositors, of which Ubuntu's default GNOME is not:

Error: compositor does not support zwlr_virtual_pointer_v1 (a wlroots-only protocol); the bridge requires a wlroots compositor such as Sway. If you're running this standalone, launch it from inside the shepherd-launcher Sway session (or `./run-dev`), not from your desktop's Wayland session (KWin/Mutter/etc.)

The sidecars should be rewritten to work on any Wayland, not just wlroots.
