Hi, thanks for your work on lan-mouse!

I'm trying to use it on Wayland with xdg-desktop-portal and a desktop (Gnome) that supports InputCapture However, I get this error in the journal when trying to use lan-mouse:

A backend call failed: No such interface “org.freedesktop.impl.portal.InputCapture” on object at path /org/freedesktop/portal/desktop

Checking the DBus interfaces, I have a org.freedesktop.porta.InputCapture interface at /org/freedesktop/portal/desktop rather than org.freedesktop.impl.portal.InputCapture.

Is there an issue in my portal configuration, or is it trying to call the wrong interface?

Yeah, the issue was in my configuration.
I had the GDK_BACKEND env var set to "wayland,x11"

Gnome portal seems to not like this, giving the following error:

GDK backend forced via env var, portal dialogs will not work properly.
Non-compatible display server, exposing settings only.
