Not possible to select Screen Sharing on RustDesk 1.2.4

[thepragmaticmero]

System Information

• niri version: 0.1.6

• Distro: Fedora Immutable 40

• GPU: Intel Graphics

• CPU: N2840 Intel

I tested RustDesk experimental screen sharing on Gnome and KDE and in the current version it works, but not on niri... I don't know why, I also tested OBS-studiio on niri and it works, but RustDesk doesn't. Why could be that?. Some shenanigans about xdg-desktop-portal? The popup appears on Gnome and KDE tho... I'm pretty confused.

Also as a curiosity where could I consult the "Always remember this selection" list? If I for example wanted to see all the programs that I previously gave permission to use my screen on wayland. Gnome makes automatic use of it with it's gnome-remote-desktop service.... how did the gnome team manage to 'inject' the "remember this selection" by default with that program?

Could you post niri output? journalctl --no-hostname -eb /usr/bin/niri

Weird, I don't see any screencast start attempts in the first log. Maybe it uses a different portal (remote desktop?) that niri doesn't yet implement.

[thepragmaticmero]

As I said, it works fine on xdg-desktop-portal-kde and xdg-desktop-portal-gnome (Gnome and KDE), I tested them rebooting every time and accessing them via gdm/sddm and yet the only one that doesn't work is with Niri O-O. Weird huh, could you replicate it?. Maybe some other bugs could be solved by fixing this.

• Tested using Flatpak version of RustDesk

As I said, it works fine on xdg-desktop-portal-kde and xdg-desktop-portal-gnome (Gnome and KDE),

I mean, if niri doesn't implement the remote desktop backend, then there's nothing xdp-gnome can do but return an error. It might show up in RustDesk's logs or xdp-gnome's logs.
