None of the handful of different wayland implementations have managed to support any of the network based keyboard/mouse sharing programs like synergy/barrier/input-leap (and vice versa). This lack of functionality is a real dealbreaker for me.

Okay. I use hardware solution for that, so wasn’t aware of issues. is it related to issues with evdev?

(my hardware solution is logitech mx keys & their mouse, pair up to 3 machines at once)

Wait, does this work on Linux with wayland?

Why wouldn't it? It's hardware; it sends the inputs to the machine you tell it to, regardless of whether that machine is running X11 on Linux, Wayland on Linux, or Windows 3.11 on DOS.

Wait, not even a Wayland version of x2vnc? That wouldn't take much, surely?

I have 4 computers and 7 monitors in my keyboard/mouse sharing span. Nothing vnc* is going to do it.

Well, I meant wayland-wayland, not wayland thru Xwayland. I'll keep Xwayland, and those horrible 748397438924 client libs (yeah wayland code is static/private to distributed binaries), for games still missing a wayland backend (with unity/unreal5.x/godot/etc and via libSDL[23], I wonder if that exists on modern elf/linux games unless a custom engine).

But it seems the really hard part for valve is dropping their 32bits legacy code which is hardcoded for x11 and opengl... they are adamant at keeping it.
