I know that remote desktops are still a moving target in Wayland. Out of curiosity I tried to access a remote desktop running in an up-to-date Tumbleweed system. I selected to start with what I had been using successfully previously. This message is just a status report on my use. And a request for suggestions as to how best to proceed.

I always have this set up so the main desktop is shared. We mainly use this doing support.

I use x11vnc on the remote desktop, with this command that starts when I access port 5900 (via an entry in xinetd):
/usr/bin/x11vnc -inetd -rfbauth /etc/vncpasswd \
-o /var/log/x11vnc.log -display :0 \
-auth /run/sddm/{*-*-*-*-*} -env FD_XDM=1 \
-shared -forever
My client command is:

vncviewer -passwd /home/roger/.vncpasswd stingray:0

where stingray is the system sharing the desktop. I use x11vnc -storepasswd on the server, and vncpasswd on the client to manage the password.

Prior to the update to KDE6, this had been working. I suspect that the change to Wayland in the update has broken things. I expected that.

It is not a total failure. When I connect, the password and other things still work. I get a window that is the expected size (a laptop with an external display sized window). Unfortunately the window contents are fully black. Moving the mouse or pressing a key does not make a change.

I suspect that I need to move away from X (x11vnc after all) and start investigating Wayland compatible solutions. Are there any? Especially ones that work as I am - share the existing desktop?

Other than this and the odd decision of KDE to no longer disable a touchpad when a mouse is connected, KDE6/Wayland seems to be working fine for my uses.
