From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Wayland support, would you look at that!
Was it rustdesk or some other popular open source remote desktop software that had "no plans of supporting wayland"? In any case, nice!
Just a beta feature though. Last time I checked it still didn't work unattended. So unless the missing wayland puzzle pieces are in place now, it's likely still unusable for be.
That is also a wayland showstopper for me personally. Does someone know if it is a per se wayland issue or is there "only" the implementation missing (i.e. in plasma wayland for instance)?
Wayland is all about protocols being implemented by the DEs. So far there is (afaik) not a fitting protocol for remote desktop usecases.
Even screensharing is still a PITA, since the desktop portals work independantly from the requesting application. App asks portal "what apps and screens are there?", then the user gets prompted by the portal to select the allowed entities. Then the application lists these again, user picks it again, and then gets prompted by the portal again to basically confirm that you really want to share it. That's mostly a discrepency between how the apps work (on X11, Windows and OSX vs Wayland). But it's in the end still a pain for the user.
Grabbing and manipulating inputs is another matter. Allowing that globally is a security issue, so Wayland doesn't do it. But remote desktop needs that. So now there needs to be a standard protocol that the DEs implement to allow remote desktop solutions to access inputs. Or they do it like RustDesk, run as root and intercept inputs before wayland gets a chance to intervene.
Thanks for the insights. Than I might try RustDesk again, and see if they successfully worked around the wayland shortcomings.
Yeah, screensharing is not optimally either, but at least it is working. I mean I could live with a portal which operates like for example a file chooser, but than it should implement the whole process of choosing a window or a screen without any further interaction necesary in the parent application.
