KDE Connect - Extend Display

Brainstorm
,
1

A feature, most modern cross device tooling has, is that you can just use one device as an extra screen of another one.
I would love to see this, so that I could just use my home desktop pc with its screens, as extra screens on my work notebook, without having to completely rewire everything every time.

Android to Linux is doable with scrcpy or Screencasting , but it will require high bandwidth and stable connection.
It would be a novelty feature if we get it at all.

Yes i know bout screencopy, but this is about extending Display between PCs

I think it would be a good feature, I’m just wondering how many people needs it. it’s a pretty specific feature and I think it requires a big effort to be developed

Actually, it looks like it already partially exists in KDE Connect.

And for the People needing this:

  • People having a notebook they want to use as an extra screen (because hardware is not cheap) for their home PC
  • People wanting to use the screens of their home PC with their laptop (hot workstation like, not everybody can pay for Thunderbolt on everything)

There is a reason Apple and Windows support this

A use case that I can add is using an android tablet as a graphic tablet. I would (my wife a lot more) love it

There are better existing tools than KDE Connect to do that sort of thing, though, if you’re talking about PC-PC linking/sharing.

(Although most of the ones I know about don’t work on Wayland, which highlights another problem: if you want to extend your desktop’s screen to another device, that support has to be built into the OS at a fairly low level. You need a privileged extension of the desktop environment, not just a random app. In the days of X11, any random program could do whatever it wanted with your system’s display, but that kind of thing doesn’t really fly anymore.)

Doesn’t KDE Plasma as Compositor, have all the permissions needed for the feature, so it could have an API used by KDE Connect?
(Or even Better, make such an API into an XDG Protocol, like the Screnshare one)

Think you’re looking for Deskreen.
