Bug ID: 454645
Summary: Wishlist: support for adding headless outputs - iPad
as second screen using VNC or RDP - like Gnome and
Sway
Product: kwin
Version: 5.24.5
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: philipp.reichm...@gmail.com
Target Milestone: ---
I want to repurpose some old tablets as secondary displays. They're slow, but
fast enough to run a VNC or RDP client. If I could set up some virtual/headless
outputs that are accessible via VNC or RDP, I would find it very useful,
because I could use any old tablet to extend my screen real estate.
Gnome and Sway can already do this, and so can KWin with X11:
- Sway has had an option to configure headless outputs since 2020, you can then
run a VNC server on those outputs:

- Gnome has support for virtual monitors via RDP since Gnome 42, support was
merged a few months ago:

- With KWin X11 I used to be able to achieve this in a hackish way by setting
up a virtual output in XRandR, similar to this:
