            Bug ID: 523735
           Summary: Allow starting headless session without physical
                    display
    Classification: Plasma
           Product: kwin
      Version First unspecified
       Reported In:
          Platform: Arch Linux
                OS: Linux
            Status: REPORTED
          Severity: wishlist
          Priority: NOR
         Component: wayland-generic
          Assignee: [email protected]

  Target Milestone: ---

DESCRIPTION
There are ways to create virtual displays from within an already running
session, but no way seems to exist for starting a fresh KWin headless (Wayland)
session without any physical displays attached.
At least there is currently no documentation for doing that, so I assume it is
not yet doable.

An ideal implementation would require starting a headless Wayland session and
sharing the framebuffer and accepting inputs through a local socket, so that an
external tool can use that socket to provide access to the session however it
likes. Using a socket-based system will allow it to be protocol-agnostic (no
VNC or RDP support at the lower level, only streaming raw framebuffers).
The implementation should also support multiple virtual outputs with dynamic
output setting changes.
