--- Comment #6 from Stefan Hoffmeister <stefan.hoffmeis...@econos.de> --- >From the implementation, I cannot tell how the framebuffer(?) backing the ouput(?) ever gets removed. Basically, as part of the change sequence, the second screen goes into !isConnected with resolution 1280x800, and the current implementation still tries to talk to "it" (connector/output). This fails on various DRM calls: ``` Dec 13 18:24:43 fedora kwin_wayland[3945]: kwin_wayland_drm: Connection on "Virtual-2-unknown" is in state 2 ?libkwin.so.6?|?libkwin.so.6?|KWin::DrmBackend::updateOutputs|KWin::DrmBackend::handleUdevEvent|?libQt6Core.so.6?
