--- Comment #1 from Jean-Sébastien Guay <[email protected]> --- Additionally, I just found out, in this state (after connecting to the host and disconnecting), if I go to the host physically and try to restart the krdp service, it crashes with the same "Failed to create wl_display (No such file or directory)" error I mentioned when running kscreen-doctor through ssh. I found out because I wanted to disable exclusive mode for now until this issue is fixed, and the server crashed on restart after applying the change. Weirdly, kscreen-doctor commands work locally without failing so I don't know why the krdpserver would run into this "failed to create wl_display" issue. Logs when restarting app-org.kde.krdpserver: (multiple occurrences of the "Starting KRDP Server..." ... "Failed to start KRDP Server." sequence below. This is the tail end of the log) Oct 16 21:51:57 excalibur systemd[1035]: Starting KRDP Server...
