Tried and confirmed it on a second laptop (Manjaro, too): 1) As scaling 1.0 is used, there's no scaling issue after plugging the cable out 2) The desktop freezes for ~ 10 seconds and finally I find myself logged out too. Like on the other system, I cleared the cache ~/.cache/* and rebooted before my tests. How can I further debug this issue for you? Which outputs / information do you need? possibly duplicate of bug 419728 (In reply to Patrick Silva from comment #2) > possibly duplicate of bug 419728 Can you please quickly tell me how I can get the debug log / crash log if there's one? I'd like to test it ASAP. Very likely a duplicate. Will look for a crash log later. *** This bug has been marked as a duplicate of bug 419728 *** I use gdbserver, ssh and gdb to remotely get backtrace of kwin_wayland crashes. |
Created attachment 131344 [details] (External monitor plugged in) qdbus org.kde.KWin /KWin supportInformation SUMMARY Plasma automatically logs me out when the external HDMI connected TV (as the only screen), becomes unplugged. This happens only on Wayland for me. On X11 it changes the screen back to the laptop, but with scaling issues. STEPS TO REPRODUCE 1. Plugin in an external FullHD TV via HDMI 2. If Plasma doesn't automatically changes display configuration to "External Monitor only", make sure to display content only on the external device (haven't tested other cases yet) 3. Finally unplug the cable OBSERVED RESULT The screen goes back to the laptop for two seconds -- but with a wrong scaling (at least the panel is too big). It's not possible to interact with anything. Finally I become log out. EXPECTED RESULT Screen moves back to the laptop without any scaling issues or whatever.
