SUMMARY plasmashell fails to start on a laptop with lid closed and an external monitor attached. STEPS TO REPRODUCE 1. Attach a DP monitor to a laptop, close the lid. 2. Reboot. 3. Login with SDDM. OBSERVED RESULT Session starts properly, applications are restored, but background is black and the panel doesn't appear. I can then start plasmashell with krunner. $ ps -C plasmashell PID TTY TIME CMD $ journalctl -b --user /usr/bin/plasmashell lip 24 10:52:18 beton plasmashell[3503]: ASSERT failure in void ScreenPool::screenInvariants(): "ScreenPool ( 0x566d39462ff0 ) Internal state: Screen Order: QList(QScreen(0x566d3914d400, name="DP-1")) "Fake" screens: QSet() Redundant screens covered by other ones: QHash() All screens, ordered by size: QList(QScreen(0x566d3914d400, name="DP-1")) All screen that QGuiApplication knows: QList(QScreen(0x566d3914d390, name="eDP-1"), QScreen(0x566d3914d400, name="DP-1")) ", file ./shell/screenpool.cpp, line 375 lip 24 10:52:19 beton plasmashell[3504]: ASSERT failure in void ScreenPool::screenInvariants(): "ScreenPool ( 0x5c898601bb30 ) Internal state: Screen Order: QList(QScreen(0x5c8985d23400, name="DP-1")) "Fake" screens: QSet() Redundant screens covered by other ones: QHash() All screens, ordered by size: QList(QScreen(0x5c8985d23400, name="DP-1")) All screen that QGuiApplication knows: QList(QScreen(0x5c8985d23390, name="eDP-1"), QScreen(0x5c8985d23400, name="DP-1")) ", file ./shell/screenpool.cpp, line 375 EXPECTED RESULT plasmashell starts.

Do you have a backtrace?
A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/4553
Created attachment 171972 [details] backtrace
As other people can't reproduce it, do you have any chance to test https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/4553 ?
Is there a magic kdesrc-build command to rebuild plasmashell from this MR only? I've got all sorts of dependency errors trying to rebuild plasma-workspace, but maybe there's a simpler way for this package only.

I think you can just clone plasma-workspace and run cmake commands in the folder without kdesrc-build
