After resuming a logged-in Plasma session, the screen is blank. On logging in remotely, I see:
$ systemctl status sddm ● sddm.service - Simple Desktop Display Manager Loaded: loaded (/usr/lib/systemd/system/sddm.service; enabled; preset: enabled) Drop-In: /usr/lib/systemd/system/service.d └─10-timeout-abort.conf Active: active (running) since Tue 2023-10-10 08:01:41 BST; 1h 28min ago Docs: man:sddm(1) man:sddm.conf(5) Main PID: 1149 (sddm) Tasks: 2 (limit: 19015) Memory: 21.1M CPU: 52ms CGroup: /system.slice/sddm.service └─1149 /usr/bin/sddm

(The system was resumed at 08:00am)
$ systemctl status plasma 921 earlyoom $ systemctl status kwin 921 earlyoom
When I switch to gdm and reboot, then hibernate and resume manually, everything works as expected.
Is this a known bug?
