Using Plasma/SDDM on X11, after a recent upgrade, when I ask the system to shut down, the system halts, but it does not power off: the lights remain on and the fans continue to spin, even though the system/software is off.
If I run the command (systemclt poweroff) from the command line, it works (i.e., it does power off). Is anyone else experiencing the same? Any ideas or suggestions?
Some info about the system:
