When I hit “Reboot” from KDE main menu, when connected remotely via VNC; all it does is to disconnect me, end my session, log me off, but system is NOT rebooted
There is no indication in /var/log/messages or dmesg that system was rebooted.
One has to open Konsole and run CLI command to really reboot the system:
$ sudo systemctl reboot
Then, and only then, there is clear indication that system was rebooted.
Same goes for power off (shutdown).
Am I doing something wrong? Is it expected behavior when one is connected via VNC?
