Hmm, downgraded xfce-power-manager to the previously installed version, didn't help. Same exercise for gnome-settings-manager (which updated at the same time), did not help. Well, because downgrading did not help, I upgraded both of them to the current version again. Result: everything works fine. No clue what was going on there.
