Initially the lxqt-powermanagement message does not appear. After I press CTRL+ALT+T in Lubuntu 18.10, the entire desktop flickers and the lxqt-powermanagement message appears and the mouse cursor dissapears, when I move the mouse cursor it reappears at the edges of the desktop and dissapears to the center of the desktop. Tested in virtualbox on another computer with settings 512 MB RAM and PAE enabled and works very well there.
