What happens on 'Lock' via In-Session toolbar
to help on a TV survey i played with the In-Session toolbar.
I use on both sides linux (openSuse Leap 15.1, KDE, X11)
on 'Action' - 'Lock' - 'Lock Now' the screen in the TV window went black.
And it stays black :-(
started new session: screen is black
restarted the local TV client: connect: screen is black
How to get the login screen again ?
BTW: the 'File Transfer' feature still works.
What happens technically, when I use 'Lock now' ?
