Need to press Super key after "." or "b" to blackout screen in presentation mode
Submitted by vladox
Blackout screen used to work with a previous version (the one that came with ubuntu 16) out of the box, via pressing "." or the black screen button on remote control. Now it seemingly doesn't, unless you press Super (Windows) key to get the Gnome Dash. When you return to presentation, screen will now be blacked out. It is just a minor annoyance, which I would really appreciate you could fix. Thanks!
