Public bug reported: Blank Screen initiates after timeout (usually 5 minutes but set to 1 minute to replicate this bug), screen goes blank on both laptop and external Dell, but immediately comes back on. Whilst it is blanking, any running applications show their windows (which is not usual) but it appears gnome-shell and the window manager are not running (no dash and no window decorations).
Disconnecting external monitor exhibits the same Blank Screen failure on the laptop screen. I have turned Automatic Screen Lock off for now to remove that as a cause. I have also had intermittent failure of gnome-shell.
