I’m using a clean install of Ubuntu 16.04, on an LG laptop which is quite old, which happens to get “stucked” in full screen mode when running programs ( for example -VNC Viewer, imageViewer ).

PC is not FROZEN since mouse moves OK but I can’t get out from full screen mode- which ends with hard shutdown.

  1. Any known reasons for that ?

  2. Is there any key combination as CTRL+ALT+DEL in Ms-Windows for such situations ?

I encounter the same issue. I entered ctrl+alt+f2 which took me to the logger page and then i hit ctrl+alt+del and all of a sudden my laptop restarted.
