The mouse is visible on the black part, and i can drag windows from there. Print screen produces a normal pic with all the desktop as it should look like.
I have this problem with 2 atom n270 laptops, With the first one I could "fix" it temproary by connecting an external screen, then switching to CLI (Ctrl+Alt+F1) and back to the gui (Ctrl+Alt+F7). It might be a temporary fix for the second laptop too, just didn't check it.
It happens only in 17.10 versions (Ubuntu, Ubuntu mate, Lubuntu). Previous versions of Ubuntu are fine. Also Windows and Manjaro are fine.
