This answer to this question fixed my mouse cursor which had disappeared and was not responding to inputs. The answer suggested going into text mode (using Ctrl+Alt+F1 ) and immediately back to graphical mode (using Ctrl+Alt+F7) and it worked perfectly well. Why does this happen though, does the interface get restarted or something similar when we do this?

          Sometimes, the display of the mouse cursor is implemented as a hardware overlay a.k.a. "sprite". There is an X.org option called HWCursor (hardware cursor).



          So resetting all the graphics modes may fix an error in the hardware cursor configuration.
