I opened a new X session at :1  I run a game that renders its own mouse pointer (that has low FPS), so the X cursor is hidden.I need to force the X cursor to show above the application self rendered cursor.That way I know where the mouse precisely is so I can wait there for the application mouse pointer to be rendered (even if it renders with a displacement).OBS.: I am using JWM, so there is no Gnome, Compiz/Unity or KDE at :1Failed Attempts: DISPLAY=:1 xsetroot -cursor_name left_ptr #trying to unhide the mouse pointer or to change its graphics so it show up again  xinput set-prop A4Tech USB Mouse Device Enabled 1 #but the mouse is already enabled there so did not work... (from this tip)
