I have a tablet with touchscreen. Everything works OK on the desktop for landscape and portrait ( screen rotation and touch rotation ).
But on the login screen ( greeter )the screen rotation is OK but the touch rotation doesn't work properly. When I keep my tablet in portrait and if I just rotate to landscape - screen rotate as it should but the touch rotation is still in portrait mode...
How to fix touch screen rotation - now looks like stuck in portrait mode and don't want to rotate with the screen - that happens only on the login screen ( greeter ).
