width:—> 480
height:—> 320
framebuffer:—> /dev/fb1

6/ Restart
7/ Screen displays correctly.
8/ Touch screen XY reversed i.e. vertical movelments produce horizontal movement of cursor
9/ Attempting to select items on screen in admin virtually impossible with reversed axis, and mouse operation continually drops back to selecting top menu item, similar behaviour with keyboard ( re-position not triggered by anything specific it just moves back)
10/ Any attempt to select a different menu item selects the top item in select list…
11/ Hurl device at wall using technique described by @riban and chuckle lightly at being the person who gave him the screen.
