Created attachment 40055 elo-adjustable-screen-size.patch
The intel driver only allows for one X screen in dual-head mode, and elographics normally uses the size of the entire screen to calculate touch event locations.
This patch adds ScreenWidth and ScreenHeight configuration options to override the screen size, and ScreenXOffset and ScreenYOffset in case the touchscreen covers part of the screen that doesn't begin at (0,0).
