General Touchscreen Properties:
Optional properties for Touchscreens:
- touchscreen-min-x : minimum x coordinate reported (0 if not set)
- touchscreen-min-y : minimum y coordinate reported (0 if not set)
- touchscreen-size-x : horizontal resolution of touchscreen
(maximum x coordinate reported + 1)
- touchscreen-size-y : vertical resolution of touchscreen
(maximum y coordinate reported + 1)
- touchscreen-max-pressure : maximum reported pressure (arbitrary range
dependent on the controller)
- touchscreen-fuzz-x : horizontal noise value of the absolute input
device (in pixels)
- touchscreen-fuzz-y : vertical noise value of the absolute input
device (in pixels)
- touchscreen-fuzz-pressure : pressure noise value of the absolute input
device (arbitrary range dependent on the
controller)
- touchscreen-average-samples : Number of data samples which are averaged
for each read (valid values dependent on the
controller)
- touchscreen-inverted-x : X axis is inverted (boolean)
- touchscreen-inverted-y : Y axis is inverted (boolean)
- touchscreen-swapped-x-y : X and Y axis are swapped (boolean)
Swapping is done after inverting the axis
- touchscreen-x-mm : horizontal length in mm of the touchscreen
- touchscreen-y-mm : vertical length in mm of the touchscreen
Deprecated properties for Touchscreens:
- x-size : deprecated name for touchscreen-size-x
- y-size : deprecated name for touchscreen-size-y
- moving-threshold : deprecated name for a combination of
touchscreen-fuzz-x and touchscreen-fuzz-y
- contact-threshold : deprecated name for touchscreen-fuzz-pressure
- x-invert : deprecated name for touchscreen-inverted-x
- y-invert : deprecated name for touchscreen-inverted-y
