Here's touch calculations taken from Android documentation on Linux touch
input:
xScale = output.width / raw.width
yScale = output.height / raw.height
If not orientation aware or screen rotation is 0 degrees:
output.x = (raw.x - raw.x.min) * xScale
output.y = (raw.y - raw.y.min) * yScale
Else If
For input, I am using xf86-input-evdev . I am not using the proprietary
eGalax driver. I might be wrong about the input rotating with the screen.
The problem is the mouse cursor/pointer location does not correspond to the
touch input. The movement of the cursor does correspond to the touch input,

Ok, I was wrong. Looked at Xorg logs, and it shows that the
/dev/input/mouse* devices that correspond to the touchscreen are not picked
up by any of the existing configurations in xorg.conf.d

I think I figured out what's wrong.
udev creates two input devices for the touchscreen:
- Touch input
- Mouse input
I guess this is done to emulate the touchscreen as a mouse so that it can
be used with existing GUI's without requiring applications to handle touch
input.
Mouse input is configure
