The goal of all this is to get an x/y motion reflecting the motion on the device, i.e. a circle on the device is a circle on the screen. This is currently done by scaling the y coordinate depending on the screen ratio vs device ratio. Depending on that ratio the movement on the y axis may be accelerated (ratio < 1) or slowed (ratio > 1). This leads to the weird effect that changing the screen ratio by plugging a new monitor changes the speed of the touchpad. Use a different algorithm: calculate the physical movement on the device, map that to the same-ish distance on the screen, then convert that back into a device-specific vector. This way we get the same mapping regardless of the current screen dimensions. Since the pointer accel code doesn't take device resolution into account, make sure we apply our crazy mapping before we accelerate. This way we accelerate resolution-independent.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
