If the uinput device has an absolute pointer (as opposed
to a normal mouse that is a relative pointer) you can
specify the option "abs". Note that a touchpad
on a laptop is an absolute device t some degree.
This (usually) avoids all the problems with mouse
acceleration. If x11vnc has trouble deducing the size
of the device, use "abs=WxH". Furthermore, if the
device is a touchscreen (assumed to have an absolute
pointer) use "touch" or "touch=WxH".
