63Currently the kernel is not able to automatically determine from which ACPI

285-----------------------
286Some laptops, most notably the Lenovo *40 series provide a trackstick
287device but do not have physical buttons associated with the trackstick
288device. Instead, the top area of the touchpad is marked to show
289visual/haptic areas for left, middle, right buttons intended to be used
290with the trackstick.

292If INPUT_PROP_TOPBUTTONPAD is set, userspace should emulate buttons
293accordingly. This property does not affect kernel behavior.
294The kernel does not provide button emulation for such devices but treats
295them as any other INPUT_PROP_BUTTONPAD device.
