Found the problem!

Somewhere is the bespoke input logic for Unity8 we're assuming the
device is (typically) around 100Hz so also generates large motion
deltas. That's incorrect. My mouse is configured for 1000Hz so generates
small (but many) deltas. You can test this with a sufficiently capable
mouse using kernel parameter: usbhid.mousepoll=1.

Removing that kernel parameter fixes the speed. Although we should fix
Unity8 because Xorg and Mir's demo servers don't have such problems with
1000Hz mice.

Title:
  Mouse cursor moves way too slow in Unity 8

Bug description:
  Logging in to Unity8 on desktop (xenial) the mouse cursor moves
  glacially slow. I have to move the mouse across the whole desk to get
  anywhere. This is surprising given bug 1524145 shows the opposite is
  happening in the Mir demo servers.
