[Edward-douse <1272624@xxxxxxxxxxxxxxxxxx>]

Scott, if you get chance, also test ElementaryOS. I have just switched
from that to Ubuntu and Ubuntu Gnome 14.04 for testing and my touchpad
(Lenovo Z500) is also quite jerky. Or rather I suppose I would describe
it as a grainy movement. In ElementaryOS it was fine although it is also
jerky in 12.04 which ElementaryOS is based upon.

I'm going to try and find out if the Elementary team adding anything
else to their distro.


Might not help, but if 12.04 is the same..might be worth a shot.
