Bug Description
I made a fresh install of Precise on a Lenovo X200 a couple weeks ago. When I start a new session after booting, the mouse is very slow and it feels like something might be taking up lots of resources on the system. After a few minutes, the problem goes away and the mouse works perfectly.

Creating a basic xorg.conf file and adding these lines works around the problem:

Identifier "HDMI1"
Option "Ignore" "True"
