Comment 12 for bug 1330198

When I get home tonight I'll try the SRU in a new 14.04 install or live session

If you don't see the re-enabling from 'touchpad -disabled' on reboot then there may be some hardware diffs that can affect usb mice, ect.
The greeter always has touchpad -enabled but on this laptop & my prior lenovo (y580p), the user setting of touchpad -disabled is/was always reset to -enabled on reboot/login
(- well, sorta, - that bug migrated from reset at some point during the course of a day or 2 to the current always reset on fresh boot/login
