Issue:
Using a fresh install of Ubuntu 14.10, I discovered that the touchpad did not work.

Steps to reproduce:
Install Ubuntu 14.10 on a Fujitsu H730 and attempt to use the touchpad.

Further description:
However, I stumbled across bug #1300427, where there was mention of both a workaround and a fix in a newer kernel.
I have been able to use the workaround -- which is basically limiting the protocol of the psmouse module, such that I remove and load psmouse with proto=exps.

After this, a bit further in time, I accidentally managed to click with the touchpad. It appears that the touchpad strangely enough works quite well as long as I hold down the middle click button. While holding it down, the touchpad seems to work rather well - including multitouch features.
The joy is short, as it registeres no input while depressed.
