auto selected trackpad features gone

[chris...]

Recently my trackpad features stopped working

I am using evdev as the input driver
I have no settings in xorg, hal, udev for the mouse
Everything worked fine letter it auto setup everything

The features that have gone are:
Right side scrolling
No simulated middle mouse button
No auto copying when highlighting
Trackpad is now too sensitive

My xorg file is blank and far as I know their are no config files I can post
It used to work fine until recently on both my current laptop and my old laptop

I've added the following to xorg.conf
The scrolling still doesnt work and the trackpad is still a bit sensitive
