I've done a clean install of 12.10 on an HP DV7. According to xinput I do have a PS/2 Synaptics Touchpad. It shows PS/2 Synaptics Touchpad at ID=11 and Virtual core XTEST pointer listed above it at id=4.

I ran ps aux | grep syndaemon and it shows:

jason     5198  0.0  0.0  13580   888 pts/1    S+   09:40   0:00 grep --color=auto syndaemon

I can't get the touchpad menu to show up and the touchpad behaves odd but it could just be me. I should note that this is a clickpad and not just a touchpad.

I ran: egrep -i 'synap|alps|etps' /proc/bus/input/devices

Which resulted in: N: Name="PS/2 Synaptics TouchPad"

I ran: sudo apt-get install xserver-xorg-input-synaptics

But it says I already have the latest/newest version.

when I ran: xinput --list-props 11
