Comment 12 for bug 195412

I also have this problem here.

I upgraded from Gutsy to Hardy and my touchpad stopped working completely (it was working perfectly in Gutsy). I have to:
sudo rmmod psmouse && sudo modprobe psmouse

to make it work in the same level described in this bug report (no advanced features and jerky behaviour).

My laptop is a Gateway 5570Z (model 5570-2607), and touchpad is detected as (in /proc/bus/input/devices):

I: Bus=0011 Vendor=0002 Product=0007 Version=12b1
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio4/input0
