ALPS Touchpad in UBUNTU 11.04

[Pritam Baral]

There's a workaround to that. First try out these commands in order:

$ sudo modprobe -r psmouse
$ sudo modprobe psmouse proto=imps

Check if touchpad AND scrolling work now. If they do, add the following line
to /etc/modprobe.d/psmouse.conf (create the file if it doesn't exist):
options psmouse proto=imps

Shortcut to the above operation:
$ echo "options psmouse proto=imps" | sudo tee -a
/etc/modprobe.d/psmouse.conf
