When I start out running 11.10 (Ocelot) from the Live CD the touchpad works with no problem. Once installing however the touchpad does not work at all. I have installed all updates available.

I have tried installing the synaptiks touchpad package and the gpointer package from the software manager, this did not help.

Under System Settings -> Mouse and Touchpad there is only a mouse tab, no touchpad tab. It seems my touchpad is not even recognized.

I have tried running several things in the terminal that I have found under similar questions, but I always get errors about the files not being found, or the drivers not being found.

Have tried:

sudo modprobe -r psmouse
sudo modprobe psmouse proto=imps

This results in an error message.

Can load the GUI, but after that I can't seem to navigate through it to find the files that need editing.

Read what's listed here.

But I've got no GRUB, running only Ubuntu.

As you can see I've been trying several things and nothing has worked so far, would appreciate any help.

Known problem. Just install all updates and reboot. –  RobinJ Feb 24 '12 at 17:44

The link is dead for the driver, found another one here: psmouse-alps-dkms_0.10_all.deb, for anybody who has the problem.
For your information, I had the problem on the Lenovo Y580.

I found this and worked for me - at this site http://ubuntuforums.org/showthread.php?p=11478976

I downloaded and installed the driver indicated from here: http://people.canonical.com/~sforshee/alps-touchpad/psmouse-alps-0.10/psmouse-alps-dkms_0.10_all.deb

After installation and restart it works the way it is supposed to.
