Comment 576 for bug 550625

ndkhoi168: There's no way for us to know that you have the particular kind of touchpad that this driver supports. Supposing it is, you need to use the synclient program to review and set the options. Simply installing the d river does not necessarily do any good. You need to be sure the kernel module is loading and then configure everything.

I don't see any attachments with your post, but I'm not sure they would help me anyway. I want to see the output of

$ synclient -l

I see this output.
~$ synclient -l

 If, after a system restart, you can do this to see if the psmouse module is running.

$ /sbin/lsmod

will list all modules loaded. make sure psmouse is in there.

If not, run

$ /sbin/modprobe psmouse

When I force the mouse driver to be removed and restarted, I see this in dmesg output:

Only after you make sure there will y ou have any hope of configuring the thing with synclient.

If you get psmouse loaded, and synclient shows output, then I'd say you probably need to ask for help from Ubuntu users, since not all versions of linux will have exactly the same problems.
