After upgrading Ubuntu 8.04 to 8.10 I had a problem with slow touch pad. After some research I found solution in Ubuntu documentation.

Here is what I’ve done to enable touch pad configuration and solve the problem of gsynaptic asking to enable SHMConfig in xorg.conf:

Alt+F2

user@computer:$ gksudo gedit /etc/hal/fdi/policy/shmconfig.fdi

Paste this code:

<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
    <device>
        <match key="input.x11_driver" string="synaptics">
            <merge key="input.x11_options.SHMConfig" type="string">True</merge>
        </match>
    </device>
</deviceinfo>

Save and close that file, reboot, and SHMConfig should be enabled. You can set up your touch pad by going to System -> Preferences – Touchpad
