Getting the touchpad to work in Ubuntu 8.10 Intrepid Ibex

Open a terminal and type this:

gksudo gedit /boot/grub/menu.lst

This should ask you for your password and open the GRUB configuration file.
Now you add i8042.nomux=1 at the end of theese lines:

kopt=root=blablabla ro i8042.nomux=1
...
defoptions=quiet splash i8042.nomux=1
...
title  Ubuntu 8.04.1, kernel 2.6.24-19-generic
root  (hd0,6)
kernel  /boot/vmlinuz-2.6.24-19-generic root=UUID=8b094197-a280-44ce-9f1f-0355ae2541ef ro quiet splash i8042.nomux=1
initrd  /boot/initrd.img-2.6.24-19-generic
quiet

NOTE: You need to add this to the line(s) of the kernel(s) you are currently using AND you have to add if after EVERY kernel upgrade.
