I had trouble getting my Dell XPS M1530 track pad/touch pad to work when I updated the BIOS from A07 to A09. However, it is fairly an easy fix.
Edit your ‘/boot/grub/menu.lst’ file with:
sudo gedit /boot/grub/menu.lst
at the end of the ‘kernel’ line. It may look like below:
title Ubuntu 8.04, kernel 2.6.22-14-generic root (hd0,0) kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=446ea0c-57b1-4112-939c- 3f1d74be9f5f ro quiet splash i8042.nomux=1 initrd /boot/initrd.img-2.6.22-14-generic quiet
Save the menu.lst file and reboot. This should get your track pad/touch pad working.
