Ok it is using the psmouse module. Try:

sudo modprobe -r psmouse && sudo modprobe psmouse

Does that make it work?

No I'm afraid not. Would I need to reboot?

Try running:

gksudo gedit /etc/default/grub

Change:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to:
GRUB_CMDLINE_LINUX_DEFAULT="i8042.nomux quiet splash"

Save the new file, close gedit and run:

sudo update-grub

Reboot to test.

Still no joy.

ok remove the boot option and rerun sudo update-grub.

Do you have a shortcut to disable and enable the touchpad?

There's a button for disabling it. It's definitely set to enable, though I've tried it both ways. Don't know about a keyboard shortcut, I don't think sol

I can't see anything that looks like a boot option for it.

Are there any bugs reported?

Nothing has popped up, but I don't know where exactly to look?

That worked. Thank you very much for your help.

Does it survive reboot?

No, it doesn't survive reboot. If there's a way to make it do so that'll be great. Otherwise I'm satisfied to have a way of enabling it.

Thanks actionparsnip, that solved my question.

add a startup item to run:

gconftool-2 --set /desktop/gnome/peripherals/touchpad/touchpad_enabled --type=bool true

It will do it automagically at logon

Thank you, that's perfect.
