Synaptics touchpad disabled after update in Kubuntu

view full story

http://askubuntu.com – I have one Kubuntu computer running 11.10, after the updates a few days ago my synaptics touchpad died, it simply refuses to run, I am sure its a software thing because it works if I use a LiveCD. Keyboard is working perfect, I can login, open a terminal and use my computer but would be nice to make the touchpad run again. Anyone can guide me on where to find information and how to enable my touchpad again? (HowTos)
