To remove the module, log in, open a terminal and run the following commands. Reboot the system and you should be back to square one... a working mouse but left click only.
Let me know how you get on with that.
1. sudo dkms uninstall -m psmouse -v 3.2.0-24-generic-pae
2. sudo dkms remove -m psmouse -v 3.2.0-24-generic-pae --all
