Comment 2 for bug 635457

I have attached a patch that will fix the button problem at: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/582809

The Linux kernel does not currently support the new Synaptics multitouch protocol that the Windows 7 driver uses. Furthermore, the touchpad doesn't seem to reset properly when switching between the multitouch protocol to the old absolute protocol. This happens when the computer is restarted to boot Ubuntu after running Windows. You can avoid this issue by powering off the computer before booting Ubuntu.
