touchpad doesn't work after upgrade to xserver-xorg-lts-quantal

Yesterday I upgraded to xserver-xorg-lts-quantal. After a reboot, the Synaptics touchpad doesn't work anymore. My Logitech trackball (connected as a Logitech Unifying Device) still works).

Hmmm... xserver-xorg-input-all-lts-quantal and xserver-xorg-video-all-lts-quantal got dropped when upgrading. Installing the latter fixed the touchpad.
