same issue here with the 1420n, my xorg.conf sysnaptics input devices section
Section "InputDevice" Identifier "Synaptics Touchpad" Driver "synaptics" Option "SendCoreEvents" "true" Option "Device" "/dev/psaux" Option "Protocol" "auto-dev" Option "HorizScrollDelta" "50" Option "SHMConfig" "on" EndSection
Going to VT and the back to X it works again. This is an really annoying issue.
