I have the same problem, I've upgraded from Feisty to Gutsy though. The vertical scroll doesn't work neither.
I tried this InputDevice, that is what I used in Feisty without problems: Section "InputDevice" Identifier "Synaptics Touchpad" Driver "synaptics" Option "SendCoreEvents" "true" Option "Device" "/dev/psaux" Option "Protocol" "auto-dev" Option "HorizScrollDelta" "0" Option "SHMConfig" "on" Option "TapButton1" "0" EndSection and this one, that is the one automatically generated: Identifier "Synaptics Touchpad" Section "InputDevice" Identifier "Synaptics Touchpad" Driver "synaptics" Option "SendCoreEvents" "true" Option "Device" "/dev/psaux" Option "Protocol" "auto-dev" Option "HorizScrollDelta" "0" EndSection My driver is xserver-xorg-input-synaptics Version: 0.14.6-0ubuntu10 It is very annoying and render the touchpad useless.
