The synaptics touchpad can be used as a scroll wheel mouse. This is well documented in the man page, but I thought I'd post the relevant section from my xorg.conf just incase anyone is having trouble configuring theirs. I've used the same section on a T41,T43p and T60p. Section "InputDevice" Identifier "Synaptics" Driver "synaptics" Option "Device" "/dev/input/mice" Option "Protocol" "auto-dev" Option "Emulate3Buttons" "yes" Option "LeftEdge" "1700" Option "RightEdge" "5300" Option "TopEdge" "1700" Option "BottomEdge" "4200" Option "FingerLow" "25" Option "FingerHigh" "30" Option "MaxTapTime" "180" Option "VertScrollDelta" "100" Option "HorizScrollDelta" "1200" Option "MinSpeed" "0.06" Option "MaxSpeed" "0.12" Option "AccelFactor" "0.0010" Option "SHMConfig" "on" EndSection
