Config section, in xorg.conf, I'm using with the touchpad on a Dell Latitude D620 and Fedora 8, with commented out options I decided not to use:
Section "InputDevice" Identifier "Synaptics" Driver "synaptics" Option "Device" "/dev/input/mouse2" Option "SendCoreEvents" "true" Option "Protocol" "auto-dev" Option "Emulate3Buttons" "yes" #Option "LeftEdge" "120" #Option "RightEdge" "830" #Option "TopEdge" "120" #Option "BottomEdge" "650" Option "BottomEdge" "5000" #Option "FingerLow" "14" #Option "FingerHigh" "15" #Option "MaxTapTime" "180" #Option "MaxTapMove" "110" #Option "ClickTime" "0" #Option "MaxDoubleTapTime" "100" #Option "EmulateMidButtonTime" "75" #Option "VertScrollDelta" "20" #Option "HorizScrollDelta" "20" Option "MinSpeed" "0.3" Option "MaxSpeed" "0.75" #Option "EdgeMotionMinSpeed" "200" #Option "EdgeMotionMaxSpeed" "200" #Option "UpDownScrolling" "1" #Option "CircularScrolling" "1" #Option "CircScrollDelta" "0.1" #Option "CircScrollTrigger" "2" Option "AccelFactor" "0.2" # For KSynaptics Option "SHMConfig" "on" EndSection
I'm intentionally not using the edge scrolling ability. I really prefer something like the middle button/rocker that Acer has on its Aspire series. The stick still works, but I don't use it.
KSynaptics still doesn't act quite right, though. For example I can't enable tapping and must use the buttons. I did need to pick "ALPS touch pad", under "Touch Pad Borders", but I've think I found it best not to use the "Adjust touch pad borders" button.
