I was missing edge scrolling on my Fujitsu XI3650 laptop running Bodhi Linux 2.2.0.
I came across this thread http://ubuntuforums.org/showthread.php?t=1190259, and here is how I ended getting it working:
cd /usr/share/X11/xorg.conf.d sudo nano 50-synaptics.conf
Add the following options to the “InputClass” section with identifier “touchpad catchall”:
Option "SHMConfig" "True" Option "LeftEdge" "0" Option "RightEdge" "850" Option "TopEdge" "300" Option "BottomEdge" "650" Option "EmulateTwoFingerMinZ" "100" Option "EmulateTwoFingerMinW" "0" Option "VertScrollDelta" "7" Option "HorizScrollDelta" "7" Option "HorizEdgeScroll" "True" Option "VertTwoFingerScroll" "1" Option "MaxSpeed" "1" Option "RTCornerButton" "2" Option "RBCornerButton" "3" Option "TapButton2" "0" Option "TapButton3" "0"
