Talk:Synaptics TouchPad driver for X
From ThinkWiki
I prefer use the trackpoint instead of the touchpad for pointer movement but find the horizontal/vertical scrolling using the right/bottom edges of the touchpad useful. I have configured my touchpad so that its entire area is scrollable by changing the edge coordinates in my xorg.conf. Now I can can control the pointer with the trackpoint and scroll windows horizontally and vertically at the same time by dragging my thumb around anywhere on the touchpad, like a 2-axis scrollwheel or a scrollball. Unfortunately, these settings seem to get lost when resuming from hibernation (suspend2) but there is no problem when using sleep/suspend to ram.
My xorg.conf Touchpad config section:
Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "SHMConfig" "on"
# Set up a very small touchpad area so that the up/down
# and left/right scrolling areas take up the entire
# touchpad. This makes it possible to use the entire
# touchpad for scrolling and the superior trackpoint
# for cursor movement ;)
Option "UpDownScrolling" "1"
Option "LeftRightScrolling" "1"
Option "LeftEdge" "0"
Option "RightEdge" "1"
Option "TopEdge" "0"
Option "BottomEdge" "1"
Option "TapButton1" "0"
Option "TapButton2" "0"
Option "TapButton3" "0"
# The above non-standard settings for the edges
# causes some odd tapping behavior so turn
# off all corner button options.
Option "RTCornerButton" "0"
Option "RBCornerButton" "0"
Option "LTCornerButton" "0"
Option "RBCornerButton" "0"
EndSection
