On my 2010 samsung N230 laptop, the "two finger scrolling" option
is greyed out. Enabling two finger scrolling works with this
script I found on internet forums.
the touchpad is a synps/2
xinput --set-prop --type=int --format=32 "SynPS/2 Synaptics TouchPad"
"Synaptics Two-Finger Pressure" 4
# Below width 1 finger touch, above width simulate 2 finger touch. -
value=pad-pixels
xinput --set-prop --type=int --format=32 "SynPS/2 Synaptics TouchPad"
"Synaptics Two-Finger Width" 8
# vertical scrolling, horizontal scrolling - values: 0=disable 1=enable
xinput --set-prop --type=int --format=8 "SynPS/2 Synaptics TouchPad"
"Synaptics Two-Finger Scrolling" 1 0
# vertical, horizontal, corner - values: 0=disable 1=enable
xinput --set-prop --type=int --format=8 "SynPS/2 Synaptics TouchPad"
"Synaptics Edge Scrolling" 0 0 0
# stabilize 2 finger actions - value=pad-pixels
xinput --set-prop --type=int --format=32 "SynPS/2 Synaptics TouchPad"
"Synaptics Jumpy Cursor Threshold" 250
# pad corners rt rb lt lb tap fingers 1 2 3 (can't simulate more then 2 tap
fingers AFAIK) - values: 0=disable 1=left 2=middle 3=right etc. (in FF 8=back
9=forward)
xinput --set-prop --type=int --format=8 "SynPS/2 Synaptics TouchPad"
"Synaptics Tap Action" 0 0 0 0 0 0 0
#xinput --set-button-map "SynPS/2 Synaptics TouchPad" 2 1 3 4 5 6 7 8 9
I don't know how to integrate this script into the system, since hal fdi files
seem to be deprecated,
and a simple session start script is insufficient, since the settings are lost
after suspend-to-disk.
So I'm looking for a more long-term solution.
