Hi,
I've got a Acer TravelMate 8471 running Ubuntu 10.10 x64 (upgraded from 10.04, but this is a week ago, and should not have anything to do with my problem).
Under mouse-preferences > Touchpad, the two-finger scroll option is grayed out, but by setting the value manually in gconf, it have been working just fine until today (I've tried to figure out what made it screw up, but I can't find anything that would have any influence).
When I try to enable two-finger scrolling, the driver never figures out that I've got two fingers on the pad, and instead my mouse flies around on the screen.
I've tried configuring the driver through xinput with a script I've used before:
Code:
xinput --set-prop --type=int --format=32 "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Pressure" 10
# 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" 7
# 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 1
# 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" 120
But even this fails.
When I tried using synclient with these four commands:
Code:
synclient HorizTwoFingerScroll=1
synclient VertTwoFingerScroll=1
synclient EmulateTwoFingerMinW=5
synclient EmulateTwoFingerMinZ=48
it begins scrolling, but it scrolls rapidly up and down while and for some time after I've tried to use two fingers.
Any help is appreciated.
