configuring a scroll wheel for a touchpad

derzok · 02-27-2007, 10:41 AM

I am using a toshiba satellite 2415-S205 with linux slackware 11 (2.6) and I would like to install something that allows me to use mouse gestures with the touchpad. I would like a strip down the right hand side of the mouse pad to be interpreted as a scroll wheel so that when I move my finger up and down that part of the pad, it scrolls whatever window is on the screen.

Does anyone know what the best way to do this is?

If your touchpad supports the Synaptics driver (the one on my Toshiba 5105-s607 does), you can set this in your xorg.conf:

Code:

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0" 1600 0
    Screen      1  "Screen1" RightOf "Screen0"
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Synaptics" "CorePointer"
    InputDevice    "Mouse0" "CorePointer"
EndSection
.
.
.
Section "InputDevice"
        Identifier  "Synaptics"
        Driver      "synaptics"
        Option      "Device" "/dev/input/mice"
        Option      "Protocol" "auto-dev"
        Option      "Emulate3Buttons" "no"
        Option      "ShmConfig" "on"
        Option      "MaxTapTime" "0"
        Option      "TapButton1" "0"
        Option      "TapButton2" "0"
        Option      "TapButton3" "0"
        Option      "HorizScrollDelta" "0"
EndSection

I also disable the tap buttons above to prevent accidentally clicking on something when my palm hovers over the touchpad while typing, and the horizontal scroll which can be annoying. For more information on the function, 'man synaptics'.
