[Bug 48134] [NEW] scroll wheel events not available to X under synaptics driver

 

You have been subscribed to a public bug:

Binary package hint: xorg-driver-synaptics

under breezy and dapper, but not some other older configurations
(mandriva), my laptop's hardware scroll-wheel (also the middle button,
button 2) is not accessible as X events.

I have an ALPS touchpad on a Toshiba Satellite 2410.

Using the Synaptic driver, I get nice features on the touchpad, including a software-run scrolling on the right side of the touchpad,
but the scroll-wheel (a hardware wheel that also works as mouse button 2) does nothing.

When I run xev, it notices button 2 being pressed but gives no notice of
it being scrolled (in particular, there is no mapping of the up and down
rotation of the scroll wheel to buttons 4 and 5).

I have the default entry in xorg.conf:

Section "InputDevice"
        Identifier      "Synaptics Touchpad"
        Driver          "synaptics"
        Option          "SendCoreEvents"        "true"
        Option          "Device"                "/dev/psaux"
        Option          "Protocol"              "auto-dev"
        Option          "HorizScrollDelta"      "0"
EndSection


These buttons should be available to X somehow.
Ideally, the xorg.conf line
        Option          "ZAxisMapping"          "4 5"
should then be useful.
