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.
