That's interesting... I have a Kensington 7-button mouse (including
scroll wheel) http://ftp.kensington.com/pdfs/OpticalFS.pdf
I wanted to use one of the extra buttons as the gesture button. Here
are the two (sensible) combinations that I tried:
(running XFree86 4.1, kernel 2.4.19-rc3-ac3).
This is what I thought it should be:
Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ImPS/2"
Option "Buttons" "7"
Option "ZAxisMapping" "4 5"
EndSection
(What should protocol be for /dev/input/mice?)
Result: Everything works except for buttons 6 and 7. The scroll wheel
reports as buttons 4 and 5, and scrolling works fine. When I hit the
first extra button, however, it reports as button 2, and the second extra
button reports as button 3 (as verified by xev).
So I tried this:
Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ImPS/2"
Option "Buttons" "7"
Option "ZAxisMapping" "6 7"
EndSection
Result: The scroll wheel reports as buttons 6 and 7. Therefore, scrolling
doesn't work. The extra buttons on the mouse still report as buttons 2 and 3.
So I gave up. :) I figured it was an X limitation. Maybe not...?
