 |
|
The Kensington Expert Mouse (which is really a trackball) gets top marks on every review, so I figured I'd give it a shot.
Now, I want to use it left-handed. The trackball is set up as follows: there is a big ball in the middle, with a ring around it for scrolling and four buttons (call them SW, SE, NW, NE). I want to map it for left-handed use, as follows:
SE: main click
SW: alternative (normally "right") click
SW+SE: middle click
wheel: as normal
NW: "back" in the browser
NE: "forward" in the browser.
I have the following in xorg-conf.d/11inputs.conf:
| Code: | Section "InputClass"
Identifier "Expert Mouse"
MatchProduct "Kensington Kensington Expert Mouse"
MatchIsPointer "on"
MatchDevicePath "/dev/input/event*"
Driver "evdev"
# Physical button #s: A b D - - - - B C b = A & D simultaneously; - = no button
# Option "ButtonMapping" "1 8 3 4 5 6 7 2 2"
# Option "ButtonMapping" "1 8 3 4 5 6 7 2 2" # For right-hand placement
Option "ButtonMapping" "3 2 1 4 5 6 7 8 9" # For left-hand placement
#
# EmulateWheel refers to emulating a mouse wheel using Marble Mouse trackball.
Option "EmulateWheel" "false"
# Option "EmulateWheelButton" "8" # Factory default; use "9" for left-side placement.
# Option "EmulateWheelButton" "8"
# Option "ZAxisMapping" "4 5"
Option "ZAxisMapping" "4 5"
# Option "XAxisMapping" "6 7" # Disable this for vertical-only scrolling.
# Option "XAxisMapping" "6 7"
# Emulate3Buttons refers to the act of pressing buttons A and D
# simultaneously to emulate a middle-click or wheel click.
Option "Emulate3Buttons" "true"
# Option "Emulate3Buttons" "true" # Factory default.

This does not seem to work. Instead, I get SW and SE working as desired, but using the two together does nothing, NW returns a middle-click, and NE returns "back" in the browser.
I've tried mucking around with the order of numbers, to no avail. Can anybody help me straighten it out?
Cheers,

ADDENDUM2: I've now modified the buttonmap several times with xmodmap. Here's where I am now:
| Code: | $ xmodmap -pp
There are 12 pointer buttons defined.
Physical Button
Button Code
1 3
2 8
3 1
4 4
5 5
6 6
7 7
8 2
9 9
10 10
11 11
12 12
|
If I try to modify any of buttons 9--12 to something other than their default settings, I get this:
| Code: | $ xmodmap -e "pointer = 3 2 1 4 5 6 7 8 9 2 2 2"
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 116 (X_SetPointerMapping)
Value in failed request: 0x2
Serial number of failed request: 9
Current serial number in output stream: 9
