Multi-button mouse on X11: How can I configure several buttons to act as the middle button?
Solution 1
I think you can configure the Option "ButtonMapping"
in your mouse's Section "InputDevice"
of xorg.conf
. There you should set the physical button(s) to logical button 2
.
E.g.:
Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "auto"
Option "Device" "/dev/psaux"
Option "Emulate3Buttons" "no"
Option "ZAxisMapping" "4 5"
Option "ButtonMapping" "1 2 3 4 5 2"
EndSection
Solution 2
To make the left and right buttons act as the middle button when pressed together, you need to activate 3-button emulation. In older Xorg releases, set Option "Emulate3Buttons" "yes"
in the appropriate InputDevice
section of xorg.conf.
In Xorg 1.4 through 1.7, add a HAL configuration fdi file such as:
<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
<device>
<!--
Default X.org input configuration is defined in:
/etc/hal/fdi/policy/30user/10-x11-input.fdi
Settings here modify or override the default configuration.
See comment in the file above for more information.
To see the currently active hal X.org input configuration
run lshal or hal-device(1m) and search for "input.x11*" keys.
Hal and X must be restarted for changes here to take any effect
-->
<match key="info.capabilities" contains="input.mouse">
<merge key="input.x11_options.Emulate3Buttons" type="string">on</merge>
</match>
</device>
</deviceinfo>
In Xorg 1.8 and later, add a file in the xorg.conf.d directory such as:
Section "InputClass"
Identifier "middle button emulation class"
MatchIsPointer "on"
Option "Emulate3Buttons" "on"
EndSection

I know how to make another button act as the middle button but how can I map several mouse buttons to the middle button?
xmodmap
complains if I repeat button numbers in thepointer
option. -
