A simple matter of…

Upgraded desktop to Linux 2.6.30 (and newer NVIDIA drivers), this also upgraded me to Xorg 7.4.

As a result, my Logitech G7 mouse changed behaviour. Instead of the horrible side “back” button doing middle click as I like, it started doing back. Pressing a scroll wheel as often as a Unix user does is not nice nor accurate.

After about an hour of fighting xorg.conf I eventually got “xinput” to work using:

 xinput set-button-map 4    1 8 3 4 5 6 7 2

NB: “xinput set-button-map 4 1 8 3 4 5 6 7″ doesn’t work. However I could not get “ButtonMapping” in xorg.conf to work, even in an evdev section like this:

Section "InputDevice"
       Identifier      "evdev mouse"
       Driver          "evdev"
       #Option         "Name"  "Logitech USB Receiver"
       Option          "ButtonMapping"         "1 8 3 4 5 6 7 2"
       Option          "SendCoreEvents"
EndSection

Finally I succeed by edit hal - /etc/hal/fdi/policy/preferences.fdi to be precise need this bit including:

<device>
  <match key="info.capabilities" contains="input.mouse">
   <merge key="input.x11_driver" type="string">evdev</merge>
   <merge key="input.x11_options.ZAxisMapping" type="string">4 5 6 7</merge>
   <merge key="input.x11_options.ButtonMapping" type="string">1 8 3 4 5 6 7 2</merge>
  </match>
</device>

Discovering that even though I’ve set “DontZap” to false it is ignored (since the default has changed to true) didn’t improve my mood.
