[SOLVED] Can't disable emulation of 3 buttons

[noerrorsfound]

This stupid option that's useless for most people and a hindrance to gamers is still enabled by default, and there's no way to turn it off in System | Preferences | Mouse. In my xorg.conf I have emulate3buttons set to off/false/no but it doesn't disable the "feature". That method worked before version 8.10 of Ubuntu.

Add the following inside the <device> section in /usr/share/hal/fdi/policy/10osvendor/10-x11-input.fdi:

   <match key="info.capabilities" contains="input.mouse"> 
      <merge key="input.x11_driver" type="string">mouse</merge> 
      <match key="/org/freedesktop/Hal/devices/computer:system.kernel.name" 
             string="Linux"> 
        <merge key="input.x11_driver" type="string">evdev</merge> 
      </match> 
 
      <!-- this here is what actually disables the 3 button emulation - the rest above is just the default stuff found in this file --> 
      <merge key="input.x11_options.emulate3buttons" type="string">False</merge> 
    </match>

It will get picked up once the system-wide HAL instance is restarted, easiest is to reboot.

Also, see Ubuntu bug #54191.
