Up until version 11.04 of ubuntu I could simply add an option to my X InputClass to emulate a third mouse button for my HP TrackPoint like this:

Section "InputClass"
    Identifier "Trackpoint"
    MatchIsPointer "on"
    Option "Emulate3Buttons" "True"
EndSection

I recently updated to the 11.10 to test the new features and I am satisfied so far but the before mentioned method stopped working. I suppose it's related to the x-server update. I also tried adding a udev rule like this:

ENV{x11_options.Emulate3Buttons}="True"

which is also ignored.

Is there anything I missed or something important that has changed?

    11.10 Is an Alpha release. You need to report this as a bug if it's not work as expected.

    I wasn't sure this is a bug. It might just have been another change in the system architecture. Well then. I'm going to report this and see what happens.

  • Doesn't appear to be fixed to me -- it is ignoring my Emulate3Button setting in /usr/share/X11/xorg.conf.d/50-marblemouse.conf that was working fine under 11.04.

The bug seems to be fixed now. Without me reporting it.

In 12.04 and 12.10 the settings can be found with dconf-editor or dconf in /org/gnome/settings-daemon/peripherals/mouse/middle-button-enabled and persist over standby and reboot.

Middle mouse button emulation can be enabled in Ubuntu 11.10 via a little program called gpointing-device-settings:

sudo aptitude install gpointing-device-settings

(see https://grepmonster.wordpress.com/2011/05/31/ubuntu-11-10-middle-mouse-button-emulation/)

    The problem with this is that the setting is only remembered until a suspend or a reboot occurs. The bug report I created for this is ignored like everything else concerning gpointing-device-settings bugzilla.gnome.org/…

The third mouse button can be enabled system wide by adding a file /etc/X11/xorg.conf.d/20-3rdbutton.conf with the following content:

Section "InputClass"
   Identifier "middle button"
   MatchIsPointer "on"
   MatchDriver "libinput"
   Option "MiddleEmulation" "on"
EndSection

I use this on my HP nc2400 with Fedora 23, and it works.

The source of this information is the corrected and adapted config of comment 14 of Red Hat’s bug 1227992.
