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"

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:


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. –  Marco Ceppi Jul 20 '11 at 12:58
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. –  lhw Jul 26 '11 at 9:33
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. –  user27002 Oct 14 '11 at 3:37

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.

so, no udev-hacking is needed anymore? –  pschmidt Aug 3 '11 at 22:55

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/… –  lhw Jun 18 '12 at 21:44
