Please attach an evemu-recording of the event sequence so we can reproduce this here. Middle button emulation should be enabled by default for all touchpads.

Comment 3 Peter Hutterer 2015-04-07 07:18:44 UTC 
whoops, that's actually missing upstream. We implemented it for software buttons, but not for touchpads with physical hardware.

I'll get this into the next libinput version, sorry about that.

Hey guys,

I've have a similar issue with my touchpad device.
My system is a Dell E5430 running F22 x86_64 (with all updates installed).

Someone on the Fedora users list (see the thread: https://lists.fedoraproject.org/pipermail/users/2015-June/461668.html) suggested me to add the following file '/etc/X11/xorg.conf.d/10-evdev.conf':

Section "InputClass"
      Identifier "middle button emulation class"
      MatchIsPointer "on"
      Option "Emulate3Buttons" "on"
      Driver "evdev"
EndSection

But it didn't work.

I've attach the evemu recording.

The last xorg-* updates:

  xorg-x11-drv-libinput-0.10.0-5
  xorg-x11-server-common-1.17.1-14
  xorg-x11-server-Xorg-1.17.1-14
  xorg-x11-server-Xwayland-1.17.1-14

have solved my problem
Comment 7 Peter Hutterer 2015-06-08 23:43:53 UTC 
Changing bug title to reduce confusion, "third button" in Xorg lingo means the right mouse button.
Comment 8 Clive Messer 2015-06-13 14:13:37 UTC 
Hmmm. Still middle button emulation still not working for me on a Dell e5530 laptop, even with those updates installed.

I will attach output from evemu-describe and evemu-record.

I see the same problem on a Dell Latitude E7240, using the latest updates available:

libinput-0.17.0-2.fc22.x86_64
xorg-x11-drv-libinput-0.10.0-5.fc22.x86_64

Fedora 21, which was installed until a few days ago on this laptop, worked fine with no special xorg configuration.

evemu-record output attached.

I'm not sure if the output of "xinput list-props" is helpful to a dev.....

[clivem@e5530 ~]$ xinput list-props 12

I'm supposing that if one of the props listed, (Ibut currently missing), was "libinput Middle Emulation Enabled" then it could be enabled by setting the property to "1"?

Also have this issue on another Dell e6320 laptop, freshly installed with F22, as well.

Let's move this to Bug 1227992 for the alps touchpads, it's a bit more precise (especially Hans' comment 12 there) and we can leave this bug alone and rest in peace :)
