Package: libinput10
Version: 1.2.4-1
Severity: normal
This looks like an upstream bug. I have the following devices
on my Dell Latitude E6540:
---
$ xinput list | grep Alps
⎜ ↳ AlpsPS/2 ALPS DualPoint TouchPad id=13 [slave pointer (2)]
⎜ ↳ AlpsPS/2 ALPS DualPoint Stick id=14 [slave pointer (2)]
X is using libinput:
---
$ grep Alps /var/log/Xorg.0.log | grep 'Using input driver'
[ 37.977] (II) Using input driver 'libinput' for 'AlpsPS/2 ALPS DualPoint
TouchPad'
[ 38.000] (II) Using input driver 'libinput' for 'AlpsPS/2 ALPS DualPoint
Stick'
The problem started after upgrading yesterday from libinput 1.2.3 to
1.2.4.
I checked out the upstream repo from:
---
git://anongit.freedesktop.org/git/wayland/libinput
and see quite a lot of recent work by Peter Hutterer around middle mouse
button emulation:

I have a feeling those commits may have broken or changed something. As
far as I can tell, it should be working:
---
$ xinput get-button-map 13
1 2 3 4 5 6 7
But using either xev or "xinput query-state 13", I can never get button
2 to show up, only buttons 1 and 3. It's worth noting that button 2
works fine for my Stick device (it has a separate row of three buttons
directly above my trackpad). However, I'm so accustom to using the
emulated middle mouse by using the left and right buttons of my
trackpad, I seemed to have completely forgotten about the still
functioning buttons above the trackpad. It's a decent workaround for
the time being anyway.
Here is a list of properties from my trackpad. I would expect
to have seen something about middle mouse button emulation here, but I'm
not entirely sure what it looked like before:

I think that's all the relevant stuff. Let me know if anything
else is required.
