[Solved] TrackPoint Middle Click stopped working (after update)

Folks,

yesterday, I played with locales and upgraded my system afterwards. Now, the middle-click function of my TrackPoint is not working anymore (no scrolling, no clicking). I'm on a ThinkPad x1 carbon gen5.
I spent the whole morning searching for solutions, but couldn't really distinguish, what applied to me and what not.

I deleted all udev rules (rules.d and hwdb.d)
my .xinitrc is empty except for xbindkeys

The TrackPoint pops up in xinit and libinput

# xinput list

note that the Trackpoint is called TTPS/2 IMB Trackpoint. I think that before the update it was PPS/2 Generic Mouse

libinput debug-gui does not recognize middle click.
I checked if the hardware might be broken by running an ubuntu installation media, in which middle click worked fine.
I installed gpointing-device-settings and tried to set the TrackPoint up that way without success.

for info, I run Plasma 5, the input device settings in system settings do not affect the Trackpoint at all.
Any suggestions?
I guess the solution to getting the TrackPoint working again might be quite easy, I just can't see it.

Thank you for your help.

edit:
maybe this is of relevance, too:

# dmesg | grep TrackPoint

Same for me. I think this is a kernel bug, there are some issues on it. Looks like it's been merged recently into master. https://bugzilla.kernel.org/show_bug.cgi?id=196253

I also had the same issue. Referring to above Bugzilla link, the fix seems to be merged already.
After I switched to the newer kernel (4.11.12), the middle-button works now.
Thanks for your information!
