I've just bought Lenovo X1 Carbon 5th gen (20HR) and installed Fedora 25.

The TrackPoint itself works out of the box but not the scrolling when you hold a middle mouse button.

xinput --list

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ xwayland-pointer:13                       id=6    [slave  pointer  (2)]
⎜   ↳ xwayland-relative-pointer:13              id=7    [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ xwayland-keyboard:13                      id=8    [slave  keyboard (3)]

find /dev/input/event* -exec udevadm info --attribute-walk --name={} \; | grep -e product -e name | sort -u

I found this option in dconf and tried to set any number but 0, does not affect anything. dconf

Comments is why that dconf setting doesn't do anything. It looks like a wayland composer issue. I dont think xserver has access to the middle button on wayland as wayland doesn't allow access to the hardware it wraps it and provides that. this is why you see xwayland-pointer:13 instead of 'ps/2-IBM-trackpoint' or something similar. I dont believe there's a way to get that button working without fixing the Wayland pointer first. I would love to be corrected though. I'll be reverting to a non wayland DE so I hope this gets fixed.

If you can find solution, or DE with working button, it will be very good for all lenovo users!

weird, this should definitely be enabled out of the box. check the output of sudo libinput-list-devices, it should list "Scroll methods: *button". If that's not the case, please file a bug against libinput.

I have new Lenovo ThinkPad E470 with Trackpoint and Fedora 26. But there is no option for enable middle button click scrolling.

So how to enable trackpoint? How to fix it?

Hi! Did you fix it? I'm in the same condition as yours and I don't know how to solve it.
