Fedora 42: Thinkpad Keyboard 2 ability to middle click and scroll lost in yesterday's updates

Ask Fedora
1

Middle click to scroll was working as expected until yesterday’s updates. Now it does nothing. I tried windows and a Linux mint live CD, and it
works as expected. I do not know which update caused this. The functionality is also lost on Hyperlnd, so I suspect a Wayland or kernel regression:

sudo libinput debug-events doesn’t register anything once I depress the middle mouse button on Fedora 42.
I would appreciate any help in trying to debug this as this keyboard is my main input device, and middle click to scroll is very desireable.

I can confirm this. The updates I made this morning broke the functionality, but there were a lot, so it’s not easy to pinpoint which one caused this:

I’ll try downgrading libinput and see what happens. It seems like an obvious candidate for such a thing.

I don’t have exactly the same issue, but maybe this is related.

In the last few days, there were a couple of times where I did a dnf updates that upgraded KDE components, and then left-click stopped working in a device-agnostic way (tapping my touchpad, clicking the button below my touchpad, and left clicking the button on a USB mouse - none of these were recognised).

Fortunately for me, that was fixed by a reboot. (I didn’t check whether logging out and back into my session without a reboot worked.)

This was on an Asus laptop, not a Thinkpad - though the fact that a USB mouse was affected makes me think it wasn’t device-specific.

Downgrading from libinput 1.28.901 to 1.28.0 fixed the problem:

sudo dnf install libinput-1.28.0-1.fc42

1.28.0 was the only earlier version I was able to find with dnf:

dnf4 --showduplicates list libinput

There’s also 1.28.1 in between these two releases, but someone would have to build that from source and see if the bug is already present in that one.

Edit: Oh, a bug has already been filed upstream :slight_smile:

Fixed in libinput-1.28.901-2.fc42 now (and by “now” I mean whenever the ppc64le build finishes…)

Awesome! :smiling_face_with_three_hearts:

Thanks, I downgraded as the update hasn’t yet materialized on my mirror. Things are back to how they should be. Thanks everyone!
