Mouse wheel not working

English Hardware
#1

Hi, since a few days my mouse wheel is not working anymore for scrolling.

If I push it (using it as the central mouse button) it works. But it does not work to scroll.

The scroll wheel is, however, recognized:

Hmm…I guessing that since TW is bleeding edge there may have been recent libinput behaviour changes (deliberate or possible regressions).
Anyway, what is reported by the libinput itself?

libinput list-devices

Which desktop environment?

Don’t discount the possibility that the mouse is just broken, I have had several mice fail like that.

Hi gogalthorp!

Ouch! You’re probably right! :frowning:

After reading your message I connected another USB mouse (which I know it works, because this is the one I usually use with my laptop) and the wheel is working correctly!

Here is what libinput says about the working mouse:

Device:           Logitech M187
Kernel:           /dev/input/event12
Group:            4
Seat:             seat0, default
Capabilities:     keyboard pointer  
Tap-to-click:     n/a
Tap-and-drag:     n/a
Tap drag lock:    n/a
Left-handed:      disabled
Nat.scrolling:    disabled
Middle emulation: disabled
Calibration:      n/a
Scroll methods:   button
Click methods:    none
Disable-w-typing: n/a
Accel profiles:   flat *adaptive
Rotation:         n/a

To me, it seems identical to the other one, let alone the added “keyboard” capability (don’t know what it means).

Thank you!

Ok, so hardware fault. No need to pursue further.
