    Default Mouse wheel not working

    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:
    Code:
      polarisuse cris ~ 127 sudo hwinfo --mouse 
    [sudo] password di root: 
    60: PS/2 00.0: 10500 PS/2 Mouse 
      [Created at input.249] 
      Unique ID: AH6Q.oV6xZUCQFf1 
      Hardware Class: mouse 
      Model: "ImPS/2 Generic Wheel Mouse" 
      Vendor: 0x0002 
      Device: 0x0005 "ImPS/2 Generic Wheel Mouse" 
      Compatible to: int 0x0210 0x0013 
      Device File: /dev/input/mice (/dev/input/mouse0) 
      Device Files: /dev/input/mice, /dev/input/mouse0, /dev/input/event1, /dev/input/by-path/platform-i8042-serio-1-event-mouse, /dev/input/by-path/platform-i8042-serio-1-mouse 
      Device Number: char 13:63 (char 13:32) 
      Driver Info #0: 
        Buttons: 3 
        Wheels: 1 
        XFree86 Protocol: explorerps/2 
        GPM Protocol: exps2 
      Config Status: cfg=no, avail=yes, need=no, active=unknown
    
    What can I do to solve this problem?

    Thank you in advance

    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?
    Code:
    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.

    Ouch! You're probably right! :-(

    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:
    Code:
    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.
