I can't get button binding to work on a basic tilt-wheel mouse - I want to bind the scroll-wheel tilt-left & tilt-right buttons.
I've asked some specific questions below, but will be grateful for any info to help me understand libinput better.
I've been testing on clean Debian 12.4 KDE install with a Cherry MC-2000 mouse.
Issue 1:
System Settings → Input Devices → Mouse → Re-bind Additional Mouse Buttons
This does not detect the tilt-left and tilt-right clicks (I understand that by design left/middle/right buttons cannot be bound).
When I connected a 5-button Dell mouse, it could detect the extra side buttons but again not tilt-left/tilt-right.
Issue 2:
I manually added some bindings to ~/.config.kcminputrcThe bindings now appeared in System Settings → Input Devices → Mouse → Re-bind Additional Mouse Buttons.
On the 5 button mouse, the tilt left/right were now correctly sending "a" & "b", but not on the Cherry.
After some testing with libinput-tools, I noticed two differences between the two mice:
Difference 1: libinput list-devices
The 5-button Dell mouse has one device: {Dell Premium USB Optical Mouse}
The Cherry mouse has three devices: {Cherry USB Optical Mouse System Control, Cherry USB Optical Mouse, Cherry USB Optical Mouse Consumer Control}. These are marked as {keyboard, pointer, keyboard pointer} respectively.
![❓]()
Why does the simpler Cherry mouse have the extra devices?
![❓]()
Where are they configured (so I can potentially alter the capabilities and/or remove the extra devices)?
![❓]()
Is it possible to force the Cherry mouse to appear as a more generic mouse?
Difference 2: libinput debug-events (tested with ButtonRebinds removed)
Tilt-Left on Cherry generates one event:
event4 POINTER_SCROLL_WHEEL +8.112svert 0.00/0.0 horiz -15.00/-120.0* (wheel)
Tilt-Left on 5-button Dell generates three events:
event15 POINTER_SCROLL_WHEEL +23.104svert 0.00/0.0 horiz -15.00/-120.0* (wheel)
event15 POINTER_BUTTON +23.104s??? (281) pressed, seat count: 1
event15 POINTER_BUTTON +23.320s??? (281) released, seat count: 0
![❓]()
How can I get the Cherry mouse to also generate the POINTER_BUTTON events?
Here is more detailed testing output:
