MX Master 3S gesture button not remappable (BTN_FORWARD only, no key events)

[brokkoli71]

Hi, thanks for the tool :) I tried to use the thumb button of the MX Master 3S to scroll through workspaces. Maybe its a fault on my end but I did not manage to get this working.

Summary

On an Omarchy (Hyprland/Wayland) system, the MX Master 3S gesture (thumb) button only emits BTN_FORWARD pointer events. logiops does not remap the gesture button to keypresses or gestures, even when mapping multiple CIDs to keypresses. As a result, no key events appear in wev and Hyprland never receives the configured key combos.

Environment:

• Distro: Omarchy (Arch-based)
• DE/WM: Hyprland (Wayland)
• logiops/logid: v0.3.5
• Connection: Logitech USB receiver (detected at /dev/hidraw2)
• Device: "MX Master 3S"

logid -v output:

[INFO] Detected receiver at /dev/hidraw2
[INFO] Device found: MX Master 3S on /dev/hidraw2:3
[DEBUG] /dev/hidraw2:3 remappable buttons:
[DEBUG] CID  | reprog? | fn key? | mouse key? | gesture support?
[DEBUG] 0x50 |         |         | YES        |

[DEBUG] 0xc4 | YES     |         | YES        | YES
[DEBUG] 0xd7 | YES     |         |            | YES

Test config (no gestures, simple keypress to identify CID):

devices: (
{
    name: "MX Master 3S";
    buttons: (
        { cid: 0x52; action = { type: "Keypress"; keys: ["KEY_F13"]; }; },
        { cid: 0x53; action = { type: "Keypress"; keys: ["KEY_F14"]; }; },
        { cid: 0x56; action = { type: "Keypress"; keys: ["KEY_F15"]; }; },
        { cid: 0xc3; action = { type: "Keypress"; keys: ["KEY_F16"]; }; },
        { cid: 0xc4; action = { type: "Keypress"; keys: ["KEY_F17"]; }; },
        { cid: 0xd7; action = { type: "Keypress"; keys: ["KEY_F18"]; }; }
    );
}
);

Steps to reproduce:

1. Set the above config in /etc/logid.cfg
2. Restart logid: sudo systemctl restart logid
3. Run wev
4. Press the MX Master 3S gesture (thumb) button

Expected:

• wev shows one of F13–F18 keypress events (confirming the CID mapping), or
• gestures defined on the CID produce keypress events.

Actual:

• wev shows only pointer events for BTN_FORWARD (button 277), no keypress events:
  [wl_pointer] button: ... button: 277 (forward), state: 1/0
