basically each of the following: fn+f2 or fn+f3 (not even being recognised by evtest ) and the lid being closed or opened is being reported as “Event: time 1692812642.988180, type 1 (EV_KEY), code 238 (KEY_WLAN), value 1”.

so I though about remapping “Event: time 1692812642.988180, type 4 (EV_MSC), code 4 (MSC_SCAN), value d7” as the closing lid thingy

the same for fn+f2 and fn+f3 (increase and decrease brightness) I have to remap this “Event: time 1692812647.457821, type 4 (EV_MSC), code 4 (MSC_SCAN), value ab” so my question is I can remap the keyboard here 60-keyboard.hwdb but where can I remap the ev_msc stuff

basically all this to say I want to tell udev that the msc this with id d7 is actually the toggle for closing the lid and the msc thing with id ab are actually the two buttons that increase and decrease brightness and yeah that’s all

    so this is the output for the fn+f2/3 “[32752.594169] atkbd serio0: Use 'setkeycodes e02b ’ to make it known. [32752.599005] atkbd serio0: Unknown key released (translated set 2, code 0xab on isa0060/serio0).”

    and the output for the closing lid “[32780.534749] atkbd serio0: Use 'setkeycodes e058 ’ to make it known. [32780.538013] atkbd serio0: Unknown key released (translated set 2, code 0xd8 on isa0060/serio0).”

    my question is isn’t closing the lid is already assigned to “button/wlan WLAN 00000080 00000000 K” (output from acpi_listen)

    • so what should I do now
    • this part is actually unclear

    “You can find the appropriate evdev:* information by running sudo udevadm test /dev/input/eventX where eventX is the evdev fd for the device in question. evtest will show you the names.”

    basically how to actually do something like this MSC_KEY_d7=lid MSC_KEY_ab=brightness_thingies

    • yeah thanks

      You will notice that every keypress in evtest is also preceded by a KEY_MSC. This is just the evdev responding to a scancode. If the hwdb has this scancode pre-assigned in 60-keyboard.hwdb then it creates the EV_KEY event that is mapped. What you want to do is turn this EV_MSC into an EV_KEY by mapping the unknown scancode to a evdev event code using the hwdb file.

      The arch wiki has a good article on how to map these scancodes and identify what keycode you want to map. It is generic enough that it should work for most distros. Read all of section 2, it goes into specific detail about your question.
