Package: udev
Version: 241-7~deb10u1
Severity: normal

Dear Maintainer,

typical laptop 'extra' keys aren't properly working, both dim and
brighter buttons get registered identical as mic on/off. I've checked
upstream's git changes:
https://github.com/systemd/systemd/commits/master/hwdb/60-keyboard.hwdb
(and they moved the file last month, checked there too). Latest Bios,
using default Wayland/Gnome.

sudo showkey -s
kb mode was ?UNKNOWN?
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
0x9c
0x5a 0xda
0x5a 0xda
0x5a 0xda

When doing this, nothing gets output, but gnome shows the mic on/off:

sudo evtest /dev/input/event5
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x0 product 0x0 version 0x0
Input device name: "HP WMI hotkeys"
Supported events:
Event type 0 (EV_SYN)
Event type 1 (EV_KEY)
Event code 138 (KEY_HELP)
Event code 141 (KEY_SETUP)
Event code 148 (KEY_PROG1)
Event code 153 (KEY_DIRECTION)
Event code 224 (KEY_BRIGHTNESSDOWN)
Event code 225 (KEY_BRIGHTNESSUP)
Event code 226 (KEY_MEDIA)
Event code 240 (KEY_UNKNOWN)
Event code 358 (KEY_INFO)
Event type 4 (EV_MSC)
Event code 4 (MSC_SCAN)
Event type 5 (EV_SW)
Properties:
Testing ... (interrupt to exit)

I've given it a try with Qubes on X instead of Wayland, tried without an
X-server: all the same, not sure how to debug further.

What do you get in the kernel log/journal if you press the
brightness up/brightness down key?

What happens if you run evtest (as root) and you press one of those keys?

Nothing in dmesg, /var/log/syslog, also not with journalctl -f.
I already gave the (empty) output of evtest, here's when using the
event0:
I hit dim, brighter, mic off buttons, located at f3, f4 and f8.

Assuming KEY_F20 is your brightness up or down key, you should try to
remap this to brightnessup or brightnessdown

You can follow the instructions at
https://wiki.archlinux.org/index.php/Map_scancodes_to_keycodes

I hit 3 different keys, but they all gave identical evtest/keyscan
outputs. So remapping will give me the bug 'only brightness up' or 'only
brightness down.'
