[Bug 2149765] [NEW] Menu key broken: hwdb maps scancode 0x70072 to unknown, suppressing both Fn and Menu

[Faré]

Public bug reported:

I upgraded my apt packages, and the Menu key stopped working, because of ubuntu-x1e-settings-nogrub now has a file /usr/lib/udev/hwdb.d/61-ubuntu-x1e-settings.hwdb containing
evdev:name:hid-over-i2c 04F3:000D Keyboard:dmi:bvn*:bvr*:bd*:svnLENOVO:pn21N1*:*
evdev:name:hid-over-i2c 04F3:000D Keyboard:dmi:bvn*:bvr*:bd*:svnLENOVO:pn21N2*:*
 KEYBOARD_KEY_70072=unknown # Silence spurrious F23 key-press report from Fn key

unknown is too strong. Can we have it be compose like it seems to have
been before?

Looks like the Menu key is mapped to Hyper_L Shift_L 70072
while somehow the Fn key is mapped to Control_L 70072

Please don't kill the Menu key! Maybe make that an option, or a separate package, or something.

Claude suggests using keyd to handle things at the evdev level:
/etc/keyd/thinkpad-t14s.conf
[ids]
0018:04f3:000d

[main]
# Menu key combo → compose
leftmeta+leftshift+compose = compose

# Fn key (Ctrl+0x70072) → nothing
leftctrl+compose = noop

# We probably should try to not break things on any other machine that would somehow use the same chipset but different firmware
compose = compose
