I had the same problem, the solution is here: https://community.frame.work/t/12th-gen-not-sending-xf86monb...
You can enable the hotkey support by blacklisting the hid-sensor-hub driver: vi /etc/modprobe.d/framework-als-blacklist.conf Add the following: blacklist hid-sensor-hub And then restart
It worked, but it needed `hid_sensor_hub` with underscores! and `sudo update-initramfs -u` before the reboot
