AMD Graphics
The opensource AMDGPU drivers work correctly with no special modification.
Fingerprint Reader
Fingerprint sensor 06cb:00bd is not supported by fprint right now. There is some talk of an upcoming driver.[1][2]
Backlight
Backlight works correctly by manipulating the values, between 0-255, inside /sys/class/backlight/amdgpu_bl0/brightness
or using a backlight managing utility.
systemd-backlight@backlight:acpi_video0.service
requires masking as it seems to be triggered and fails on boot.
Smartcard Reader
Seems to work and read cards. Following instructions from smartcards.
