## 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.
