Não é possível controlar a luz de fundo no Thinkpad P50 executando o trecho do Debian

2

Eu tenho um Thinkpad P50 executando a versão mais recente do Debian stretch. Meu ambiente de trabalho é mate.

Não consigo controlar a luz de fundo do meu laptop por nenhum meio. Não há interfaces de luz de fundo listadas em /sys/class/backlight/ e não tenho certeza de quais dispositivos em /sys/devices/ seriam o dispositivo correto a ser usado.

$ inxi -G

Alguma idéia de como fazer a luz de fundo funcionar?
