não consigo ajustar o brilho
Tenho um MSI GT72VR portátil com APENAS 1 placa gráfica , uma NVIDIA GeForce GTX 1060 Mobile e 2 placa de áudio , uma NVIDIA GP106 e uma Intel CM238 .
O problema é que não consigo ajustar o brilho da minha tela. Sempre é 100%. Eu tenho Ubuntu 18.04 drivers de instalação limpa e nouveau (Xorg.org)
