AMD GPU não está em uso em 16.04

Question

eu tenho um problema. Minhas GPUs são Intel HD4400 e AMD Radeon HD8670m Depois de instalar o Ubuntu 16.04 e o kernel Linux 4.10.8 (nesta versão minha GPU é suportada) descobri que minha GPU não está em uso. Aqui está a saída de lspci | grep VGA e lspci | grep Display :

Desculpe pelo meu péssimo inglês.

    

Answer 1

Eu sou novo no Ubuntu e tenho um problema parecido com você. Tenho Intel HD 4000 e AMD Radeon HD8670m no meu laptop.

Após algumas pesquisas, você pode forçar o Ubuntu a rodar programas / jogos com placa gráfica AMD com DRI_PRIME

DRI_PRIME=1 ./EXECUTIBLE_PROGRAM

O engraçado é que, quando uso o glmark2 para verificar o desempenho, meu Intel HD 4000 teve um desempenho muito melhor do que minha placa de vídeo AMD usando o código abaixo

sudo apt-get glmark2
DRI_PRIME=0 glmark2
DRI_PRIME=1 glmark2

Eu obtive uma pontuação de 2000 para a Intel, apenas 700 para a AMD.
