Estou executando o xUbuntu 16.04 em um dispositivo asus com um processador AMD A6-7310. O problema é que não posso suspender o computador. Quando coloco a tela no teclado, a tela fica preta, mas os ventiladores ainda estão funcionando, assim como a luz de fundo. Quando eu abro a tela de volta, a tela ainda está preta, a luz de fundo para e as ventoinhas ainda estão funcionando. Então, preciso pressionar um botão para voltar à tela de login que aparece em um segundo.
Você sabe como posso resolver meu problema? Tentei definir a opção "nomodeset" durante a inicialização, mas o problema ainda é o mesmo.
Obrigado!

EDITAR
Eu tentei definir em /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012'"
e então eu corri sudo update-grub
e reiniciei, mas o problema é o mesmo depois ...
