Problema com o NVIDIA Optimus depois de suspender no Debian 9

0

Comprei um computador portátil ASUS com tecnologia Optimus. Instalei o Debian 9 e tudo funciona bem, exceto que, depois de suspender o sistema, não consigo iniciar nenhum aplicativo com optirun ou primusrun ... para que funcione. precisa reiniciar o sistema inteiro.

O arquivo de log ( /var/log/Xorg.8.log ) mostra:

# cat /var/log/Xorg.8.log | egrep "(EE)|(WW)"
