Acabei de instalar o Ubuntu 16.04 LTS na minha Asus (memória de 7,7 GiB, processador Intel 5Y10 CPU a 0,80 Ghzx4, gráficos Intel HD 5300 (broadwell Gt2), 64 bits, 117,5 GB).
Após 5 a 15 minutos de uso, o Wi-Fi é desligado, mas também a capacidade de usar qualquer comando sudo no terminal. Depois de uma reinicialização, normalmente funciona novamente, mas às vezes duas reinicializações são necessárias antes que eu possa aproveitar o Ubuntu por 5-15 min novamente.
Primeiro, pensei que era apenas um problema de Wi-Fi, mas parece estar mais relacionado a uma perda de privilégios administrativos?
Foi solucionada por 2 dias e até mesmo reinstalada uma vez.
Alguma idéia?

Resolvido.
Analisamos cuidadosamente o /var/log/syslog (graças ao mikewhatever) e descobrimos que o kernel pode não ser o mais adequado ( --end trace--- error).
Mudou de uma versão 4.10 para uma versão 4.4 e está funcionando perfeitamente agora, isso resolveu todos os problemas mencionados acima.
