Eu sou dual boot 8 e Ubuntu no Yoga 3 Pro. Eu tive os mesmos problemas que outros usuários:
ideapad_laptop . Alguma ideia? Fico feliz em fornecer qualquer informação que possa ajudar a restringir isso.
Aqui está o resultado do script sem fio:
Nota: a saída do script mostra wl em /etc/modules , mas adicionei manualmente, quando executo sudo modprobe wl , recebo modprobe: FATAL: Module wl not found. .

Antes de continuarmos, tenha certeza de que ideapad-laptop está funcionando como esperado. De um terminal:
sudo modprobe ideapad-laptop
Agora, o seu comutador sem fio e o touchpad / touchscreen funcionam como esperado? Em caso afirmativo, remova a lista negra que você adicionou anteriormente. Agora para o wireless:
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl
Por favor, note e poste qualquer erro.
