Kubuntu 16.04 falha do sistema regularmente [fechado]

Question

Por algumas semanas, meu kubuntu instala falhas regularmente. Tudo congela completamente. Nenhum momento do cursor do mouse, nada. Na maioria das vezes que isso acontece, minha máquina está executando uma pesada tarefa de nó. 1 dos 4 núcleos está em 100%.

Eu tentei vários kernels diferentes, mas isso não parece ter nenhum efeito.

$ uname -r 4.11.4-041104-genérico

A versão do meu bios é: 1.4.17

Aqui está um log do sistema quando aconteceu: (neste caso aconteceu ao reproduzir um vídeo do youtube)

Answer 1

Parecia ser um problema no kernel. Depois de instalar: 4.11.11-041111-genérico tudo era bom. Tem sido executado por 2 meses, não há mais falhas. ; -)

Thx Javier para você ajudar!

respeita, Billy

    

Answer 2

Com certeza você tem um problema com o driver de vídeo.

Experimente a imagem do ubuntu 14.04 do dell support

Se o problema persistir em 14.04 talvez quente? Seu modelo é xps 13 9350?

Eu vejo que a nova instalação não é carregada 14.04. talvez quando atualizar o driver o sistema começa a congelar.

tente mudar o driver proprietário.

Depois de instalar os drivers nvidia, muitos aplicativos gráficos não lançar

feito?
