O sistema trava (a tela não é atualizada) ao jogar videogames 'pesados'

Question

aparentemente meu sistema está travando (por exemplo, a tela está congelada, mas eu posso conectar via ssh - kill -9 -1 não mata todos os meus processos) quando eu jogo videogames intensivos / benchmarks 3D ( SC2 , HoN e o Unigine Valley benchmark).

O que eu experimentei até agora é que aparentemente a GPU ( nVidia 470 GTX ) dispara para 91+ graus de temperatura. Se eu mantiver o caso aberto, esse comportamento geralmente não acontece.

O que você acha que é? É minha GPU bruned e não tolera mais altas temperaturas?

Estou usando o Ubuntu 12.04 (x86-64) e o driver nVidia 310.14.

Felicidades

    

Answer 1

Parece que é um bug acionado no driver da nVidia (procurando em /var/log/kern.log ):

Estou tentando a versão 304.88 dos drivers nVidia e até agora parece bem ...
