Ubuntu 14.04 congela aleatoriamente (DRM)

Question

Esse congelamento aleatório está acontecendo há meses. Eu acredito que o problema está no Direct Rendering Manager (DRM).

Do registro do kernel:

O congelamento acontece nestes:

dalius@PC1124:~$ cat /var/log/kern.log | grep drm | grep hang
Sep  8 18:21:25 PC1124 kernel: [ 3497.804013] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... render ring idle
Sep 11 08:34:45 PC1124 kernel: [84264.804020] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... render ring idle

Depois disso, não consigo alternar para tty1-tty6. Eu vejo principalmente tela de login congelado, mas isso aconteceu durante o uso normal (principalmente ao usar alt + tab). A única solução é a reinicialização difícil. Descobri o REISUB e tentarei da próxima vez que isso acontecer.

A Intel está fornecendo há algum tempo uma seção especial para drivers Linux para seu hardware, e eu acho que você deve experimentar o mais recente Instalador Gráficos 1.0.6 para Ubuntu * 14.04, 64-bit ou Instalador de Gráficos 1.0.6 para Ubuntu * 14.04, 32-bit que pode ser encontrado nesta página .

Você também pode estar interessado em outros utilitários nessa página, como Mesa - 10.2.2 ou Intel-gpu-tools - 1.7 .

Eu não posso prometer que o instalador de Gráficos para o Ubuntu 14.04 funcionará porque eu nunca testei, mas desde que a Intel o colocou lá, eu suponho que deva funcionar.
