Unusable open souce driver ATI no Debian Jessie

Question

Antecedentes

Agora sou forçado a usar o driver proprietário de código-fonte aberto ( radeon kernel module), pois após a última atualização, obtive o Xorg versão 7.7 e fglrx simplesmente não o suporta.

Para o uso normal da área de trabalho este driver funciona bem, melhor que fglrx , eu ainda tenho consoles de buffer de quadro de alta resolução! ^ _ ^

Problema

Mas quando os recursos reais do OpenGL são usados, por exemplo, jogos de vídeo ou até mesmo reprodução de filmes com o VLC, a tela congela em um tempo e um número de pixels vermelhos ou azuis aparecem. Agora, se eu tiver sorte, isso dura por alguns segundos, então o monitor perde o sinal e de repente tudo restaura; se eu não sou, eu tenho que reiniciar ...

Answer 1

Eu finalmente encontrei uma solução em este tópico do fórum .

Em suma, há um parâmetro de inicialização para definir ( radeon.dpm ), então corrigi a edição de /etc/default/grub para algo como:

GRUB_CMDLINE_LINUX_DEFAULT="quiet radeon.dpm=1"

Então, sudo update-grub e reinicialize.
