Observe que minhas fontes de kernel não estão mais na árvore. Tento manter o kernel Eu construí o sistema com (preferência pessoal) e uso genkernel-next com o seguinte arquivo de configuração:

$ cat /etc/genkernel.conf \# Configuration file for genkernel # This file is sourced by genkernel at startup and determines which options # we will be using to compile our kernel.

Usando vlc com o nvidia driver proprietário e nenhum driver nouveau, não vi rasgo com vários DVDs – All Seasons of Breaking Bad e Oblivion, para citar alguns, e uma assinatura do Hulu para o Dr Who e outros no Chromium Stable. Eu também desativei a placa de vídeo onboard em favor da versão AGP da placa listada. Em 3 anos eu não tive que fazer nada importante, exceto algumas atualizações de disco rígido e substituir uma placa de rede sem fio

Eu estava tendo muitos problemas com NVidia no Arch. Tentei a sugestão nesta resposta à pergunta que você vinculou. Eliminou-a completamente para mim.

Isso é com o driver NVidia proprietário mais recente. Não vi nenhum rasgo perceptível desde no Mate (marco) e no LXDE ( openbox).

(se você quiser mais detalhes sobre meu sistema / configuração, me avise)
