A instalação My Mythbuntu (baseada no Ubuntu 12.04), que está sendo executada sem problemas há anos, de repente não inicia o X Windows depois de executar um simples apt-get upgrade . Vários pacotes foram atualizados, mas os relevantes de /var/log/dpkg.log parecem ser:

O PC contém uma placa de vídeo integrada da Intel (Controladora Gráfica Integrada do Chipset Série 4 da Intel Corporation (rev 03)) e uma placa sintonizadora HD-5500 HDTV (Conexant Systems, Inc. CX23880 / 1/2/3 Vídeo PCI e Decodificador de Áudio (rev 05)).
Não há arquivo /etc/X11/xorg.conf .
Até agora, tentei o seguinte:
Fazendo downgrade para um kernel Linux mais antigo:
apt-get install linux-generic=3.2.0.45.54
Fazendo downgrade de lightdm :
apt-get install lightdm=1.2.1-0ubuntu1
X -configure e reiniciando (excluí a xorg.conf gerada depois de não funcionar) Até agora, parece que recebo o mesmo erro, não importa o que eu faça. Alguma sugestão?
No caso de alguém se deparar com este problema, eu fui capaz de consertá-lo mudando para o PPA experimental de drivers de placa de vídeo xorg-edgers, e instalando o unity-2d da seguinte forma:
sudo apt-add-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install unity-2d
Use isso em PPAs xorg-edgers aqui .
Acho que os drivers gráficos da Intel são instalados durante a instalação do sistema operacional.
Seu problema é que você precisa das bibliotecas para compactação de textura instaladas - elas não são instaladas por padrão devido a problemas de direitos autorais. Eles são necessários para quase todos os jogos 3D. Com as bibliotecas faltando, suspeito que o jogo acha que os pilotos não estão lá porque o jogo está procurando por suporte ao S3TC. Sem as bibliotecas, o cartão não anunciará o suporte do S3TC, portanto, o jogo irá falhar.
A execução do seguinte instalará as bibliotecas:
sudo apt-get install libtxc-dxtn-s2tc0
ou apenas procure por libtxc-dxtn-s2tc0 no Centro de Software.
Esta correção não apresenta nenhum risco ... testada por mim várias vezes. Espero que te ajude .... ... fique à vontade para comentar suas perguntas ...
