Normalmente o X requer driver para o controlador de vídeo para fornecer o
ambiente gráfico. Apesar de ser possível acionar o X com o driver VESA do
kernel, o recomendado é usar o próprio driver do X porque é otimizado e
aproveita melhor os recursos do controlador de vídeo.

Não tem problema, até é melhor assim. Eu removi as partes que não importam
no momento.

Resumindo, o driver "intel" está sendo carregado e detecta perfeitamente a
sua controladora de vídeo. Entretanto não ativa o GLX, ao que me parece
por falta de um arquivo.
Eu tive um problema semelhante, se não me falha a memória era porque a
biblioteca mesa não fora instalada corretamente. Verifique se no seu
sistema está instalado o pacote "libgl1-mesa-glx". Se não estiver,
instale-o e reinicialize o X.
Para testar o GLX, digite o seguinte comando no shell:
$ glxgears -info
e veja se o OpenGl da Intel está funcionando.
