Depois de reiniciar a minha máquina Ubuntu 14.04, não consegui entrar no Unity novamente e tive que voltar atrás no Gnome. Eu descobri que há algo errado com o GLX desde quando eu corro:
/usr/lib/nux/unity_support_test -p
Recebo a seguinte mensagem:
Error: GLX is not available on the system
Além disso, (partes relevantes de) a saída de menos /var/log/Xorg.0.log se parece com isso:

Eu já tentei reinstalar o driver NVidia (346.82) e também tentei com uma versão mais nova (355.06), mas não consegui resolver o problema. Além disso, não consigo reproduzir nenhum tipo de vídeo que usei sem problemas.
Como posso fazer o GLX funcionar corretamente de novo?
EDITAR:
Além disso, aqui está a saída de glxinfo no terminal:
Error: couldn't find RGB GLX visual or fbconfig
Acho que isso confirma que o GLX não funciona. Além disso, quando executo nvidia-settings , sob informações OpenGL / GLX , vejo:
Failed to query the GLX server vendor.
