Eu tenho um laptop Asus N56VM, com gráficos otimizados (Intel + Nvidia). Ele tem uma conexão HDMI e eu tenho um monitor conectado a ele. No Windows, eu posso ter dois monitores, e também posso no Ubuntu, sem nenhum problema.
Meu problema é que estou tentando fazer com que funcione no Debian, e não tenho idéia de como. Eu acho que é algum problema de driver ou kernel, porque o xrandr nem sequer detecta a saída HDMI. Funciona mesmo em lightdm ou slim.
Aqui está o que eu tenho rodando xrandr no Ubuntu:

O que posso fazer para mudar isso?
Estou na mesma posição. Eu tenho Dell e6430. Na casa de hortelã 17.3, não foi um problema tê-lo funcionando. Mesmo nas configurações da nvidia, eu poderia escolher entre usar o Primus ou não. No Debian a única solução que funciona para eu ter saída da Nvidia no HDIMI é desabilitar o Optimus no BIOS.
