Estou configurando o arch linux por alguns dias - na maioria das vezes, é fácil progredir, mas estou tendo um problema real com o suporte a multiheads.
Eu tenho um Thinkpad X1 extreme com um chip de vídeo Intel e NVIDIA e gráficos híbridos
Eu instalei:
- xf86-video-intel
- xf86-video-vesa
- bumblebee
- bbswitch
- lightdm
- i3wm
Este é o xorg conf que estou usando:

Esta é a saída lspci -v dos dois dispositivos de vídeo:

Quando eu inicializo, o X parece pegar o layout e as telas bem (anteriormente eu tive dificuldade em fazê-lo ler além da primeira seção da tela):

( pastebin de todo o Xorg.0.log )
e bbswitch parece reconhecer e gerenciar os dois dispositivos de vídeo, embora com algum tipo de problema:
[ 2.272033] bbswitch: loading out-of-tree module taints kernel.
[ 2.272053] bbswitch: module verification failed: signature and/or required key missing - tainting kernel

[ 2.272526] bbswitch: Succesfully loaded. Discrete card 0000:01:00.0 is on
[ 2.276310] bbswitch: disabling discrete graphics
( pastebin de toda a saída do dmesg )
mas ainda assim, xrandr e xrandr --listproviders mostram apenas 1 tela e 1 provedor:
$ xrandr

eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 194mm

...
$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x43 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 3 outputs: 1 associated providers: 0 name:Intel
Eu não posso usar o xrandr para ligar ou mover telas porque a saída não está disponível após a inicialização (se um monitor está conectado ou não)
