Eu li que o VirtualBox mais recente suporta convidados Linux com monitores duplos. Consigo que dois monitores sejam iniciados quando inicio minha Arch VM, mas não consigo fazer com que o Xorg abranja o segundo monitor. Eles são exibidos constantemente no modo clone. Alguém fez isso com sucesso? Se sim, você poderia compartilhar seu xorg.conf?
Edit: meu xorg.conf (eu tentei BusID incremental como teste, mas eles tinham o mesmo antes).
