Alterar dispositivo GPU padrão para Xorg / GDM após PCI Passthrough?

0

O dispositivo Intel Corporation HD Graphics 510 deve ser usado para o sistema host do Ubuntu.

O dispositivo NVIDIA Corporation GP107 foi reservado para uso do KVM.

O sistema host Ubuntu não pode usar corretamente o Intel Corporation HD Graphics 510 para se conectar ao servidor X. Podemos contornar isso?

O comando sudo systemctl start gdm fará com que o TTY pisque continuamente e seja difícil de usar.

sudo cat / etc / default / grub | grep CMDLINE

Bem, parece que o Xorg está tentando usar a placa NVIDIA mesmo assim. Você tentou especificar qual GPU Xorg deve usar ?

X does not start after enabling vfio_pci

This is related to the host GPU being detected as a secondary GPU, which causes X to fail/crash when it tries to load a driver for the guest GPU. To circumvent this, a Xorg configuration file specifying the BusID for the host GPU is required. The correct BusID can be acquired from lspci or the Xorg log. Source →

/etc/X11/xorg.conf.d/10-intel.conf

Section "Device"
        Identifier "Intel GPU"
        Driver "modesetting"
        BusID  "PCI:0:2:0"
EndSection

Se xorg.conf.d ainda não existir, basta criá-lo.

Depois disso, o Xorg não deve mais tentar usar a placa gráfica NVIDIA. A página Wiki do Arch lista outros problemas que você pode achar interessantes à medida que avança.
