QEMU GPU Passthrough

Fix to free screen (via sudo):

#!/bin/bash
echo 0 > /sys/class/vtconsole/vtcon0/bind
echo 0 > /sys/class/vtconsole/vtcon1/bind
echo efi-framebuffer.0 > /sys/bus/platform/drivers/efi-framebuffer/unbind
  • EFI: disable secure boot
  • make sure AppArmor is not prohibiting file access to dirs necessary for saving nvram
