ASUS TUF A15 GTX 1660 ti on Ubuntu 18.04 fresh install, black screen when booting + unknown display device

Meanwhile, I followed some suggestions on this forum topic:

  • delete /etc/X11/xorg.conf (it didn’t exist for me)
  • make sure nvidia-prime is installed (sudo apt install --reinstall nvidia-prime)
  • switch to nvidia (sudo prime-select nvidia)
  • remove stray blacklist files (sudo rm /lib/modprobe.d/blacklist-nvidia.conf /etc/modprobe.d/blacklist-nvidia.conf)
  • update the initrd (sudo update-initramfs -u)
  • reboot

plus changed options nvidia-drm modeset=1 to options nvidia-drm modeset=0 in /lib/modprobe.d/nvidia-kms.conf.

Also added the kernel parameters acpi_osi=! acpi_osi=Windows\ 2009

The system did not stick in the black screen at boot and nvidia-smi produces a sensible output:

However, nvidia-settings shows an empty window and the system still does not recognize my main display device.
