  Device-1: NVIDIA TU117M vendor: Lenovo driver: nvidia v: 470.63.01 
  alternate: nouveau,nvidia_drm bus-ID: 01:00.0 chip-ID: 10de:1f99

  Device-2: AMD Renoir vendor: Lenovo driver: amdgpu v: kernel bus-ID: 05:00.0

Ah I see… a hybrid GPU…

It loads first amdgpu and then nvidia:

So it must be the so called “timing issue”. Try this:

Still booting to blank screen

Looks like a timing issue… make the drivers load very early: Replace MODULES=() with: MODULES=(amdgpu nvidia) at /etc/mkinitcpio.conf Then run sudo mkinitcpio -P to update the initramfs. Reason of this is that the driver scheduled late and therefore the display-manager does not start at first time when switching from basic video mode to the graphical mode
