Black screen when switching to AMD card

Hi, thanks a lot for your help, I managed to partially settle the issue. I had to go through additional steps though, here is the summary in case it could be useful:

  • Boot with NVIDIA
  • Remove /etc/X11/xorg.conf.d/90-nvidia.conf
  • Shutdown
  • Replace the GPU with AMD
  • Reboot → failed, stuck at loading page
  • Reboot to fallback initramfs
  • Create /etc/X11/xorg.conf.d/10-amdgpu.conf as explained here Switching out nVidia GPU for AMD GPU - #2 by megavolt
  • Reboot → failed, stuck at loading page
  • Reboot to fallback initramfs
  • Rebuild mkinitcpio -P (I am not sure if I needed to reboot before this step)
  • Reboot → OK !

However, I still have this shows:

Graphics:
  Device-1: AMD Navi 23 [Radeon RX 6600/6600 XT/6600M] driver: amdgpu
    v: kernel
  Display: x11 server: X.Org v: 21.1.13 with: Xwayland v: 24.1.0 driver: X:
    loaded: modesetting dri: radeonsi gpu: amdgpu 

Is that normal to have modsetting loaded ?
also, it seems my system does not recognize my screen properly
I cannot set the refresh rate at 144Hz, and I do not see any G-sync option
another driver issue ?

Edit: I will close this topics as I can now login.
and will open another another that concerns the AMD driver specifically.
Thanks again !
