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 !
