Moving smoothly from Nvidia GPU to AMD

Hi,

I plan on switching to AMD GPU (RX 6700XT) on my arch system. (AMD 5800X + GTX 1070)  with following layers for booting into graphical Xorg / lighdm / awesomwm.

I'am not sure about the correct way of doing it.

My current plan is :
- pacman -Qs nvidia
- pacman -Rns every packets from the command above
- Power down computer.
- Switching the cards.
- Power on the system.
- Pray it boots ?

Any optimization or corrections ?

Re: Moving smoothly from Nvidia GPU to AMD

Remove a potentially generated /etc/X11/xorg.conf as stuff generated by nvidia-xconfig for example will hard ref the nvidia card and fail the xorg start, if you don't have xorg configs in /etc/X11/ that set a Device for the nvidia card the outlined approach should generally work. What you probably want to do since an -Rns can pull a bunch of stuff is install vulkan-radeon;lib32-vulkan-radeon so that e.g. steam's requirement for a vulkan provider is satisfied even if lib32-nvidia-utils is removed.
