Nvidia GeForce GT 710

Is no longer supported by video-nvidia that is the 490xxx version family.

@moqret

the system said that 470xx does not exist.

We need the exact commands you used and the exact error you got.
This should help

Nvidia 495xx driver series drops Kepler support; need to manually switch to 470xx.

mhwd’s video-nvidia now provides 495xx; if you need 470xx you must manually switch before updating, by using the commands below.

With the new 495xx driver series a lot of Wayland adjustments got added. Also Nvidia decided to remove Kepler support . Therefore you may want to switch drivers to 470xx series, which still supports those graphic cards:

sudo mhwd -r pci video-nvidia
sudo mhwd -i pci video-nvidia-470xx

Nvidia 340xx driver series no longer works.

This driver is end of life by NVIDIA, you should not be using it as there are serious security issues with this driver. You have to either get newer supported hardware or switch to Nouveau:

#remove old
sudo mhwd -r pci video-nvidia-340xx
sudo mhwd -r pci video-linux
#install new nouveau
sudo mhwd -i pci video-linux

Reboot after and you're done.

But since you have a dual GPU on a Desktop, is there any Monitor connected to the AMD one? If not, why would you add the amdgpu module to mkinitcpio.conf ?
