Installing from aur legacy 340.108 driver for G92 that patched for 6.8 kernel without dkms
yay -S nvidia-340xx
all booting good, but Artix use mesa instead blob nvidia?
nouveau blacklisted at modeprobe and gub
llvmpipe is software renderer, so it looks like nvidia is not working properly.
Try to check dmesg and Xorg logs for more information.
If you are under Wayland, than good luck and return to X, old nvidia drivers do not support it well.
add this section to /etc/X11/xorg.conf.d/20-nvidia.conf
