So I had to update the nvidia drivers from 440xx to 450xx, as otherwise pacman -Syu wouldn’t run. I’ve removed all packages related to 440xx and installed 450xx, and used mhwd -r to remove the old video-hybrid-intel-nvidia-440xx-prime and then installed video-hybrid-intel-nvidia-450xx-prime. Doing mhwd -li shows this driver is installed. However, inxi -G says this about the nvidia device:
Device-2: NVIDIA GM107M [GeForce GTX 960M] driver: N/A
In light of that, it is probably not surprising that nvidia-smi says “NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running”.
My question is, what am I missing? Why isn’t the driver being loaded?
