Hi there.
I have a laptop with dual graphics: intergrated AMD + Nvidia. After Unreal engine started crashing with a vukan_amd.so
in the callstack, I started researching which gpu it’s actually using. None of the tools I tried prove that Nvidia is utilized. I tried nvtop
(shows only AMD), nvidia-smi
(returns an error of missing driver), xrandr --listproviders
(only AMD).
I went on to reinstall the drivers. Cleaned the old one and let mhwd
do it automatically. I got the driver, pacman nvidia packages. But nvidia-smi
still fails. nvidia-settings
does not have any configuration options that should be there.
Help me configure this properly please! I tried following this and this manuals.
Here’s the output of some commands:
$ nvidia-smi 9 ✘
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
$ nvidia-settings ✔
ERROR: NVIDIA driver is not loaded

ERROR: nvidia-settings could not find the registry key file or the X server is not accessible. This file should have been installed along with this driver at
/usr/share/nvidia/nvidia-application-profiles-key-documentation. The application profiles will continue to work, but values cannot be prepopulated or validated, and will not be
listed in the help text. Please see the README for possible values and descriptions.
