How to configure Nvidia driver after driver installation

I am running fedora 30 on a laptop which has an 840M Graphics card. I have installed the Nvidia proprietary drivers using the RPM fusion method. The drivers are usable if I use the __NV_PRIME_RENDER_OFFLOAD=1 environment variable while launching an app. However, there are still a couple of problems. Firstly, when I try to run `LIBVA_LIBRARY_NAME=nvidia vainfo` I get the following error: Maximum number of clients reached libva error: /usr/lib64/dri/nvidia_drv_video.so init failed Secondly, the Nvidia Xserver settings dialog does not show any X server settings also the application profiles section is also not usable. It also throws this error when run from command line nvidia-settings:10481): GLib-GObject-CRITICAL **: 23:52:57.685: g_object_unref: assertion 'G_IS_OBJECT (object)' failed ERROR: nvidia-settings could not find the registry key file. This file should have been installed along with this driver at /usr/share/nvidia/nvidia-application-profiles-key-documentation What next steps should I take to get this running properly?
