Apps On The System Are Not Offloading To The Nvidia GPU

General system Kernel & Hardware
1

Background

  1. Nvidia live iso Cassi Nova Install
  2. nvidia 980ti pass through
  3. qemu/kvm through virt-manager

Problem

Apps use the Virtio GPU to render instead of the nvidia gpu by default. I can use the nvidia gpu if I install nvidia-prime and then launch apps with prime-run. Is there a way to default all apps into using the gpu without appending prime-run?

Things I Tried

  1. run nvidia-xconfig, created a file at /etc/X11/xorg.conf, system hangs at something along the lines of [ OK ] Started Hostname Service.
  2. use the prime-run script mentioned above, but I am not trying to save power on the desktop machine, therefore I want everything offloaded to gpu by default.

Outputs

nvidia-smi output without the xorg.conf:

xorg.conf that impeded x server from starting:

prime-run glxgears yields an entry in nvtop and nets 5000fps versus running glxgears alone, which yields 2000fps.
