I am running Fedora 31 on an HP Envy 17t laptop with a NVIDIA MX250 gpu.
I have installed the NVIDIA driver downloaded from NVIDA, and it seems
to have installed just fine. I have installed CUDA, as far as I can tell.
I am trying to use the GPU rendering capabilities of Blender, a 3D
modeling package. However, the package does not believe there is a CUDA
compatible GPU installed.
I *think* it's because I'm actually running the Intel VGA controller.
So, if I'm right, my question is, how do I disable the Intel VGA
controller (or not make it the default) so it uses the NVIDIA controller.
Depending on how the hardware is setup, you might not be able to disable
the Intel one. (See the other very long thread here that has been
discussing that same issue for an AMD setup.) Do you have a right-click
option to run applications on the other GPU?
First, of course, graphics seems to work in general. Blender runs fine,
but (for those of you who might use blender), when using the Cycles
renderer, I can only render using the CPU.

The driver is loaded.
The following is a little odd. This used to load, but while floundering
about, I removed and reinstalled the Nvidia driver from NVIDIA. Now it
won't load:
$ nvidia-settings
ERROR: Unable to load info from any available system
This is a problem. If the settings app can't find the card, then CUDA
likely won't be able to either. You probably have to fully clean out
all the NVidia stuff and reinstall it properly.
I assume the tainting stuff below is because I'm using the driver
downloaded from NVIDIA.
Yes.
You downloaded it from NVidia instead of using the rpmfusion packages?
Cleaning it up will be extra fun then...
