I have a Lenovo Legion Y530 with an Intel integrated graphics processor along with an Nvidia 1050Ti. I’m trying to configure the system to work with my graphics card, in particular, Blender. I’ve already discovered the cudaSupport flag and enabled it, and, curiously, this actually succeeded until I rebooted. Now, the GPU is once again not working. I’m following the instructions at Nvidia - NixOS Wiki, and running nvidia-offload on Blender & Firefox gives errors:

Error! Unsupported graphics card or driver.
A graphics card and driver with support for OpenGL 3.3 or higher is required.
The program will now close.

I’m at a complete loss as to what could be causing this. I’ve searched far & wide, and I’ve tried many things, such as modesetting, Optimus-less mode (my card seems to be output-producing), etc…
I’m on the unstable channel (though it also does not work on the NixOS 21.05 channel).
