[SOLVED] NVIDIA Optimus - using llvmpipe instead of NVIDIA
Up until yesterday, I had the configuration from the wiki to always use my NVIDIA GPU. Then, I must have changed something, because I noticed very poor performance in Minecraft, which showed no GPU at all was being used. Instead, llvmpipe was used as software renderer. I do not wish that.
I tried going for other solutions, such as using prime-run. The problem with this is that the flight simulator X-Plane 11 crashes with vulkan drivers enabled when launching with prime-run. What I want is to always use the NVIDIA GPU.
Now for some info.
$ nvidia-smi

I checked other posts and followed the steps they did, but it did not work.
What am I missing?
Edit: As a side note, this post might be better suited for the hardware section, but these errors make me think that the NVIDIA GPU isn't directly wired to the screen, because when I delete the intel driver from 10-nvidia-drm-outputclass.conf, I get a black screen when starting X (with startx), so it might be a laptop-related issue.

Re: [SOLVED] NVIDIA Optimus - using llvmpipe instead of NVIDIA
Thank you, that immediately fixed it!
Why isn't this information in the news on the main page?
