I'm trying very hard to set up hybrid graphics on my Lenovo P52 with a Quadro P1000 (HDMI is wired directly to the graphics card as far as I read); I got it running once (Kernel 4.14, nvdia hybrid graphics driver 390xx bumblebee, but with Askannz' optimus-manager as far as I remember) but had no reason to use it a lot. Now, I got the necessity to use my GPU for an external Display and later for CUDA as well, so I realized, after updating Manjaro to version 20 and graphics driver to
video-hybrid-intel-nvidia-440xx-prime that I am not able to use my GPU anymore. The problem seems to be that, no matter what I do, graphics driver with
inxi -G````stays N/A```. I tried quite hard for days to get my setup working, so did i follow (or only read, if they are outdated) different tutorials, as
Guide: Install and configure optimus-manager for hybrid GPU setups or [HowTo] Set up PRIME with NVIDIA proprietary driver and another one which I cannot find anymore at the moment, showing all the oportunities for the hybrid setup, as only PRIME and optimus to mention. I tried different combinations of kernels and drivers to preclude any compatibility-issues, as: Kernels 4.14, 4.19, 5.5 and 5.6 with the drivers 390xx, 435xx and 440xx, always the hybrid-versions and every combination of each. Driver stays n/a, and
nvidia-setting not being able to load or communicate with the nvidia-driver.
I am aware that there might be some issue with gdm (-prime) or some config-files I missed (in directories
/etc/X11/xorg.config.d/but I can't see the forest for the trees at the moment.
After reboots i mainly get stuck in a black screen and have to reinstall the former drivers via tty to be able to start to graphics mode again.
My head is stuck but I want to and need to get this working. If I missed something, just advice me, any help is appreciated. I know that there are a lot of similar-reading issues in the forum and I think I read the most of them but nothing could help me.
Thank you very much in advance for your help.
