I was wondering how can I set my system up so that I can use my nvidia dgpu on difficult tasks and amd igpu for simple tasks. I have managed to make it work on Manjaro, using prime-run, but I can't figure it out on Ubuntu, as I am require to use Ubuntu.
CPU: AMD Ryzen 7: 4800HS GPU: Nvidia GeForce RTX 2060 with Max-Q
lspci | grep VGA output:
01:00.0 VGA compatible controller: NVIDIA Corporation TU106 [GeForce RTX 2060] (rev a1) 05:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Renoir (rev c6)
As far as I know, the best option is prime render offload, but what are the steps to make it work on a fresh Ubuntu 20.04 system? I would really appreciate a step-by-step answer.
lspci -k | grep -EA3 'VGA|3D|Display' output:
01:00.0 VGA compatible controller: NVIDIA Corporation TU106 [GeForce RTX 2060] (rev a1) Subsystem: ASUSTeK Computer Inc. Device 1e11 Kernel driver in use: nvidia Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia -- 05:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

I am wondering because glxinfo | grep OpenGL gives:
OpenGL vendor string: VMware, Inc. OpenGL renderer string: llvmpipe (LLVM 9.0.1, 128 bits) OpenGL core profile version string: 3.3 (Core Profile) Mesa 20.0.4 OpenGL core profile shading language version string: 3.30 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.1 Mesa 20.0.4 OpenGL shading language version string: 1.40 OpenGL context flags: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.1 Mesa 20.0.4 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10
So there is nothings about nvidia.
I have tried different solutions for a week already and nothing worked for me when I used Ubuntu.
I can provide any other information if required.
Thanks in advance!
