I have tested installing nvidia driver in many ways. When I input nvidia-settings and access to the NVIDIA settings X server, I cannot see the prime profile, which means I can't switch the GPU. When I input prime-select query, the output is nvidia Device 3881ģe:00.0 VGA compatible controller: NVIDIA Corporation Device 2204 (rev a1)Ĩ9:00.0 VGA compatible controller: NVIDIA Corporation Device 2204 (rev a1)ī1:00.0 VGA compatible controller: NVIDIA Corporation Device 2204 (rev a1) Subsystem: Micro-Star International Co., Ltd. ASPEED Graphics Familyġa:00.0 VGA compatible controller: NVIDIA Corporation Device 2204 (rev a1) The output is listed following: 03:00.0 VGA compatible controller: ASPEED Technology, Inc. When I input lspci -k | grep -A 2 -i "VGA", I don't know whether this is right. | 3 N/A N/A 2318 G /usr/lib/xorg/Xorg 4MiB | | 2 N/A N/A 2318 G /usr/lib/xorg/Xorg 4MiB | | 1 N/A N/A 2318 G /usr/lib/xorg/Xorg 4MiB | | 0 N/A N/A 2318 G /usr/lib/xorg/Xorg 4MiB |

OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10Īlso, I can get some information from the GUI, settings->detials->Graphics: llvmpipe(LLVM 10.0.0, 256 bits). OpenGL ES profile version string: OpenGL ES 3.1 Mesa 20.0.8 OpenGL shading language version string: 1.40 OpenGL core profile profile mask: core profile OpenGL core profile context flags: (none) OpenGL core profile shading language version string: 3.30 OpenGL core profile version string: 3.3 (Core Profile) Mesa 20.0.8 To check the OpenGL Version, sudo glxinfo | grep OpenGL, following is the Output: OpenGL renderer string: llvmpipe (LLVM 10.0.0, 256 bits) I'm sorry to ask such a question, but I am bothered by this question for more than two weeks.Īll the information is from the GPU server, (4 NVIDIA 3090 GPUs).
