I installed nvidia in ubuntu 16.04, currently the os uses GPU graphcis (which I checked in system settings>details)

However, I would like to confirm about nvidia opengl library is working or not? after run glxinfo | grep OpenGL it gives:

OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce RTX 2080 Ti/PCIe/SSE2 OpenGL core profile version string:
4.5.0 NVIDIA 418.39 OpenGL core profile shading language version string: 4.50 NVIDIA OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 4.6.0 NVIDIA 418.39 OpenGL shading language version string: 4.60 NVIDIA OpenGL context flags: (none) OpenGL profile mask: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 418.39 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20 OpenGL ES profile extensions:

Is it OK? Is there any suggestion please?

  • Libraries are usually not something that works. Instead, they are used by other programs. What makes you think an opengl lib not ising working?

  • @mikewhatever Thanks for your comment. Yes, I agree with you. 1. I want to check the library is installed successfully or not? 2. So I need to use some example to run with nvidia opengl library

  • Run glxinfo | grep OpenGL

  • This is all very vague indeed. 1. Opengl is preinstalled, and you can run dpkg -l | grep libgl to verify. 2. Since you insist to run something, they benchmark tools askubuntu.com/questions/31913/….
