I also don't know if it would affect it, but I have a Cintiq 13 attached. I've added photos of what is popping up, and my computer specs. I've tried installing an older version (the version I was working on before, and that doesn't work either. I've found an opengl32.dll file and moved it into the blender folder, and it opened the program, but ran terribly slow (very glitchy and would eventually not respond when I click different shading views), I uninstalled it and reinstalled it and now adding that file doesn't even let it open. Upload an image of GPU-Z and at the bottom where it checks all the APIs that are enabled see if OpenGL is showing version 1.1. This seems to be a bug either in Windows itself or AMD driver.
Another alternative could be to use mesa utils: sudo apt install mesa-utils glxinfo -B. To check for the currently used graphics driver execute: sudo lshw -c video. I've tried updating my graphics card drivers (they're up to date), I've uninstalled and reinstalled them just to be sure. Most likely your GPU card OpenGL is showing version 1.1 if you run GPU-Z. Graphics driver check Ubuntu 20.04 Focal Fossa step by step instructions. The last time I used it was in December of 2020, so I know it's updated, but I'm pretty sure my computer specs should be good enough to run the program.
I've recently wanted to get back into using blender for some fun art projects, but anytime I try and install the program and run it, I run into issues.
