I am trying to figure out which version of OpenGL my graphics card and driver currently support. This answer suggests running glxinfo | grep OpenGL which if fine, but here is (some) of that output: So it is hard to tell, is it 4.5 or 4.6? Also the official documentation from nVidia does not mention the answer either! Answer That

Is there a way to automatically link all libraries an OpenGL program needs, without explicitly writing their flags on compile?
For an entry level program, I’m currently compiling with g++ manip.c -o manip -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -ldl -lXinerama -lXcursor -lGLEW It was a very time-consuming process of trial and error figuring out which flags were necessary, googling the ‘undefined references to’, copy pasting every flag I came across and then deleting flags one by one until I had
Error: ‘GL/glfw3.h: No such file or directory’ when compiling C++ programs using OpenGL on Linux
I receive the error message when I try to compile the example program given in the tutorial here, section ‘Opening a window’. I have installed all the libraries they referred to in the ‘Building on Linux’ section. (My distribution is Ubuntu 16.04.) I have also successfully run as I found suggested somewhere as an answer to this issue. I think
Installing VTK: matching usr/lib/libGL.so path to the one in build system config
I’ve been trying to install VTK on my Ubuntu 14.04. I had some trouble getting things to configure since it couldn’t find OpenGL, but I (thought I) fixed that by using and as was suggested in this question. However, now I can’t run make because the path to libGL.so isn’t correct. I’ve been searching and finding all sorts of strange
Disable OpenGL for Python / Matplotlib
I’m doing a Python course for which I have installed Arch Linux in a VM. When I use Matplotlib.pyplot to plot things (x vs y) I get a bunch of errors. When I turn of 3D support for the VM it simply asks for openGL. My script does create a plot (empty canvas) but without a line. I think it
OpenGL full screen texture brings framerate down to 12fps
I installed linux (Debian) on an old laptop and have been writing an OpenGL application with it. The framerate cruises at about 80fps when drawing a texture on a small portion of the screen. When I draw the texture on a bigger and bigger portion of the screen, the framerate drastically drops. A full-screen texture drops the fps to 12.
