'Couldn't find matching GLX visual
I'm struggling to initialise an OpenGL display using pygame and pyopengl.
import pygame
pygame.init()
pygame.display.set_mode((1920, 1080), pygame.OPENGL)
gives the error:
pygame.error: Couldn't find matching GLX visual
If I don't specify pygame.OPENGL I get a properly initialised display and a pygame window.
- I'm using python 3 (
Python 3.6.2 :: Anaconda custom (64-bit)) - I'm on Manjaro Linux, running
i3windows manager - I'm on a Dell XPS laptop, which has both Intel and Nvidia graphics adapters and I'm using
optirunto use the Nvidia hardware, but I get the same effect regardless of which graphics adapter I use glxgearsandoptirun glxgearsboth work fine, so I believe that OpenGL is available on the machine and working fineoptirun glxinfohttps://pastebin.com/v6VjZgBZ
In an attempt to find a suitable set of display parameters, I ran:
import pygame
from pygame.locals import *
pygame.init()
print(pygame.display.Info())
print(pygame.display.list_modes(32, pygame.FULLSCREEN))
print(pygame.display.mode_ok((1920, 1080)))
print(pygame.display.mode_ok((1920, 1080), pygame.OPENGL))
Which gave the following output:

blit_hw = 0, blit_hw_CC = 0, blit_hw_A = 0,
blit_sw = 0, blit_sw_CC = 0, blit_sw_A = 0,
bitsize = 32, bytesize = 4,
masks = (16711680, 65280, 255, 0),

Please help me to diagnose the problem and get an OpenGL enabled pygame window going.
Update 20190131
I tried in ipython (python 3.6.2) setting 24-bit colour mode as suggested by @hidefromkgb, but I got the same issue (I had tried this before):
In [1]: import pygame
In [2]: pygame.init()
Out[2]: (6, 0)
In [3]: pygame.display.set_mode((1920, 1080), pygame.OPENGL, 24)

error: Couldn't find matching GLX visual
I am able to get OpenGL working from c++ using GLUT without problems.
Update #2 20190131
I have two minimal programs now (python, c++) with accompanying strace output (see https://paste.ee/p/ah1nq).
This python program fails with the GLX Visuals error:
import pygame
pygame.init()
pygame.display.set_mode((1920, 1080), pygame.OPENGL)
This c++ programs succeeds in creating a window:
#include <GL/glut.h>
void display(void) {
}
int
main(int argc, char **argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH);
glutCreateWindow("window initialisation test");
return 0;
}
The c++ program was compiled with g++ test.cpp -lGL -lglut -o test.
I had a look at the strace output, but couldn't make heads nor tails of it.
Update #3 20190131
I ran ltrace on the two above programs and got

Thanks for the input, @hidefromkgb.
I tried using pygame.OPENGL | pygame.DOUBLEBUF and also just passing 18, but got the same result.
import pygame
from pygame.locals import *
pygame.init()
pygame.display.set_mode((1920, 1080), pygame.OPENGL | pygame.DOUBLEBUF)

Solution 1:[1]
Sorry for the late answer, haven`t seen your edit before. In the future, please call people by nicknames in comments if you need to have their attention.
ltrace seems to have made the issue clearer. The first parameter to glutInitDisplayMode equals 18 which means GLUT_DOUBLE | GLUT_DEPTH, for GLUT_DOUBLE = 2, GLUT_DEPTH = 16.
In its turn, pygame.display.set_mode call lacks both of these flags during GL initialization.
Try using pygame.OPENGL | pygame.DOUBLEBUF instead of just the pygame.OPENGL.
