X Error of failed request: BadValue (integer parameter out of range for operation), PyOpenGL

Question

I have this code:

import pygame

from pygame.locals import *
from OpenGL.GL import *
from OpenGL.GLU import *


vertices= (
    (1, -1, -1),
    (1, 1, -1),
    (-1, 1, -1),
    (-1, -1, -1),
    (1, -1, 1),
    (1, 1, 1),
    (-1, -1, 1),
    (-1, 1, 1)
    )

edges = ((0,1),(0,3),(0,4),(2,1),(2,3),(2,7),(6,3),(6,4),(6,7),(5,1),(5,4),(5,7))

surfaces = (
(0,1,2,3),
(3,2,7,6),
(6,7,5,4),
(4,5,1,0),
(1,5,7,2),
(4,0,3,6)
)


def Cube():

  glBegin(GL_QUADS)
  for surface in surfaces:
      x = 0
      for vertex in surface:
          x+=1
          glColor3fv(colors[x])
          glVertex3fv(verticies[vertex])
  glEnd()

  glBegin(GL_LINES)
  for edge in edges:
      for vertex in edge:
          glVertex3fv(verticies[vertex])
  glEnd()



def main():

  pygame.init()
  display = (800,600)
  pygame.display.set_mode(display, DOUBLEBUF|OPENGL)

  gluPerspective(45, (display[0]/display[1]), 0.1, 50.0)

  glTranslatef(0.0,0.0, -5)

  while True:

      for event in pygame.event.get():
          if event.type == pygame.QUIT:
              pygame.quit()
              quit()

      glRotatef(1, 3, 1, 1)
      glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT)
      Cube()
      pygame.display.flip()
      pygame.time.wait(10)



if __name__ == "__main__":

   main()

and this error:

 X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 154 (GLX) Minor opcode of failed request: 3 (X_GLXCreateContext) Value in failed request: 0x0 Serial number of failed request: 25 Current serial number in output stream: 26

I think these three lines have problem, actually line three, display mode:

pygame.init()
display = (800,600)
pygame.display.set_mode(display, DOUBLEBUF|OPENGL)

Only with this part of code in main function, I have the same problem. If I comment third line in main function I get, of course, error:

Traceback (most recent call last): File "cube_0.py", line 66, in main() File "cube_0.py", line 60, in main pygame.display.flip() pygame.error: Display mode not set

Answer 1

See Pygame OpenGL init causes an X Error . The issue has nothing to do with your code. It is causes by your system or graphics driver. Possibly you have to update pygame.

Answer 2

On Ubuntu 20.04 (uses bash), pygame.init() was giving me the above X Error. Putting the following in my ~/.bashrc solved it for me:

export SDL_VIDEODRIVER='dummy'

Note, also that my $DISPLAY environment variable is :0 One may thus also need the following in ~/.bashrc .

export DISPLAY=:0

I was also running code from Pycharm, which required me to start pycharm.sh from a terminal session that already had the above environment variables initialized (it's a bug in Pycharm 2021).
