python - 找不到匹配的 GLX 视觉

我正在努力使用 pygame 初始化 OpenGL 显示。和pyopengl .

import pygame
pygame.init()
pygame.display.set_mode((1920, 1080), pygame.OPENGL)

给出错误:

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 i3 windows manager
  • I'm on a Dell XPS laptop, which has both Intel and Nvidia graphics adapters and I'm using optirun to use the Nvidia hardware, but I get the same effect regardless of which graphics adapter I use
  • glxgears and optirun glxgears both work fine, so I believe that OpenGL is available on the machine and working fine
  • optirun glxinfo https://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))

输出如下:

VideoInfo(hw = 0, wm = 1,video_mem = 0
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),
shifts = (16, 8, 0, 0),
losses = (0, 0, 0, 8),
current_w = 3200, current_h = 1800

[(3200, 1800), (2880, 1620), (2560, 1600), (2560, 1440), (2048, 1536), (2048, 1152), (1920, 1440), (1920, 1200), (1920, 1080), (1856, 1392), (1792, 1344), (1680, 1050), (1600, 1200), (1600, 900), (1400, 1050), (1400, 900), (1368, 768), (1280, 1024), (1280, 960), (1280, 800), (1280, 720), (1024, 768), (1024, 576), (960, 540), (864, 486), (800, 600), (720, 405), (640, 480), (640, 360)]

以下是 optirun glxinfo 的摘录,即glxinfo对于 Nvidia 适配器,显示了几个 GLX 视觉效果(完整输出 https://pastebin.com/v6VjZgBZ ):

请帮助我诊断问题并让启用 OpenGL 的 pygame 窗口运行。

更新20190131我试过ipython (python 3.6.2)按照@hidefromkgb的建议设置24位颜色模式,但我遇到了同样的问题(我之前尝试过):

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

我能够使用 GLUT 从 C++ 中让 OpenGL 正常工作,没有任何问题。

更新 #2 20190131

我现在有两个最小的程序( pythonc++ )以及附带的 strace 输出(请参阅 https://paste.ee/p/ah1nq )。

这个python程序失败并出现 GLX Visuals 错误:

import pygame
pygame.init()
pygame.display.set_mode((1920, 1080), pygame.OPENGL)

这个c++程序成功创建窗口:

#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;
}

c++程序是用 g++ test.cpp -lGL -lglut -o test 编译的.

我查看了 strace输出,但无法弄清楚它的正反面。

更新 #3 20190131

我跑了ltrace对以上两个程序进行分析,得到

感谢您的意见,@hidefromkgb。

我尝试使用pygame.OPENGL | pygame.DOUBLEBUF也只是路过 18 ,但得到了相同的结果。

import pygame
from pygame.locals import *

pygame.init()
pygame.display.set_mode((1920, 1080), pygame.OPENGL | pygame.DOUBLEBUF)

最佳答案

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似乎已经把问题说得更清楚了。第一个参数为glutInitDisplayMode等于 18,这意味着 GLUT_DOUBLE | GLUT_DEPTH ,对于GLUT_DOUBLE = 2, GLUT_DEPTH = 16。

反过来,pygame.display.set_mode GL 初始化期间调用缺少这两个标志。

尝试使用pygame.OPENGL | pygame.DOUBLEBUF而不仅仅是 pygame.OPENGL .
