Question

当我尝试执行程序时出现此错误：

libGL error: unable to load driver: i965_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: i965
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast
X Error of failed request:  GLXBadFBConfig
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  34 ()
  Serial number of failed request:  42
  Current serial number in output stream:  41

我的代码（我从“OpenGL开发手册”一书中摘录）：

#include <GL/glew.h>
#include <GL/freeglut.h>
#include <iostream>

const int WIDTH = 640;
const int HEIGHT = 480;

void OnInit()
{
   glClearColor(1, 0, 0, 0);
   std::cout << "Initialization successfull" << std::endl;
}

void OnShutdown()
{
   std::cout << "Shutdown successfull" << std::endl;
}

void OnResize(int nw, int nh)
{

}

void OnRender()
{
   glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
   glutSwapBuffers();
}

int main(int argc, char** argv)
{
   glutInit(&argc, argv);
   glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);
   glutInitContextVersion(3, 3);
   glutInitContextFlags(GLUT_CORE_PROFILE | GLUT_DEBUG);
   glutInitContextProfile(GLUT_FORWARD_COMPATIBLE);
   glutInitWindowSize(WIDTH, HEIGHT);
   glutCreateWindow("OpenGL");

   glewExperimental = GL_TRUE;
   GLenum err = glewInit();

   if(GLEW_OK != err) {std::cerr << "Error: " << glewGetErrorString(err) << std::endl; }
   else{if(GLEW_VERSION_3_3) {std::cout << "Driver supports OpenGL 3.3\n Details: " << std::endl; }}

   std::cout << "\tUsing glew: " << glewGetString(GLEW_VERSION) << std::endl;
   std::cout << "\tVendor: " << glGetString(GL_VENDOR) << std::endl;
   std::cout << "\tRenderer: " << glGetString(GL_RENDERER) << std::endl;
   std::cout << "\tGLSL: " << glGetString(GL_SHADING_LANGUAGE_VERSION) << std::endl;

   OnInit();
   glutCloseFunc(OnShutdown);
   glutDisplayFunc(OnRender);
   glutReshapeFunc(OnResize);
   glutMainLoop();
   return 0;
}

我验证了我的驱动程序是否支持我使用的 glxinfo |的OpenGL版本grep“OpenGL”命令：

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile 
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.5.9
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 10.5.9
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:

我正在使用 Ubuntu 14.04.3 。

我不确定，但我认为我收到此错误是因为我使用的是英特尔，而不是 Nvidia 。

Answer 1

从远处看很难说，但是你在那里遇到的错误看起来像是一个损坏的OpenGL客户端库安装。 glxinfo查询加载到Xorg服务器的GLX驱动程序，它与安装的libGL有些独立（只要进行间接渲染调用）。错误表明安装的libGL与DRI驱动程序不匹配或DRI库已损坏。

无论哪种方式，最好的方法是在系统上彻底重新安装与OpenGL相关的所有内容。即强制重新安装xorg-server，xf86-video- ...，mesa，libdri ......等等。

我遇到了一个非常类似的错误：

X Error of failed request:  GLXBadFBConfig
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  34 ()
  Serial number of failed request:  42
  Current serial number in output stream:  41

删除以下行解决了它：

glutInitContextVersion(3, 3);
