opengl/glx 코어 덤프 - 범용 Intel Linux 드라이버, RHEL6

최근 ATI 카드가 손상되어 X 서버에서 완벽하게 작동하는 독점 드라이버를 얻을 수 없었기 때문에 전용 ATI 카드 및 독점 드라이버 사용에서 온보드 Intel 그래픽 및 기본/일반 Intel 드라이버 사용으로 전환했습니다.

어쨌든 이제 OpenGL을 사용하는 프로그램이 실행될 때마다 코어 덤프가 생성됩니다. 예를 들어:

[birdsnest ~]% glxinfo -v  
name of display: :0
zsh: segmentation fault (core dumped)  glxinfo -v

편집: 코어 덤프에서 역추적(이것이 얼마나 유용한지, 어떻게 활용하는지 모르겠습니다):

그래서 이것이 드라이버 문제인지 아니면 다른 문제인지 잘 모르겠고, 디버깅하는 방법도 모르겠습니다. 이 문제를 어떻게 디버깅해야 하는지 아는 사람이 있나요?

Module glx: vendor="Advanced Micro Devices, Inc."편집: 방금 xorg 로그에서 이 줄을 발견했습니다. 파일이 아주 최근에 마지막으로 수정되었다는 것을 알았습니다. ATI 비디오 드라이버를 설치할 무렵이었습니다. 독점 ATI 드라이버를 설치할 때 이 라이브러리가 손상될 가능성이 있습니까?
