最近，我从使用专用 ATI 显卡和专有驱动程序切换到板载 Intel 显卡和默认/通用 Intel 驱动程序，因为 ATI 显卡已损坏，并且我无法让专有驱动程序与我的 X 服务器完美配合。
不管怎样，现在每当使用 OpenGL 的程序运行时我都会得到核心转储。例如：

编辑：从核心转储回溯（我不知道这有多大用处或如何利用它）：

所以我不确定这是驱动程序问题还是其他问题，而且我不知道如何调试。有人知道我应该如何调试这个问题吗？
Module glx: vendor="Advanced Micro Devices, Inc."编辑：我刚刚注意到我的 xorg 日志中的这一行。我注意到该文件的上次修改时间相当近期 - 大约是我安装 ATI 视频驱动程序的时间。当我安装专有的 ATI 驱动程序时，该库是否可能被破坏？
答案1
我想到了。正如我怀疑的那样，AMD想要使用的共享库与Intel驱动程序使用的共享库之间存在冲突。解决办法是卸载AMD驱动。我通过运行卸载脚本来做到这一点/usr/share/ati。运行此脚本后，我必须恢复我/etc/X11/xorg.conf一直在使用英特尔驱动程序的脚本，因为卸载脚本试图破坏它。
