我在使用 Nvidia GeForce 9100 的 nouveau 驱动程序时遇到了问题。Xorg 启动并运行正常，我可以使用一切，尽管/var/log/Xorg.0.log我有：
$ cat /var/log/Xorg.0.log | grep EE
[ 36.166] (EE) AIGLX error: dlopen of /usr/lib64/dri/nouveau_dri.so failed (/usr/lib64/dri/nouveau_dri.so: cannot open shared object file: No such file or directory)
[ 36.166] (EE) AIGLX: reverting to software rendering
当我从 shell 运行 glxinfo 或 glxgears 时，我得到
libGL error: dlopen /usr/lib64/dri/nouveau_dri.so failed (/usr/lib64/dri/nouveau_dri.so: cannot open shared object file: No such file or directory)
libGL error: unable to load driver: nouveau_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: nouveau
但 dmesg 显示驱动程序已加载

我多次安装和删除了 Nvidia 专有驱动程序，因此库和其他东西可能存在问题。在我看来，系统似乎/usr/lib64/dri/nouveau_dri.so在寻找它不应该寻找的东西。据我所知，没有 CentOS 6 软件包提供该文件。
如能得到任何帮助我将非常感激，提前谢谢您。
