我在使用 Nvidia GeForce 9100 的 nouveau 驅動程式時遇到問題/var/log/Xorg.0.log。
$ 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
當我從 shell 運行 glxinfo 或 glxgears 時，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 顯示驅動程式已載入
$ dmesg | grep nouveau

我多次安裝和刪除了 Nvidia 專有驅動程序，因此庫和其他內容可能有問題。在我看來，系統正在尋找，/usr/lib64/dri/nouveau_dri.so而它不應該尋找。據我所知，沒有 CentOS 6 軟體包提供該文件。
任何幫助將不勝感激，提前謝謝您。
