检查Xorg X服务器日志

找到nvidia驱动程序版本的另一个方法是查看 Xorg X服务器日志文件：

# grep "X Driver" /var/log/Xorg.0.log
[    10.295] (II) NVIDIA dlloader X Driver  352.63  Sat Nov  7 20:29:25 PST 2014

使用 NVIDIA-SMI实用程序以显示NVIDIA驱动程序版本：

# nvidia-smi 
Fri Dec 25 16:49:12 2014       
+------------------------------------------------------+                       
| NVIDIA-SMI 352.63     Driver Version: 352.63         |                       
|-------------------------------+----------------------+

检索模块版本

下面的命令将在当前运行的内核下检查NVIDIA驱动程序版本：

# modinfo /usr/lib/modules/$(uname -r)/kernel/drivers/video/nvidia.ko | grep ^version
version:        352.63

即使未加载NVIDIA模块，上述情况也适用。
运行以下命令以找到nvidia.ko模块文件的位置：

# find /usr/lib/modules -name nvidia.ko

或者，在Find命令返回的所有结果上运行modInfo命令：

# find /usr/lib/modules -name nvidia.ko -exec modinfo {} \;
