這裡介紹幾種在 Linux 系統上使用指令查詢 Nvidia 驅動程式版本以及 GPU 顯示卡資訊的方法。
nvidia-smi 指令工具
Nvidia 所提供的 nvidia-smi（NVIDIA System Management Interface）管理工具可以直接查詢驅動程式與顯示卡的資訊：

Linux 系統指令
除了使用 Nvidia 所提供的工具之外，也可以從 kernel 組入的驅動程式來看：
cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86_64 Kernel Module 375.26 Thu Dec 8 18:36:43 PST 2016 GCC version: gcc version 4.8.5 20150623 (Red Hat 4.8.5-4) (GCC)
或是使用 modinfo 查看：
