Linux的lspci命令可以列出目前主机上面的硬件配备，vga则表示显卡。
列出显卡信息如下：
$ lspci | grep -i vga
02:00.0 VGA compatible controller: NVIDIA Corporation GP102 [TITAN Xp] (rev a1)
03:00.0 VGA compatible controller: NVIDIA Corporation GP102 [TITAN Xp] (rev a1)
06:00.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 30)
83:00.0 VGA compatible controller: NVIDIA Corporation GP102 [TITAN Xp] (rev a1)
其中，每一行开头为每一个硬件设备的序号，如02:00.0，03:00.0等。
通过序号查看显卡的详细信息：
lspci通过-s指定序号，如示例里的02:00.0
$ lspci -v -s 02:00.0
