1、使用lspci查看顯卡PCI設(shè)備

root@jiangyu-HP:~# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Device 3e9b
01:00.0 VGA compatible controller: NVIDIA Corporation GP107M [GeForce GTX 1050 Mobile] (rev a1)

2、再使用lspci命令查看詳細(xì)的顯卡型號(hào)，可以查看該設(shè)備的制造商、產(chǎn)品代碼和其他信息，以確定它是否為獨(dú)立顯卡。

在上述情況下，01:00.0顯卡是獨(dú)立顯卡，因?yàn)樗怯?NVIDIA Corporation生產(chǎn)的。相反，00:02.0顯卡是由Intel Corporation生產(chǎn)的，通常是內(nèi)置顯卡。
