本文介绍了如何在Linux操作系统中查询VGA和NVIDIA显卡设备的相关信息，包括基本步骤和相关命令，帮助用户了解自己的计算机硬件配置。

查看VGA设备

$ lspci | grep -i vga
08:00.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 30)
(test_env) 

$ lspci -v -s 08:00.0     
08:00.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 30) (prog-if 00 [VGA controller])
	Subsystem: ASPEED Technology, Inc. ASPEED Graphics Family
	Flags: bus master, medium devsel, latency 0, IRQ 16, NUMA node 0
	Memory at c6000000 (32-bit, non-prefetchable) [size=16M]
	Memory at c7000000 (32-bit, non-prefetchable) [size=128K]
	I/O ports at 5000 [size=128]
	Expansion ROM at <unassigned> [disabled]
	Capabilities: <access denied>
	Kernel driver in use: ast
