命令行查看GPU信息

使用lspci

Peripheral Component Interconnect(PCI) 提供了协议来查询外设信息，当然也包括显卡信息了。

在PCI ID仓库 中记录了所有已知PCI ID对应的外设

在Linux上可以使用lspci命令来查看PCI设备的信息 

lspci -v |sed -n '/VGA\|3D/,/^$/p'

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) (prog-if 00 [VGA controller])

        Subsystem: Lenovo NVS 5200M
        Flags: bus master, fast devsel, latency 0, IRQ 36
        Memory at f0000000 (32-bit, non-prefetchable) [size=16M]
        Memory at c0000000 (64-bit, prefetchable) [size=256M]
        Memory at d0000000 (64-bit, prefetchable) [size=32M]
        I/O ports at 5000 [size=128]
        Expansion ROM at <ignored> [disabled]
        Capabilities: <access denied>
        Kernel driver in use: nouveau
        Kernel modules: nouveau

如果没有结果，那可能需要更新一下本地的PCI数据库备份，运行下面命令进行更新 

sudo update-pciids

使用lshw

lshw会显示所有硬件设备的信息，而不仅仅是PCI设备的信息

lshw将硬件分成很多类别，我们可以使用 -C 选项指定要显示的设备类型: 

lshw -C display
