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'

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
