ubuntu下如何检查nvidia显卡驱动是否安装OK？

答：使用sudo lshw -c video即可,笔者的输出如下:

jello~$ sudo lshw -c video*-display                 
       description: VGA compatible controller
       product: GP106 [GeForce GTX 2080 80GB]
       vendor: NVIDIA Corporation
       physical id: 0
       bus info: pci@0000:02:00.0
       version: a1
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress vga_controller bus_master cap_list rom
       configuration: driver=nvidia latency=0
       resources: irq:34 memory:fa000000-faffffff memory:e0000000-efffffff memory:f0000000-f1ffffff ioport:e000(size=128) memory:c0000-dffff

如果在configuration这一行中有driver=nvidia的字符串，那么就说明nvidia的驱动安装ok
