Use lspci to view hardware on Linux

Check out the lspci command to see the hardware that Linux was able to recognize.

The lspci is useful for showing all the information about system PCI buses and the devices connected to them.

Your most common options are:

  • -v Shows detailed information about all devices.
  • -vv shows even more information about the devices.
  • -n Shows the codes of the manufacturers and devices.
  • -x Shows the first 64 bytes of the PCI configuration in hexadecimal.
  • -xxx Shows the entire PCI configuration in hexadecimal.
