It reports a variety of types, too-not just PCI hardware. You can also use the lshw command to list the hardware installed on a Linux computer. That’s useful info when more than one card is installed on a computer. The “” text at the end of the first line indicates this is the “operational” graphics card. The card is an NVIDIA Corporation GP108, and, after a few seconds with a search engine, we found the NVIDIA tech page for that device. It gave us a lot of good information right away!

Before we start, it’s wise to update the local copy of the PCI database. Wouldn’t it be great if we could tie the PCI database and the lspci command together? Well, actually, that’s exactly what happens when you run the lspci command. You can use the lspci command to list the PCI devices installed on a Linux computer, as well as some information about them. This means if you know some information about the device, you can look it up. The PCI ID Repository maintains a database of all known IDs for PCI devices.
The Peripheral Component Interconnect (PCI) standard is a common protocol you can use to talk to internal peripherals, such as graphics cards. It doesn’t matter! You can solve this conundrum either from the command line or through the graphical user interface (GUI). Let’s assume the worst-case scenario and say the drivers for the graphics card were never installed, so you can’t even look at those to get a clue.
