In Windows, there are many software that you can use to check detailed information about your system hardware (CPU, mainboard, memory/ram, graphics cards, sound devices, etc.) such as CPU-Z, Blackbox, Speccy, etc. In Linux, we also have a considerate number of applications and command line tools for checking hardware information of a machine.

In this article, we will see only three of them which are compatible with the following Ubuntu/Linux Mint distributions:

  • Ubuntu 12.10/12.04/11.10
  • Linux Mint 14/13/12
   1. i-Nex

i-Nex is CPU-Z alternative for GNU / Linux. You can install it under Ubuntu or Linux Mint with these commands:

sudo add-apt-repository ppa:i-nex-development-team/daily 
sudo add-apt-repository ppa:nemh/gambas3 
sudo apt-get update 
sudo apt-get install i-nex


   2. CPU-G

CPU-G is another application having similar functions as CPU-Z. To install it, run these commands:

sudo add-apt-repository ppa:cpug-devs/ppa 
sudo apt-get update 
sudo apt-get install cpu-g


   3. lshw

You can also use lshw to check information about the hardware of your machine. To install lshw in Ubuntu/Linux Mint, open the terminal and run this command:

sudo apt-get install lshw lshw-gtk

To check your hardware on the terminal, use this command:

sudo lshw

To check hardware information from a GUI, run this command:

lshw -X

If you know a good software for listing hardware information under Ubuntu, you can mention it below.
