You can easily preview all the specifications related to your system in Ubuntu Linux using HardInfo.
You can access it one of two ways: performing a search for the HardInfo package in the Software Center, or opening via the Command Line.
- For the Command Line approach, click the Ubuntu icon in the upper-left corner of the screen and type in Terminal, then press Enter. You could also opt to simultaneously press Ctrl+Alt+T to open the Command Line.
- Enter the command sudo apt-get install hardinfo into the terminal and press Enter to open the tool.
- Once HardInfo has been opened, navigate to Device > DMI page inside the tool to preview the motherboard manufacturer and model.
