    Open source driver Vs. Closed source driver?

    Hiya!

    How to check if Ubuntu 20.04 LTS is using an open source driver or a closed source driver for AMD graphics?

    Thanks!

    No need.

    AMD drivers are open-source since many years ago.

    Re: Open source driver Vs. Closed source driver?

    AMD graphics on Linux use amdgpu -- open source developed by AMD -- or radeon -- open source, developed by the community with AMD's help. Each supports a different group of physical GPUs.

    Which is used is determined at install time and the correct module is loaded. There is nothing for you to worry about.

    Just as an aside, however, AMD has a proprietary overlay/add-on to amdgpu, which is called AMDGPU-PRO. That is really unnecessary for the vast majority of users and only works with certain GPUs.

    Re: Open source driver Vs. Closed source driver?

    One thing to note, however, is that because of the different development schedules it may take some time before the driver updates for the latest AMD graphics hardware are actually available through the repositories of your Linux distro of choice.

    It's always a good idea to ask about specific hardware...in my case, I'm not sure where Ubuntu 20.10 is in terms of drivers for the latest generation of AMD's GPUs (6700,6800 and XT variants).

    Thanks!

    I was also wondering how can one see GPU utilization on Ubuntu just like the Task Manager on Windows 10.

    Are there any terminal commands or application for that?

    Edit: @rbmorse it's Vega 11 Graphics. This is an AMD Ryzen 5 3400GE APU.

    you are using AMDGPU driver. if you see a display (desktop), then it is utilised.

    if you want to measure performance you can use phoronix test suite. it comes with a bunch of benchmark tests.

    drivers for vega are in built into kernel because they are opensource.

    here is a bit more information on the kernel switches and links to a few GUI apps: https://wiki.archlinux.org/index.php/AMDGPU

    in short - if you like graphs:
    WattmanGTK — A GTK GUI tool to monitor your GPU's temperatures P-states
    TuxClocker — A Qt5 monitoring and overclocking tool.
    Read the easy to understand, lots of pics Ubuntu manual.
    Do i need antivirus/firewall in linux?
    Full disk backup (newer kernel -> suitable for newer PC): Clonezilla
    User friendly full disk backup: Rescuezilla

    Thanks! But I really wanted to learn how to identify which graphics driver is installed on Linux since there is not only AMD.

    Would it be "lspci" in terminal?

    The inxi utility (apt install inxi) run with the -G switch will show you that.

    Wow, thank you very much! This tool is great!

    Why is inxi giving me these errors on Lubuntu?
