    Is it using any non-open-source drivers?

    When I installed Ubuntu, I gave permission to use proprietary drivers.

    Supposedly, the video hardware is AMD Radeon RX 580. Did Ubuntu use the open-source video driver or the proprietary one?

    How can I find out?

    A nice way to find out all your equipment is inxi. To install in terminal:
    Code:
    sudo apt install inxi
    then for a overall view enter:
    Code:
    inxi -b
    That gives an overall view. For more details replace the -b switch with -G and you get graphic details.

    For what it's worth, the open source AMD driver and the proprietary AMD driver are essentially exactly the same. The main difference is that the proprietary one uses the same shader compiler as their Windows driver. The old old proprietary AMD driver, fglrx, isn't used by anyone anywhere.

    It's only the nVidia driver where there's a fundamental difference between the proprietary one and the open source one.

    Here's what inxi -G says. How can I tell whether it's the open-source or proprietary driver?
    Code:
    Graphics:  Card: Advanced Micro Devices [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X]
               Display Server: x11 (X.Org 1.20.1 ) driver: amdgpu
               Resolution: 1920x1080@60.00hz, 1920x1080@60.00hz
               OpenGL: renderer: Radeon RX 580 Series (POLARIS10, DRM 3.26.0, 4.18.0-20-generic, LLVM 7.0.0)
               version: 4.5 Mesa 18.2.8

    I have heard the same.

    Well I guess that is how amd shows the driver "amdgpu". Which means nothing to me. See if this will better describe the driver:
    Code:
    sudo lshw -C display

    driver: amdgpu, so the open source one.

    The one with proprietary bits is amdgpu-pro.

    Will the amdgpu-pro show up in our drivers tab? Or is other magic necessary? PPA?

    I have no idea; I've never tried using AMD graphics. I don't think there's much performance difference between them.

    Re: Is it using any non-open-source drivers?

    In Ubuntu 18.04's Gnome desktop, if I press the Windows key and choose "Ubuntu Software", a box called "Software & Updates" appears. Inside it is a tab called Additional Drivers. It tells me, "No proprietary drivers are in use", which might be true, but it also says "No additional drivers available", which I hope just betrays a limited outlook.

    (According to the internet, only the proprietary driver supports OpenCL to use the AMD GPU as a computing device.)

    For inquiring minds, refer to this link for information about AMD amdgpu-pro, https://www.amd.com/en/support/kb/re...dpro-lin-16-40
