This article talk about graphics card installations. Installation can use two stages which are driver installation and device configuration. Sometimes, videocards are detected automatically (native support) but 3D acceleration support often need proprietary driver.
If you don't know your graphic card, visit hardware identification page to identify your card.
Technical words can be used but explained.
Installation of the free AMD/ATI graphics drivers (Recommended, typically the fastest and most stable, with full OpenGL and Vulkan support)
Installation of the proprietary "AMDGPU-PRO" graphics drivers published by AMD (Unsupported, generally poorer quality, and can cause instability with later system updates. Avoid using without good reason.)
