AMD graphics drivers are built into Ubuntu 26.04, so there is nothing to download. Update, confirm your Radeon card uses amdgpu with OpenGL and Vulkan, check video decoding, set up ROCm for AI, and fix a card stuck on llvmpipe or an older Radeon on the wrong driver.
Install NVIDIA drivers on Ubuntu 26.04 with sudo ubuntu-drivers install, choose the right version for your card including GTX 900 and GTX 10 series, run apps on the NVIDIA card in a laptop, and fix a black screen or a driver that will not load.
The first things to do after installing Ubuntu 26.04 LTS: install updates, get drivers now that Software & Updates is no longer installed, add codecs, turn on the firewall and set up backups. Then ten optional steps, from Flathub to free Ubuntu Pro.
