Graphics Driver

My PC runs on a AMD R9 280 GPU (yes I know it’s old). Other words to describe that are Southern Islands and GCN 1 (source). So I want to switch from the older radeon driver to the better amdgpu driver (which has Vulkan support). The Arch wiki principally explains how to do this, but on EndeavourOS with systemd boot, I had to do it slightly differently. This guide mentions what file to edit, but it doesn’t really mention the syntax, which is a bit different than the one mentioned in the Arch wiki.

Turns out I had to add the following to the end of the one-line file /etc/kernel/cmdline/, then run sudo reinstall-kernels and reboot.

amdgpu.si_support=1 radeon.si_support=0
