-  * :!: Using an AMD eGPU with a display attached doesn't seem to work reliably if the ''intel'' driver is being used ((for a very specific scenario, the Intel iGPU has to be active, manually set to use the ''intel'' Xorg DDX driver, an AMD GPU plugged into a Thunderbolt eGPU using the ''amdgpu'' Xorg DDX driver, with a 4K display plugged into it via HDMI))
