If you had problems with the HDMI output, I suppose that it must depend on the GPU model.

I have used Linux on many laptops and I never had problems with the video outputs, but most of them had NVIDIA GPUs and a few used the integrated Intel GPU. I have no recent experience with AMD GPUs on laptops.

I do not normally use Ubuntu, so that might matter, but when I bought a Dell Precision, it came with Ubuntu preinstalled and it worked fine until I wiped Ubuntu and I installed another Linux distribution.

I used once a Lenovo on which I had to waste a couple of days until I made the GPU work properly in Linux, because it was an NVIDIA Optimus switchable GPU, but even on that laptop there were no problems with the video outputs, but only with the OpenGL acceleration, until it was configured in the right way.
