In all my years I have yet to see HDMI output from a laptop to a monitor work on the first try in Ubuntu. Always need to install the proprietary drivers for that to work at all. If it can't even do that without a headache, after 10+ years of Linux use, I would call that a Linux problem, not a hardware problem. My colleagues seem to run into the same issue frequently as well. This article seems kind of ignorant. I'm g…
What Laptop is this? I never had an issue with the external outputs on any laptop I owned (and I've been running Linux since the 90s). I also don't know anyone who had these issues. The main issues I had were typically docking stations and suspend (but that has been super stable for my last 3 laptops).
It was a muxed setup. The screen was switched back and forth between GPUs and one would power off as needed (assuming everything went well). The HDMI port was only connected to the discrete GPU. T here was no way to get video out on the Intel card. By default, Linux would power on both, but use the Intel.
This was well before any AMD cooperation, and I had the laptop much longer than the FGLRX setup was supported. The open source Intel driver and simply turning off the AMD card was eventually the only way I could get it to run.
Even in Windows it was a strange setup. You had to manually switch, and when you did the screen would turn black, you'd wait a few seconds, and now you were on the other GPU.
I'm sure the situation is better these days, but after that experience I just stick to integrated.
