@SteeMan indeed this needs to be split in its own thread, but to sum up, I'd like to either have USB-C DP alt mode working on a current Armbian build (I tried and it does not seem to work but that would be the best outcome if it can work), or have 3D acceleration/video decoding acceleration on the 4.4 kernel as DP alt mode works on it. Thanks for the help to get the media kernel working, I'll try that when I have some time, thanks!
