Looks like this is occurring on hybrid graphics systems. Not only Ubuntu, Arch, Fedora all affected by this bug. I have two Dell Latitude 5580 and Dell Latitude e5570 laptops. One has Intel+Nvidia hybrid graphic system and other one has Intel+ATi hybrid graphic system. Both having the same issue HDMi goes to sleep immediately after X server starts. The only desktop environment I found fixed this is Linux Mint Cinnamon and Mate both initially had the issue but after updating issue is gone. Looks like the bug is in the kernel.
