You can install the 16.04 kernel in 14.04 (https://wiki.ubuntu.com/Kernel/LTSEnablementStack <https://wiki.ubuntu.com/Kernel/LTSEnablementStack>) and you could try that to see if the same issue occurs, and easily roll back if it does. Alternatively it could be a difference in the graphics drivers between the two versions, which you could investigate.

I’ve found out that when you get to Mythbuntu 14.04.5 you have the same issues as 16.04.  I did a fresh install of Mythbuntu 14.04.5 and have the same blanking issues as in 16.04.  Seems Ubuntu brought the xorg and kernel in line with the versions on 16.04 and that’s where the problem is, I bet.
