Up until now, I used Ubuntu 16 and everything worked fine. But then I did a clean install of Ubuntu 18 and now I am faced with a quite annoying problem.
Every time I turn on my computer, then during Ubuntu boot process the screen goes black, the computer does nothing, this continues 2 minutes, and then the PC continues to boot normally.
How can I fix this issue? I am using an HD5850 GPU with ubuntu drivers and have no extra hardware installed.
Here is the blame log

I may have found an answer, someone else asked a similar question with my experience of upgrading to 18 AND doing a fresh install.
I did this and it completely solved my blank screen problem that took minutes. Hopefully it solves it for you?
