Long black screen during boot on Ubuntu 18

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.
