[Solved] Black Screen on Mojave with RX 580

[accelito]

Hi

Last week I upgrade from HS to Mojave thought App Store and after installation I am getting black screen before the login screen.
Today I realized that if I left the computer to sleep when it comes after sleep I have video and everything is find.
Can somebody give ideas of how to fix it?

This is my configuration
Mobo: Gigabyte Z68p-ds3
GPU: MSI Radeon RX 580 4GB
CPU: Intel i5-2500

Attached my EFI Folder

After Sleep i got this in the system information:

Try to remove SSDTGFX from ACPI/patched

I tried, and same output.

Ok. as Radeon Guide you should put in your config.plist Graphics- RadeondeInit true

I did it, i got same results, black screen.
Still working if i left the computer go to sleep and wake up.

I use WhatEvergreen and Lilu, I use DP ports, no issues, nothing needed in config.plist other then enabling the onboard IGPU

Currently i am using HDMI and DVI, i'll try display port and post the results.
