I have tried multiple Linux distributions on this machine and all of them have something in common: suspend doesn't work.
Ubuntu 19.04 runs the best so far (sound card is dealt with correctly, every second boot performance is what it should be, etc) but suspend does not even work right there. When I do suspend and try to come out of suspend my screen is filled with non-legible "static".
Recently I have been using Manjaro 18.0.4 as I have had interesting suggestions on Manjaro forums: https://forum.manjaro.org/t/suspend-results-in-non-legible-screen-acer-predator-helios-500-ryzen/77603/7

He suggests obtaining the EDID and enforcing it through a kennel parameter. I have tried hwinfo -- monitor and get-edid and neither seems to get the correct data being that this is a 144Hz display and these utilities think it is a 60Hz display.

So does anyone have any suggestions for this problem or in how to get a legit edid either in Linux or Windows 10?
