I have an issue where my external monitor (ViewSonic) will not wake up. Why I think it's related to Fedora is the following:
Fedora recognizes the monitor's existence when I go into settings. However, the monitor will not turn on. I have tried xrandr with no luck. I have also tried Alt + F2 -> r with no luck. I have a docking station, but have also tried plugging the monitor directly into the computer. At first I thought it was related to plugging the monitor in before waking from sleep, but I just plugged it in while the machine was awake with the same experience. I would say this happens once every few days with no real pattern.

Which kernel is showing the problem, 5.2.x ot 5.1.y or both? In case you are running 5.2 version, can you try installing and/or booting with kernel 5.1.20-300.fc30.x86_64 and see if it works? In case then 5.1 works it can be related with the bugzilla I have opened https://bugzilla.redhat.com/show_bug.cgi?id=1744905 and you can add your info there.
