Black screen when reducing screen resolution
Using Dell Precision M3800 i7-4712HQ/Fedora 30/5.0/Gnome-shell mutter 3.32.0 or 3.32.1 When i reduce screen resolution from 3840X2160 (default) to any resolution, when i apply the setting a black screen appears. If i suspend the machine and activate it again, it works as intended. Also If i power off or restart the machine with the "reduced: resolution, login screen appears normally but when i try to log in to my account with the "reduced" resolution , black screen appears again. The suspend , reactivate trick works again. Feel free to ask me for logs
PS : i reduce screen resolution to have smooth 60fps UI
