External monitor randomly not waking up - users - Fedora Mailing-Lists

Thursday, 22 August 2019

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.

Machine info:
Lenovo T470s
Fedora 30
Gnome: 3.32.0
