USB-C to HDMI Adapter disconnects/reconnects when gnome-control-center starts
I use 3 in 1 USB-C to HDMI Adapter to connect a second monitor to my HP Elite Book G8 workstation. The issue I am having is exactly the same as the creator of the following question on Ask Ubuntu (Stack Exchange): https://askubuntu.com/questions/1300652/usb-c-to-hdmi-adapter-disconnects-reconnects-when-gnome-control-center-starts
Basically what happens is whenever a Gnome Control Center is opened my second monitor which is connected through the 3-in-1 USB-C to HDMI adapter goes blank for a few seconds and then it reconnects. Few days ago I noticed that this also happens using the default application which comes with Ubuntu to play Videos (Totem). As a result I am not sure if this issue is directly related to the app itself or to some underlying technology which both application use.
Steps to reproduce:
- Have (3-in-1 / 7-in-1) USB C to HDMI adapter
- Open GNOME Settings
Outcome: Screen goes blank for several seconds
