Comment 3 for bug 1521000

I can confirm the following in my experiences with 17.04 and 17.10:

"The problem with the "Configure new displays when connected" setting is that it unfortunately also triggers xfce4-display-settings on other events like plugging your laptop on the charger or waking it up from hibernation."

Everytime my monitor sleeps, I'm presented with the xfce4-display-settings dialog. However, I'm also seeing my display settings being reset to default values at the same time as the xfce4-display-settings dialog appears. They aren't remembered.

With multiple monitors, monitor position is not remembered.

Screen resolution is not remembered.
