Issue/Bug Description: Usually I use 3 monitors in extended mode and when I first boot and then I plug in them is all ok. When the pc go in blank screen and I need to re-login two of the monitors show the same things, and are not extended like before blank screen.

I run into this as well. Have an external monitor plugged into my laptop.

If my laptop or monitor goes to sleep - when it wakes up - Pop forgets all my dual display settings. I then have to open settings, reselect my primary monitor, set my scaling etc.

@jimpriest You posted the same comment in https://github.com/pop-os/pop/issues/226#issuecomment-1048956644. That issue reports a workaround is to disable the HiDPI Daemon. Does turning the HiDPI Daemon Enabled switch off in the Displays settings page stop the issue from happening on your machine?

@jacobgkau No change. Updated settings and went to lunch. Came back, jiggled my mouse and the laptop screen woke up. The external monitor did not. Then I had to go to display settings, change the primary monitor (have to do this twice before it actually switches the to the external monitor). Then I have to reset my display scaling settings.
