Bug Description
Specific behavior:
When I "wake up" my computer (it is not in "Suspend", just "sleeping"), and both screens awaken, they are _effectively_ mirrored. I log in (see all display and inputs identically on both screens), open `nvidia-settings`, and go to "X Server Display Configuration". It appears to only display one screen. However, if I grab that screen and drag it to the right, it is revealed that the second display has just been set to sit atop the first display. Once I re-place the second screen to the right of the first, and click "Apply", things are fine until next time.
My screens are "Dell Display 24"s (DELL P2419HC) and are identical. One is connected via Display Port and the other is connected via HDMI. They are set to 1920x1080. I'm running NVidia drivers 470.129.06 on an NVidia GeForce GTX 960.
If I merely lock the screen (Super + L), it _does_ lock the screen and shut the screens off, and I have to sign back in, but this does _not_ reproduce the bug.
The buggy behavior consistently happens when the screens shut off on their own after a period of time (presumably from power saving or an idle timeout). The displays are shut off at the OS level, and then the screens themselves (getting no signal) go to sleep.
