Since I upgraded to High Sierra, my 2-display layout gets reset to side-by-side every time I reboot, when instead it should be vertical to match the physical layout of my monitors.
While potentially unrelated, High Sierra also lost my Login Items after the upgrade.
I'm using a MacBook Pro (15-inch, 2017), running 10.13.
How can I get High Sierra to remember my display layout?

Your MBP uses Non-Volatile Random-Access Memory (NVRAM) to store various settings. It may be worth resetting this.
To reset the NVRAM on all Late-2016 and 2017 MacBook Pro models (with and without Touch Bar) follow these steps:
Note 1: When you log back in you may need to readjust some of your system preferences (e.g. speaker volume, screen resolution, startup disk selection, time zone information, etc).
Note 2: If your Mac is using a firmware password, you will need to disable the firmware password before resetting NVRAM.
