GNOME doesn't remember monitor settings/layout

[Ian Johnson]

I'm not sure if this is an Xorg issue or something else, but basically I have enabled fractional scaling in my Disco Dingo install and upon rebooting the scaling and the layout of the monitors is forgotten. I have 2 identical Samsung monitors + 1 LG monitor where the LG and 1 of the Samsung monitors are connected via DisplayPort and the 2nd Samsung monitor is connected over HDMI. My GPU is an NVIDIA Titan X (Maxwell architecture) and I am using the recommended nvidia-driver-418 package.

On the same system on a different disk I have Ubuntu 18.04 Desktop installed which does not have this issue.
