I have fractional scaling working at 150% on one display and 100% on the other. When I reboot, these settings are forgotten (as well as the relative position of displays).
How do I persist my settings? This is on Ubuntu 19.10.

To enable fractional scaling in GNOME 3.32 on Wayland run:
gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"
To enable fractional scaling in Ubuntu 19.04 on Xorg run:
gsettings set org.gnome.mutter experimental-features "['x11-randr-fractional-scaling']"
Once set, you can open
Settings > Devices > Screen Displayto access additional fractional scaling values, including 125% and 150%.
There are many reports of settings not persisting across reboots:

If that is the case simply use
Many use Ubuntu 16.04 with Unity Tweak tool and Font scaling options. For example I have mine set at
1.38 for many years without any problems.
