I checked hwdata output in Unity Settings Displays menu with 2 different devices (vendors: LG and Dell) on LiveCDs for xenial, bionic, cosmic with the proposed patch installed (and with ubuntu-unity-desktop installed from universe in case of bionic and comsmic).
Worked as expected (i.e. in the Test Case section of the bug description).
