I have a question about Fractional Scaling, I've tried recently PopOS Alpha 24.04, with their new Cosmic, and they have a usefull option about Fractional Scaling. We can adjust it to 50%, 75%, 100%, 125%...
I could adjust it on my 1366x768 screen to fit like a 1920x1080 screen...
You can activate Fractional Scaling in Settings>Displays. There is a Toggle to activate it. Then You have these in-between Steps. But it starts - at least in my Case - with 100% not with 50%. But from 100 in 25er Steps.
You can use xrandr to set such a individual scaling factor, but you can't use it in Wayland and should switch to Xorg (logout and at login click on your username then a cog wheal appears at the bottom right corner, there select "Zorin Desktop on Xorg")
