Hi all, in addition to font DPI settings, there is also the ability to scale the whole screen using xrandr. Currently there is no support for this from GUI, so it needs to be done manually. Read about it here (https://unix.stackexchange.com/questions/596887/how-to-scale-the-resolution-...) section "Scaling the desktop with Xorg X11". This scales everything, not just the fonts.
Cheers Michele
