Thanks Broo...
I'm Using Linux GNOME 43 latest version
Brother their is any option through command line to change the display scale size in fraction.
Im not an user of Ubuntu.
I am using the gnome desktop.
My resolution is Full HD 1080p. When I set scaling to 100% it looks very small and when I set to 200% it looks very big. Is there any way to set in 125% or 150% in display scaling?
I don't want to use another desktop manager.
gnome is simple and easy to use.
