Linux desktop and high resolution laptops

"setting a scale factor of two" is a much too simple logic IMO. There
should be a number of scaling option (a logarithmic scale for this would

Besides I am the user and I want controls (per monitor if there is more
than one) so that I can tune it to my taste, the quality of my monitor(s)
and the applications I use. It is OK that the desktop has a reasonable
default, of course, but user controls could be at least "very_small ..
small ..normal/default .. large ..very_large" for instance. System should
not take control(s) away from user.

I accept that there is an ongoing process, and it is not simple nor
trivial. Various mainstream Linux desktops should agree on a common
mechanism (so that it will work for KDE applications running in Gnome, for
instance). But that is of course also not easy. I don't think the
developers of different desktops communicate much and they use different
'abstraction layers' (various versions of qt and GTK as well as X11 versus
Wayland (soon)) for development.
