X11 is quite able to advertise different DPI per output through XSETTINGS. GTK is able to grab Xft/DPI and use it for scaling (even for non-font stuff, though it will prefer to use Gdk/UnscaledDPI if available). GTK will watch the value and update the application if it changes. Applications can also subscribe to notifications for this value. While XSETTINGS can handle several screens, GTK only tracks one settings window and doesn't handle applications switching from one screen to another. Also, Ubuntu is now defaulting to Mir and the story doesn't seem better here since people are still requesting a better HiDPI support. I suppose that if support was implemented for Mir, it should be possible to make it work with X11 as well. -- Alas, how love can trifle with itself! -- William Shakespeare, "The Two Gentlemen of Verona"
