The next version of Ubuntu is expected to ship with the GNOME Shell desktop environment. In an effort to make the GNOME desktop scale well across a wide range of devices, Canonical will be hosting a conference for developers to work on GNOME's HiDPI support. The OMG Ubuntu site shares: "Canonical is playing host to a 'fractional scaling hackfest' in its Taipei offices this week. Both GNOME developers and Ubuntu developers are in attendance. The aim: improve GNOME HiDPI support. Ubuntu's Unity desktop (I'm told, anyhow) plays fairly nice with high DPI monitors because the shell supports fractional scaling (though most apps, I believe, do not). Furthermore, users can tweak some high DPI settings to better suit their display(s). GNOME Shell also supports HiDPI monitors, but has, until now, been a little less flexible about it." Additional information on HiDPI support can be found in this blog post by Matthias Classen.
