The display settings for GNOME hasn’t seen a major change since before 3.0, so with the design help of Allan Day, I had the chance to completely update the interface for 3.10. The interface now follows the new visual style of the other settings panels and simplifies tasks such as setting the primary display. It also includes simpler and clearer display indicators. Full details of the redesign, including the mockups, are available on the wiki page. Not everything is complete yet; “presentation mode” needs some additional support from the windowing system before it can be implemented. However, Wayland support is now available thanks to Giovanni Campagna’s work on Mutter and gnome-desktop, which also includes a new confirmation dialog provided by gnome-shell.
