Bug 1481407

GNOME _control-center_ rebased to version 3.26 In Red Hat Enterprise Linux 7.5, _control-center_ has been rebased to upstream version 3.26. Notable enhancements include: * *Night Light* is a new feature that changes the color of your displays according to the time of day. The screen color follows the sunrise and sunset times for a given location, or can be set to a custom schedule. *Night Light* works with both *X11* and *Wayland* display server protocols. * This update introduces a new layout to the *Settings* application. The grid of icons has been replaced by a sidebar, which allows switching between different areas. In addition, the *Settings* window is bigger and can be resized. * GNOME’s `Network` settings have been improved. `Wi-Fi` now has its own dedicated settings area and `Network` settings dialogs have been updated. * GNOME’s `Display` settings have been redesigned. The new design brings relevant settings to the forefront. With multiple displays connected, there is a row of buttons, which allows choosing the preferred use. The new `Display` settings include a preview version of a new scaling setting. This allows the size of what is shown on the screen to be adjusted to match the density (often expressed as PPI or DPI) of your display. Note that *Wayland* is recommended over *X11*, as per-display configuration is not supported on the latter. * The user interface of three other areas of the *Settings* application has been redesigned: `Online Accounts`, `Printers`, and `Users`.
