== GNOME ==
== GDM on Wayland ==
The Gnome Display Manager (GDM) in Fedora 22 will default to the Wayland display server instead of Xorg.  While the default GNOME session still uses X, this change brings the move to Wayland one step closer.


Fedora 15 includes GNOME 3. It brings the first major overhaul of the GNOME user experience in 10 years. As with the GNOME 2.0 platform, the GNOME 3.0 release is the starting point for a long trajectory of advances in the state of the free desktop.
Wayland is a compositing display server, using your computer's video hardware for rendering. On systems where Wayland will not run, GDM should transparently fall back to using the X backend.


The new GNOME Shell is a new way for users to interact with their systems and be productive. The shell features a completely redesigned interface and tools for elegance and ease of use:
If you need to disable Wayland for GDM, edit '''/etc/gdm/custom.conf''' to reflect the following:
* A top bar that provides immediate access to settings, calendar, and major hardware
* An Activities hot corner that provides easy access to all applications and searching, as well as a dock for favorite apps
* Notification improvements, such as messaging support without having to switch context to another application
* Access throughout the shell for keyboard-centric as well as point-and-click users
* A control panel that integrates system and personal settings in one location
* Many other improvements; complete information is available at http://live.gnome.org/GnomeShell
There is an excellent upstream wiki page that describes the major changes and explains different workflows. For details, refer to http://live.gnome.org/GnomeShell/CheatSheet.


The new GNOME 3 user experience requires a video card capable of 3D acceleration. Fedora 15 supports the widest possible range of these cards through free software drivers, including the ''nouveau'' driver for NVidia graphics cards, the ''radeon'' driver for ATI graphics cards, and the ''intel'' driver for Intel graphics cards. 
    [daemon]
    WaylandEnable=false


GTK+ 3.0 is also part of Fedora 15, which features numerous enhancements for application developers.  Changes in the toolkit include:
== Libinput used for input devices ==
* Modernized handling of input devices
Input devices in supporting environments, notably GNOME with Fedora Workstation and KDE, will use a new driver, '''libinput'''.  The new driver replaces a variety of drivers, such as '''synaptics''', enabling more consistent behavior across a variety of devices.  
* Improved and simplified drawing through Cairo rather than wrappers around old X11 methods
* A new theming API with a familiar CSS syntax
* Early stages of easier application support, such as window tracking and ensuring uniqueness
* and many more improvements.


Users will notice the following changes in the environment:
'''libinput'' improves support for multi-touch devices and software emulated buttons. The driver is implemented directly in wayland sessions, and in X sessions through the '''xorg-x11-drv-libinput''' wrapper.
* The desktop workspace no longer displays the contents of the user's ''~/Desktop'' directory. That directory and its content are still accessible through the Files application.


Input devices will be configurable through '''GNOME Settings''', '''KDE System Settings''', '''xfce-settings''', or '''xinput'''.  Some niche features are not available via '''libinput''', but the previous behavior can be restored by removing the '''xorg-x11-drv-libinput''' package, and ensuring the appropriate x11 driver packages, probably x11-drv-synaptics or xorg-x11-drv-evdev are installed.


Advanced users can install ''gnome-tweak-tool'' to customize desktop environment.
Note that '''xorg-x11-drv-libinput''' is only installed by default on new Fedora 22 installations, if you're upgrading and you want to use the new features provided by libinput, you can install '''xorg-x11-drv-libinput''' manually by doing:


==Xfce==
    sudo dnf install xorg-x11-drv-libinput
 
Fedora 15 sees the introduction of Xfce 4.8. This new release remains true to Xfce's goal of providing a fast, lightweight yet user-friendly desktop environment, while adding a range of new features and incremental improvements:
 
* '''Remote share browsing''': Thunar, Xfce's file manager, now has support for GVFS, allowing easy remote access to files and folders on Windows shares and FTP, Webdav and SSH servers;
* '''New Xfce Panel''' with improved positioning and size handling, alpha transparency, a new item editor and drag'n'drop launcher creation;
* '''New Panel plugins''' such as '''window buttons''', which merges the features of the icon box and the tasklist into a single configurable plugin, and '''directory menu''', allowing quick browsing of a folder's tree structure;
* '''Easy application menu editing''' with any Freedesktop-compliant menu editor, such as Alacarte;
* '''Improved multihead display configuration''' including a quick setup dialog;
* '''Improved keyboard layout selection''' - wave goodbye to cryptic langauge/variant codes, and select the keyboard layout for your language in your language!
* And, in the venerable tradition of Xfce releases, a new clock mode - '''fuzzy clock mode!'''
 
== KDE ==
 
This release features KDE 4.6.
 
KDE 4.6 is the latest release of KDE 4. There are many enhancements and new features.
 
== Sugar ==
 
Sugar has been updated to the latest version 0.92 in Fedora 15. This
version provides major usability improvements for the first login
screen and the control panel, as well as new features such as support
for 3G networks.

GDM on Wayland

The Gnome Display Manager (GDM) in Fedora 22 will default to the Wayland display server instead of Xorg. While the default GNOME session still uses X, this change brings the move to Wayland one step closer.

Wayland is a compositing display server, using your computer's video hardware for rendering. On systems where Wayland will not run, GDM should transparently fall back to using the X backend.

If you need to disable Wayland for GDM, edit /etc/gdm/custom.conf to reflect the following: 

   [daemon]
    WaylandEnable=false

Libinput used for input devices

Input devices in supporting environments, notably GNOME with Fedora Workstation and KDE, will use a new driver, libinput. The new driver replaces a variety of drivers, such as synaptics, enabling more consistent behavior across a variety of devices.

'libinput improves support for multi-touch devices and software emulated buttons. The driver is implemented directly in wayland sessions, and in X sessions through the xorg-x11-drv-libinput wrapper.

Input devices will be configurable through GNOME Settings, KDE System Settings, xfce-settings, or xinput. Some niche features are not available via libinput, but the previous behavior can be restored by removing the xorg-x11-drv-libinput package, and ensuring the appropriate x11 driver packages, probably x11-drv-synaptics or xorg-x11-drv-evdev are installed.

Note that xorg-x11-drv-libinput is only installed by default on new Fedora 22 installations, if you're upgrading and you want to use the new features provided by libinput, you can install xorg-x11-drv-libinput manually by doing: 

   sudo dnf install xorg-x11-drv-libinput

To learn about the features and behavior of libinput, refer to man libinput or http://wayland.freedesktop.org/libinput/doc/latest/pages.html
