For GNOME 3, the GNOME Project has started from scratch and created a completely new, modern desktop designed for today's users and technologies. In GNOME 3:
- There is a new default modern visual theme and font
- The Activities view which provides an easy way to access all your windows and applications
- Built-in (integrated) messaging desktop services
- A more subtle notifications' system and a more discreet panel
- A fast Activities' search feature
- A new System Settings application
- ... and more features like: window tiling (Aero Snap like), an improved Nautilus etc.
[more details on the GNOME3 website]
GNOME3 comes with two interfaces, gnome-shell(standard) and fallback mode. gnome-session will automatically detect if your computer is capable to run gnome-shell and it would start the fallback mode if not.
Fallback mode is the old GNOME2 layout and is using gnome-panel(gtk3 port) + metacity
Using fallback mode you can still change the window manager with your preferred one.
Upgrade from the current gnome 2.32
Enable testing repo. Edit /etc/pacman.conf and uncomment testing.
#testing uncommented [testing] Include = /etc/pacman.d/mirrorlist
# pacman -Syu
You will end up with a system that has gnome 3.0 fallback mode. To install the new shell:
# pacman -S gnome-shell
Installing to a new system
Enable testing in the same way as above.
# pacman -S testing/gnome
For additional applications
# pacman -S testing/gnome-extra
Daemons and modules needed by GNOME
The GNOME desktop requires one daemon, DBUS for proper operation.
To start the DBUS daemon:
# /etc/rc.d/dbus start
Or add these daemons to the DAEMONS array in Template:Filename so they will start on boot up, e.g.:
DAEMONS=(syslog-ng dbus network crond)
GVFS allows the mounting of virtual file systems (e.g. file systems over FTP or SMB) to be used by other applications, including the GNOME file manager Nautilus. This is done with the use of FUSE: a user space virtual file system layer kernel module.
To load the FUSE kernel module:
# modprobe fuse
Or add the module to the MODULES array in Template:Filename so they will load at boot up, e.g.:
For a better desktop integration is recommended GDM.
# pacman -S gdm
Check out Display_Manager to learn how to start it correctly.
exec ck-launch-session gnome-session
Now GNOME will start when you enter the following command:
Using the shell
# pacman -S gnome-tweak-tool
This tool can customize fonts, themes and some other useful settings like action when lid is closed.
Enabling fallback mode
Your session would start automatically to fallback mode if gnome-shell is not present. If you want to enable it while having gnome-shell installed, open gnome-control-center. Open System Info > Graphics. Change Forced Fallback Mode to ON.
Gnome 3.0 hides a lot of useful options and you have to use dconf-editor to customize them.
For now, the Shutdown option seems to be hidden if the user presses the Status menu on the upper right. If you want to shutdown your system through the Status menu, click on it and then press the Alt button. The "Suspend" option will instantly turn into "Power off...", as long as you press the Alt button, which will allow you to properly shutdown your system.
Enabling integrated messaging
Empathy, the engine behind the integrated messaging, and all of the system settings based on your messaging accounts will not show up unless the telepathy group of packages or at least one of the backends (telepathy-gabble, or telepathy-haze, for example) is installed. These are not included in the default Arch GNOME installs and the Empathy interface doesn't give a nice error message, it just fails to work silently. You can install them:
# pacman -S telepathy
