=== What is GNOME? ===

"GNOME 3 is an easy and elegant way to use your computer. It is designed to put you in control and bring freedom to everybody. GNOME 3 is developed by the GNOME community, a diverse, international group of contributors that is supported by an independent, non-profit foundation." — [http://gnome.org GNOME]
Starting with Portage-2.3.8, a switch to a new repository configuration framework is complete and users may want to update their configuration files. This document aims to describe the goals for the new framework and how to use it.


=== Prerequisites ===
== Multiple repository layout ==
One of the most important changes is the switch from the old ''overlay'' layout to a new cleaner ''repository'' system. The new layout is more flexible and more predictable. For example, repositories can now use resources (eclasses, for example) provided by other repositories.


==== From a Clean Install ====
The old layout was based on the concept of one ''main tree'' and optionally a number of overlays. The main tree provided base system ebuilds, eclasses, profiles, while overlays mostly were able to provide their own ebuilds. The ebuild provided by overlays overrode the ebuilds in main tree to the extend of making it impossible to install the main tree version. Overlays could also provide eclasses for their own ebuilds and package.* entries that applied to all overlays and to the main tree. The Package Manager is responsible for updating the main tree, while overlays are managed externally.


Ensure that the [[X Window System]] is installed.
The new layout is based on the concept of one or more configurable repositories. Each repository can either be stand-alone or depend upon other repositories. The distribution provides a repository called ''funtoo'' (a drop-in replacement for Gentoo's ''gentoo'' repository). Users can install more repositories at they will, the repositories providing their own ebuilds, eclasses and profiles as necessary and/or using them from other repositories. Users can explicitly choose the repository they want to install packages from. The Package Manager can update all repositories.


=== Preparing to emerge ===
== Portage configuration ==
=== New repository layout ===
The repository configuration should be stored in <code>/etc/portage/repos.conf</code>. It can be either a single file or a directory containing one or more ''.conf'' files.


To get your system ready to emerge gnome, first set your system flavor to desktop, and enable the gnome profile mix-in. To accomplish this, do the following:
The default configuration is installed as <code>/usr/share/portage/config/repos.conf</code>. This file is internal configuration file installed with portage ebuild and should '''not''' be modified. Instead, the configuration in <code>/etc/portage/repos.conf</code> can override the defaults specified there.


{{console|recipe=setup,setup-light|desc=Set profile|body=
The configuration uses format similar to Windows .ini files. Each section heading (repository name in square brackets) signifies a single repository, followed by one or more key-value option pairs. For example, the following file copies default configuration for Funtoo repository:
# ##i##eselect profile set-flavor funtoo/1.0/linux-gnu/flavor/desktop
# ##i##eselect profile add funtoo/1.0/linux-gnu/mix-ins/gnome
}}
 
By enabling the gnome mix-in, various USE and other settings will be optimized to provide you with a pain-free GNOME installation experience.
 
=== Emerging ===


You are provided with two packages that will pull in this desktop environment:
{{file|name=/etc/portage/repos.conf/funtoo.conf|desc=Example configuration override for Funtoo repository to move it to non-standard location|body=
 
[funtoo]
* ''gnome''
# moved to non-standard location!
 
location = /var/db/repos/funtoo
{{fancynote|This is the "whole shabang" - pulls in a range of applications made for the gnome desktop environment including a few games, an archive manager, a system monitor, a web browser, a terminal, etc.}}
sync-type = git
 
sync-uri = git://github.com/funtoo/ports-2015.git
* ''gnome-light''
auto-sync = yes
 
{{fancynote|As the name implies, this pulls in the base minimal you need to get a functioning GNOME Desktop Environment.}}
 
==== GNOME 3.14 from a clean install ====
 
===== gnome =====
 
To emerge ''gnome'' run the following command
 
{{console|recipe=setup|desc=Emerging GNOME|body=
# ##i## emerge gnome
}}
}}


===== gnome-light =====
The most useful repository configuration options are listed below:
;location: ''Obligatory.'' Specifies the directory where repository is/will be stored. If Portage knows how to sync the repository and the location does not exist, it will be created on next ''emerge --sync''. Otherwise, the directory must exist.
;priority: Specifies the priority used for ordering ebuilds from different repositories. If two repositories provide an ebuild with matching versions, the repository with higher priority will be used.
;auto-sync: Specifies whether ''emerge --sync'' should update the repository. Defaults to ''yes'' if ''sync-type'' is specified, ''no'' otherwise.
;sync-depth: Specifies ''--depth'' for git clone. Used only on initial sync. Defaults to 1. Can be set to 0 to force full clone (not pass ''--depth'' at all).
;sync-type: Specifies syncing/update method. Can be one of: ''cvs'', ''git'', ''rsync'', ''svn''.
;sync-umask: Specifies the umask used when updating/syncing the repository.
;sync-uri: Specifies remote URI from which the repository will be cloned/synced. Can use any syntax valid for a particular syncing method.
;sync-user: Specifies the user[:group] used to update/sync the repository. If ''FEATURES=usersync'' is used, defaults to the credentials of directory owner.


To emerge ''gnome-light'' run the following command
Additionally a <code>[DEFAULT]</code> section may be specified. Options in this section are used as defaults for all repositories.


{{console|recipe=setup-light|desc=Emerging a minimal GNOME environment (alternative)|body=
=== Migrating existing configurations ===
# ##i## emerge gnome-light
The new configuration format provides replacement for existing configuration done through <code>/etc/portage/make.conf</code> and environment variables. While the variables are still supported for backwards compatibility, users are recommended to move to the new configuration scheme. Funtoo portage ebuild is planned to  make the migration unattended (repos.conf installed automatically to ease the config steps) with the following file:
{{file|name=/etc/portage/repos.conf/funtoo.conf|body=
[funtoo]
location = /usr/portage
sync-type = git
sync-uri = git://github.com/funtoo/ports-2015.git
auto-sync = yes
}}
}}
The following replacements are provided for existing variables:
;PORTDIR: Used to specify main tree location. Replaced by ''location'' key in the section corresponding to the default repository (<code>[funtoo]</code> by default).
;PORTDIR_OVERLAY: Used to specify locations of overlays. Each of the paths needs to be replaced with a separate repository section, with the path placed in ''location'' key. Additionally, ''priority'' may be used to force specific ordering of ebuild overrides.
;SYNC: Used to specify URI for syncing the main repository, also implied a protocol for doing that. Replaced by the ''sync-uri'' and ''sync-type'' keys in the default repository section.
;SYNC_UMASK: Used to specify umask for syncing repositories. Replaced by ''sync-umask'' key in repository configuration. Can be specified in <code>[DEFAULT]</code> section to apply to all repositories.
;SYNC_USER: Used to specify user credentials for syncing repositories. Replaced by ''sync-user'' key in repository configuration. Can be specified in <code>[DEFAULT]</code> section to apply to all repositories.


==== Upgrading from GNOME 3.12 ====
{{file|name=/etc/portage/make.conf|desc=Example old make.conf file|body=
# user changed PORTDIR location
PORTDIR="/var/db/repos/funtoo"
PORTDIR_OVERLAY="/var/db/repos/foo /var/db/repos/bar"


To update either ''gnome'' or ''gnome-light'' run the following command:
SYNC="git://github.com/funtoo/ports-2015.git"
 
SYNC_USER="oleg"
{{console|body=
SYNC_UMASK="022"
# ##i## emerge -vauDN world
}}
}}
=== Subsystems ===


==== Bluetooth ====
{{file|name=/etc/portage/repos.conf|desc=Replacement repos.conf file|body=
[DEFAULT]
sync-user = oleg
sync-umask = 022


For bluetooth support, ensure that:
[funtoo]
location = /var/db/repos/funtoo
sync-type = git
sync-uri = git://github.com/funtoo/ports-2015.git


# Bluetooth support is enabled in your kernel (using modules is fine).
[foo]
# Your bluetooth hardware is turned on.
location = /var/db/repos/foo
# Add the <code>bluetooth</code> startup script to the default runlevel, and start it.
priority = 1


This can be done as follows:
[bar]
 
location = /var/db/repos/bar
<console>
priority = 2
# ##i##rc-update add bluetooth default
}}
# ##i##rc
</console>
 
Once this is done, you should now be able to navigate to ''Settings'' -> ''Bluetooth'' and turn bluetooth on. The icon next to devices should now animate and you should be able to discover and add devices such as keyboards.
 
{{Note|1=
Additional kernel drivers may need to be enabled for certain input devices. For example, for the bluetooth Apple Magic Trackpad, the following option must be enabled in your kernel:
 
{{kernelop|title=Device Drivers,HID support,HID bus support,Special HID drivers|desc=
<M> Apple Magic Mouse/Trackpad multi-touch support
}}}}
 
==== Printing ====
 
To enable printing support, add <code>cupsd</code> to the default runlevel:
 
<console>
# ##i##rc-update add cupsd default
# ##i##rc
</console>
 
You should now be able to navigate to ''Settings'' -> ''Printers'' and add printers to your system, and print.
 
==== Scanning ====
 
To enable scanning support, add your user account to the <code>lp</code> group. This will allow your user to access the USB scanner.
 
Then, <code>emerge xsane</code>, and run it. It should be able to access your scanner.
 
=== Finishing Touches ===
 
==== X ====
 
===== Setting up xdm (GUI log-in) =====
 
Typically, you will want to use <code>gdm</code>, the GNOME display manager, to log in to GNOME. This will allow you to log in graphically, rather than using the text console.


To enable gdm, edit <code>/etc/conf.d/xdm</code> and set <code>DISPLAYMANAGER</code> to <code>gdm</code> instead of <code>xdm</code>. Then, perform the following steps to add <code>xdm</code> to the default runlevel, and have it start automatically from now on when your system starts:
The <code>repos.conf</code> configuration can be further extended with ''sync-type'' and ''sync-uri'' for overlays to get ''emerge --sync'' updating them automatically.


{{Note|Funtoo's <code>/etc/init.d/xdm</code> initscript has been modified to start the requisite services <code>dbus</code>, <code>openrc-settingsd</code> and <code>consolekit</code> prior to starting <code>gdm</code>.}}
let's see a real example of tree and overlays added.
{{file|name=/etc/portage/repos.conf|desc=Replacement repos.conf file|body=


{{console|recipe=setup|desc=Enable the GNOME display manager|body=
[gentoo]
# ##i## rc-update add xdm default
location = /usr/portage
sync-type = git
sync-uri = git://github.com/funtoo/ports-2012.git
[funtoo-overlay]
location = /root/git/funtoo-overlay
[funtoo-gnome]
location = /root/git/funtoo-gnome-overlay
}}
}}
 
funtoo-overlay and funtoo-gnome-overlay are an overlays added on top of regular portage tree.
Then, if you want to start it now do:
[[Category:Portage]]
 
{{console|body=
# ##i##rc
}}
 
But you should reboot to avoid having an open login terminal.
 
===== Setting up xinitrc (text log-in) =====
 
Adding the following to your <code>~/.xinitrc</code> file is sufficient:
 
<pre>
# Fix Missing Applications in Gnome
export XDG_MENU_PREFIX=gnome-
 
# Properly Launch the Desired X Session
exec ck-launch-session gnome-session
</pre>
 
Additionaly, if you need support for different input sources, there is no longer a need to configure IBus or SCIM in your <code>.xinitrc</code> file as GNOME uses IBus natively. Simply configure it in the Control Center under Region & Language.
 
=== Automatically Starting Applications at Login ===
 
When using an old-fashioned <code>.xinitrc</code>, starting up applications when X starts is relatively easy. When using GDM, this can still be accomplished, by using the <code>~/.xprofile</code> file. Here's my sample <code>.xprofile</code> to start <code>xflux</code> to dim the screen at night:
 
<pre>
xflux -z 87107
</pre>
 
{{Note|Remember to add a <code>&</code> at the end of any command that doesn't return to the shell prompt after running.}}
 
=== games ===
Gnome has several games that can be added on to your install.  By default most games are not included in gnome's emerge.
 
Users wishing to play games need to be added to the games group:
{{console|body=###i## gpasswd -a $USER games}}
 
game list:
;gnome-sudoku
;gnome-mastermind
;gnome-nibbles
;gnome-robots
;gnome-chess
;gnome-hearts
;gnome-mahjongg
;gnome-mines
;gnome-klotski
;gnome-tetravex
 
game system emulators:
 
;gnomeboyadvance
;gnome-mud

   Warning

This article is a work-in-progress referring to a future Portage version. It does not apply to the current Funtoo Portage version. Please do not update your configuration yet.

Starting with Portage-2.3.8, a switch to a new repository configuration framework is complete and users may want to update their configuration files. This document aims to describe the goals for the new framework and how to use it.

Multiple repository layout

One of the most important changes is the switch from the old overlay layout to a new cleaner repository system. The new layout is more flexible and more predictable. For example, repositories can now use resources (eclasses, for example) provided by other repositories.

The old layout was based on the concept of one main tree and optionally a number of overlays. The main tree provided base system ebuilds, eclasses, profiles, while overlays mostly were able to provide their own ebuilds. The ebuild provided by overlays overrode the ebuilds in main tree to the extend of making it impossible to install the main tree version. Overlays could also provide eclasses for their own ebuilds and package.* entries that applied to all overlays and to the main tree. The Package Manager is responsible for updating the main tree, while overlays are managed externally.

The new layout is based on the concept of one or more configurable repositories. Each repository can either be stand-alone or depend upon other repositories. The distribution provides a repository called funtoo (a drop-in replacement for Gentoo's gentoo repository). Users can install more repositories at they will, the repositories providing their own ebuilds, eclasses and profiles as necessary and/or using them from other repositories. Users can explicitly choose the repository they want to install packages from. The Package Manager can update all repositories.

Portage configuration

New repository layout

The repository configuration should be stored in /etc/portage/repos.conf. It can be either a single file or a directory containing one or more .conf files.

The default configuration is installed as /usr/share/portage/config/repos.conf. This file is internal configuration file installed with portage ebuild and should not be modified. Instead, the configuration in /etc/portage/repos.conf can override the defaults specified there.

The configuration uses format similar to Windows .ini files. Each section heading (repository name in square brackets) signifies a single repository, followed by one or more key-value option pairs. For example, the following file copies default configuration for Funtoo repository:

   /etc/portage/repos.conf/funtoo.conf - Example configuration override for Funtoo repository to move it to non-standard location
[funtoo]
# moved to non-standard location!
location = /var/db/repos/funtoo
sync-type = git
sync-uri = git://github.com/funtoo/ports-2015.git
auto-sync = yes

The most useful repository configuration options are listed below:

location
Obligatory. Specifies the directory where repository is/will be stored. If Portage knows how to sync the repository and the location does not exist, it will be created on next emerge --sync. Otherwise, the directory must exist.
priority
Specifies the priority used for ordering ebuilds from different repositories. If two repositories provide an ebuild with matching versions, the repository with higher priority will be used.
auto-sync
Specifies whether emerge --sync should update the repository. Defaults to yes if sync-type is specified, no otherwise.
sync-depth
Specifies --depth for git clone. Used only on initial sync. Defaults to 1. Can be set to 0 to force full clone (not pass --depth at all).
sync-type
Specifies syncing/update method. Can be one of: cvs, git, rsync, svn.
sync-umask
Specifies the umask used when updating/syncing the repository.
sync-uri
Specifies remote URI from which the repository will be cloned/synced. Can use any syntax valid for a particular syncing method.
sync-user
Specifies the user[:group] used to update/sync the repository. If FEATURES=usersync is used, defaults to the credentials of directory owner.

Additionally a [DEFAULT] section may be specified. Options in this section are used as defaults for all repositories.

Migrating existing configurations

The new configuration format provides replacement for existing configuration done through /etc/portage/make.conf and environment variables. While the variables are still supported for backwards compatibility, users are recommended to move to the new configuration scheme. Funtoo portage ebuild is planned to make the migration unattended (repos.conf installed automatically to ease the config steps) with the following file:

   /etc/portage/repos.conf/funtoo.conf 
[funtoo]
location = /usr/portage
sync-type = git
sync-uri = git://github.com/funtoo/ports-2015.git
auto-sync = yes

The following replacements are provided for existing variables:

PORTDIR
Used to specify main tree location. Replaced by location key in the section corresponding to the default repository ([funtoo] by default).
PORTDIR_OVERLAY
Used to specify locations of overlays. Each of the paths needs to be replaced with a separate repository section, with the path placed in location key. Additionally, priority may be used to force specific ordering of ebuild overrides.
SYNC
Used to specify URI for syncing the main repository, also implied a protocol for doing that. Replaced by the sync-uri and sync-type keys in the default repository section.
SYNC_UMASK
Used to specify umask for syncing repositories. Replaced by sync-umask key in repository configuration. Can be specified in [DEFAULT] section to apply to all repositories.
SYNC_USER
Used to specify user credentials for syncing repositories. Replaced by sync-user key in repository configuration. Can be specified in [DEFAULT] section to apply to all repositories.
   /etc/portage/make.conf - Example old make.conf file
# user changed PORTDIR location
PORTDIR="/var/db/repos/funtoo"
PORTDIR_OVERLAY="/var/db/repos/foo /var/db/repos/bar"

SYNC="git://github.com/funtoo/ports-2015.git"
SYNC_USER="oleg"
SYNC_UMASK="022"
   /etc/portage/repos.conf - Replacement repos.conf file
[DEFAULT]
sync-user = oleg
sync-umask = 022

[funtoo]
location = /var/db/repos/funtoo
sync-type = git
sync-uri = git://github.com/funtoo/ports-2015.git

[foo]
location = /var/db/repos/foo
priority = 1

[bar]
location = /var/db/repos/bar
priority = 2

The repos.conf configuration can be further extended with sync-type and sync-uri for overlays to get emerge --sync updating them automatically.

let's see a real example of tree and overlays added.

   /etc/portage/repos.conf - Replacement repos.conf file
[gentoo]
location = /usr/portage
sync-type = git
sync-uri = git://github.com/funtoo/ports-2012.git
 
[funtoo-overlay]
location = /root/git/funtoo-overlay
 
[funtoo-gnome]
location = /root/git/funtoo-gnome-overlay

funtoo-overlay and funtoo-gnome-overlay are an overlays added on top of regular portage tree.
