36 <p>
37 The <uri link="http://www.gnome.org">GNOME</uri> project is a free software
38 project dedicated to the development of GNOME, a Unix/Linux desktop suite and
39 development platform. The <uri link="http://foundation.gnome.org">GNOME
40 Foundation</uri> coordinates the development and other aspects of the GNOME
41 Project.

51 GNOME is a desktop environment and a development platform. This piece of free
52 software is the desktop of choice for several industry leaders. It is
53 interesting both for business users, home users as well as developers.

62 <p>
63 Like with any big free software project, GNOME has an extensive user- and
64 development base. <uri link="http://planet.gnome.org">GnomePlanet</uri> is
65 a popular blog aggregator for GNOME hackers and contributors whereas <uri
66 link="http://developer.gnome.org">Developer.Gnome.Org</uri> is for the GNOME
67 developers. <uri link="http://library.gnome.org/users/">GNOME Library</uri>
68 contains a huge list of GNOME resources for end users. The <uri
69 link="http://worldofgnome.org/">World of GNOME</uri> is also a popular
70 aggregator for GNOME-related news.

79 <title>What do you need?</title>
80 <body>
81
82 <impo>
83 First read and follow the instructions in the <uri
84 link="/doc/en/xorg-config.xml">X Server Configuration Howto</uri> to setup your
85 X environment.
86 </impo>
87
88 <p>
89 Before you start installing GNOME, you might want to edit your USE variables.
90 Make sure that <c>X</c>, <c>gtk</c>, and <c>gnome</c> are in your USE variable
91 listed in <path>/etc/portage/make.conf</path>. If you want support for <c>dbus</c>, a
92 system message bus Gnome uses extensively, add it to your USE flags. If you
93 don't want KDE support (the other big desktop environment), remove <c>qt4</c>
94 and <c>kde</c>.
95 </p>
96
97 <pre caption="Example USE in /etc/portage/make.conf">
98 USE="-qt4 -kde X dbus gtk gnome"
99 </pre>
100
101 <p>
102 You can add the <c>branding</c> USE flag to get a lovely Gentoo-branded
103 splashscreen instead of the default Gnome splashscreen:
104 </p>
105
106 <pre caption="Enabling Gentoo branding">
107 # <i>echo "gnome-base/gnome-session branding" &gt;&gt; /etc/portage/package.use</i>
108 </pre>
109
110 <note>
111 If you use the <c>desktop</c> profile, these USE flags will be set for you. You
112 can check your profile by running <c>eselect profile list</c> and <c>eselect
113 profile set &lt;profile-name&gt;</c> as root.
114 </note>
115
116 <p>
117 Once done, start installing GNOME by emerging <c>gnome</c>:
118 </p>
119
120 <pre caption="Installing GNOME">
121 # <i>emerge gnome</i>
122 </pre>
123
124 <p>
125 You can also opt for a minimal Gnome installation using <c>gnome-light</c>.
126 If you do so, you will have a lightweight Gnome installation without
127 the additional tools that a full Gnome installation provides so you might need
128 to install additional packages afterwards.
129 </p>
130
131 <pre caption="Installing a minimal GNOME environment">
132 # <i>emerge gnome-light</i>
133 </pre>
134
135 <p>
136 This will take a while, so you might want to start reading all those books your
137 mother bought you but you never opened. Done? Great, now update your
138 environment variables:
139 </p>
140
141 <pre caption="Updating environment variables">
142 # <i>env-update &amp;&amp; source /etc/profile</i>
143 </pre>
144
145 <p>
146 Next we'll clean up the remaining services and user groups.
147 </p>
148
149 <pre caption="Setting up the DBUS service">
150 # <i>/etc/init.d/dbus start</i>
151 # <i>rc-update add dbus default</i>
152 </pre>
153
154 <p>
155 Check if the <e>plugdev</e> group exists. If it does, it is adviseable to make
156 yourself member of that group, but this is optional (the group is not that
157 common anymore).
158 </p>
159
160 <pre caption="Checking and adding users to plugdev">
161 ~# <i>getent group plugdev</i>
162 plugdev:x:104:
163
164 <comment># Substitute yourUserName with your user name ;-)</comment>
165 ~# <i>gpasswd -a yourUserName plugdev</i>

173
174 <p>
175 Let us first take a look at what we just built. Exit your root shell and log on
176 as a regular user. We will configure our session to run GNOME when we issue the
177 <c>startx</c> command (see also
178 <uri link="/doc/en/xorg-config.xml#using_startx">Using startx</uri> in the
179 <uri link="/doc/en/xorg-config.xml">X Server Configuration Howto</uri>):
180 </p>
181
182 <pre caption="Setting GNOME as the default desktop environment">
183 $ <i>echo "exec gnome-session" &gt; ~/.xinitrc</i>
184 </pre>
185
186 <p>
187 Starting with <c>gnome-base/gnome-session-2.26.2</c>, you will need to prepend
188 the XDG_MENU_PREFIX variable to get the Gnome menus if you're using the
189 <path>~/.xinitrc</path> method to start your desktop. (If you're not using
190 <path>~/.xinitrc</path>, it will be handled automatically for you; no additional
191 configuration is needed.)
192 </p>
193
194 <pre caption="Prepending XDG_MENU_PREFIX to ~/.xinitrc">
195 $ <i>sed -i '1i\export XDG_MENU_PREFIX=gnome-' ~/.xinitrc</i>
196 </pre>
197
198 <p>
199 Now start your graphical environment by running <c>startx</c>:
200 </p>
201
202 <pre caption="Starting GNOME">
203 $ <i>startx</i>
204 </pre>
205
206 <p>
207 If all goes well, you should be greeted by GNOME. Congratulations. Now let us
208 take a look at how you can configure GNOME to suit your needs.

217 <title>GNOME's Graphical Login Manager</title>
218 <body>
219
220 <p>
221 If you want the GNOME Display Manager (GDM) to run automatically when you boot
222 (so you can log on graphically), you must add the <c>xdm</c> init script to the
223 default runlevel:
224 </p>
225
226 <pre caption="Adding xdm to the default runlevel">
227 # <i>rc-update add xdm default</i>
228 </pre>
229
230 <p>
231 Now edit <path>/etc/conf.d/xdm</path> and alter the DISPLAYMANAGER variable.
232 </p>
233
234 <pre caption="Editing /etc/conf.d/xdm">
235 DISPLAYMANAGER="gdm"
236 </pre>
237
238 <p>
239 If you installed Gnome using the <c>gnome-light</c> package, you will need to
240 install <c>gdm</c> too (as it is not defined as part of the <c>gnome-light</c>
241 package).
242 </p>
243
244 <pre caption="Installing the gdm application">
245 # <i>emerge gdm</i>
246 </pre>
247
248 <p>
249 If you reboot now, the GNOME Display Manager will prompt you for your username
250 and password and will default to using GNOME as Desktop Environment (even though
251 you will have the option of selecting a different one of course, choosing from
252 those available in <path>/usr/share/xsessions/</path>). Thus, if you use GDM,
253 you don't need to edit <path>~/.xinitrc</path>.
