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

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

60 Like with any big free software project, GNOME has an extensive user- and
61 development base. <uri link="http://www.gnomedesktop.org">Footnotes</uri>
62 contains GNOME Desktop news for users; <uri
63 link="http://planet.gnome.org">GnomePlanet</uri> is for hackers/contributors and
64 <uri link="http://developer.gnome.org">Developer.Gnome.Org</uri> is for the
65 GNOME developers.

73 <section>
74 <title>What do you need?</title>
75 <body>
76
77 <p>
78 Before you start installing GNOME, you might want to edit your USE variables.
79 Make sure that <c>gtk</c> and <c>gnome</c> are in your USE variable listed in
80 <path>/etc/make.conf</path>. If you want support for <c>hald</c>, the hardware
81 abstraction layer daemon add <c>hal</c> to your USE flags. USE variable
82 <c>avahi</c> brings DNS-detection to GNOME (similiar to Rendevouz under Mac OS
83 X). If you don't want KDE support (the other big desktop environment), remove
84 <c>qt*</c>, <c>arts</c> and <c>kde</c>.
85 </p>
86
87 <pre caption="Example USE in /etc/make.conf">
88 USE="-qt3 -qt4 -arts -kde gtk gnome hal avahi"
89 </pre>
90
91 <p>
92 You can add the <c>branding</c> USE flag to get a lovely Gentoo-branded
93 splashscreen instead of the default Gnome splashscreen:
94 </p>
95
96 <pre caption="Enabling Gentoo branding">
97 # <i>echo "gnome-base/gnome-session branding" &gt;&gt; /etc/portage/package.use</i>
98 </pre>
99
100 <p>
101 Once done, start installing GNOME by emerging <c>gnome</c>:
102 </p>
103
104 <pre caption="Installing GNOME">
105 # <i>emerge gnome</i>
106 </pre>
107
108 <p>
109 You can also opt for a minimal Gnome installation using <c>gnome-light</c>:
110 </p>
111
112 <pre caption="Installing a minimal GNOME environment">
113 # <i>emerge gnome-light</i>
114 </pre>
115
116 <p>
117 This will take a while, so you might want to start reading all those books your
118 mother bought you but you never opened. Done? Great, now update your
119 environment variables:
120 </p>
121
122 <pre caption="Updating environment variables">
123 # <i>env-update &amp;&amp; source /etc/profile</i>
124 </pre>
125
126 <p>
127 If you paid attention to the output of your previous <c>emerge</c> command,
128 you'll notice that it suggests using <c>gamin</c> to have nautilus and
129 gnome-vfs monitor file changes:
130 </p>
131
132 <pre caption="Installing gamin, a file alteration monitor">
133 # <i>emerge gamin</i>
134 </pre>
135
136 <impo>
137 If you are switching from <c>fam</c> (the old, deprecated file monitor) to
138 <c>gamin</c>, you will need to remove <c>famd</c> from all runlevels and then
139 unmerge it:
140 </impo>
141
142 <pre caption="Optional: switching to gamin from fam">
143 # <i>rc-update del famd</i>
144 # <i>emerge --unmerge app-admin/fam</i>
145 </pre>
146
147 <p>
148 Next we'll clean up the remaining services.
149 </p>
150
151 <pre caption="Adding hald and avahi-dnsconfd to the default runlevel">
152 # <i>/etc/init.d/hald start</i>
153 # <i>rc-update add hald default</i>
154
155 # <i>/etc/init.d/avahi-dnsconfd start</i>
156 # <i>rc-update add avahi-dnsconfd default</i>

165 <p>
166 Let us first take a look at what we just built. Exit your root shell and log on
167 as a regular user. We will configure our session to run GNOME when we issue the
168 <c>startx</c> command (see also
169 <uri link="/doc/en/xorg-config.xml#using_startx">Using startx</uri> in the
170 <uri link="/doc/en/xorg-config.xml">X Server Configuration Howto</uri>):
171 </p>

173 <pre caption="Having GNOME as default desktop environment">
174 $ <i>echo "exec gnome-session" &gt; ~/.xinitrc</i>
175 </pre>
176
177 <p>
178 Now start your graphical environment by running <c>startx</c>:
179 </p>
180
181 <pre caption="Starting GNOME">
182 $ <i>startx</i>
183 </pre>
184
185 <p>
186 If all goes well, you should be greeted by GNOME. Congratulations. Now let us
187 take a look at how you can configure GNOME to suit your needs.

196 <title>GNOME's Graphical Login Manager</title>
197 <body>
198
199 <p>
200 If you want the GNOME Display Manager (GDM) to run automatically when you boot
201 (so you can log on graphically), you must add the <c>xdm</c> init script to the
202 default runlevel:
203 </p>
204
205 <pre caption="Adding xdm to the default runlevel">
206 # <i>rc-update add xdm default</i>
207 </pre>
208
209 <p>
210 Now edit <path>/etc/conf.d/xdm</path> and alter the DISPLAYMANAGER variable.
211 </p>
212
213 <pre caption="Editing /etc/conf.d/xdm">
214 DISPLAYMANAGER="gdm"
215 </pre>
216
217 <p>
218 If you reboot now, the GNOME Display Manager will prompt you for your username
219 and password and will default to using GNOME as Desktop Environment (even though
220 you will have the option of selecting a different one of course, choosing from
221 those available in <path>/usr/share/xsessions/</path>). Thus, if you use GDM,
222 you don't need to edit <path>~/.xinitrc</path>.
223 </p>
224
225 <p>
226 To use the functionality of <c>hald</c> just start <c>gnome-volume-manager</c>
227 and edit its preferences. Also, you'll need to add your user to the
228 <c>plugdev</c> group.
