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.

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

77 <title>What do you need?</title>
78 <body>
79
80 <p>
81 Before you start installing GNOME, you might want to edit your USE variables.
82 Make sure that <c>X</c>, <c>gtk</c>, and <c>gnome</c> are in your USE variable
83 listed in <path>/etc/make.conf</path>. If you want support for <c>hald</c>, the
84 hardware abstraction layer daemon add <c>hal</c> to your USE flags. The same
85 goes for <c>dbus</c>, a system message bus Gnome uses extensively. The
86 <c>avahi</c> USE flag brings DNS detection to GNOME (similiar to Rendevouz under
87 Mac OS X). If you don't want KDE support (the other big desktop environment),
88 remove <c>qt3</c>, <c>qt4</c>, <c>arts</c>, and <c>kde</c>.
89 </p>
90
91 <pre caption="Example USE in /etc/make.conf">
92 USE="-qt3 -qt4 -arts -kde X dbus gtk gnome hal avahi"
93 </pre>
94
95 <p>
96 You can add the <c>branding</c> USE flag to get a lovely Gentoo-branded
97 splashscreen instead of the default Gnome splashscreen:
98 </p>
99
100 <pre caption="Enabling Gentoo branding">
101 # <i>echo "gnome-base/gnome-session branding" &gt;&gt; /etc/portage/package.use</i>
102 </pre>
103
104 <p>
105 Once done, start installing GNOME by emerging <c>gnome</c>:
106 </p>
107
108 <pre caption="Installing GNOME">
109 # <i>emerge gnome</i>
110 </pre>
111
112 <p>
113 You can also opt for a minimal Gnome installation using <c>gnome-light</c>:
114 </p>
115
116 <pre caption="Installing a minimal GNOME environment">
117 # <i>emerge gnome-light</i>
118 </pre>
119
120 <p>
121 This will take a while, so you might want to start reading all those books your
122 mother bought you but you never opened. Done? Great, now update your
123 environment variables:
124 </p>
125
126 <pre caption="Updating environment variables">
127 # <i>env-update &amp;&amp; source /etc/profile</i>
128 </pre>
129
130 <p>
131 If you paid attention to the output of your previous <c>emerge</c> command,
132 you'll notice that it suggests using <c>gamin</c> to have nautilus and
133 gnome-vfs monitor file changes:
134 </p>
135
136 <pre caption="Installing gamin, a file alteration monitor">
137 # <i>emerge gamin</i>
138 </pre>
139
140 <impo>
141 If you are switching from <c>fam</c> (the old, deprecated file monitor) to
142 <c>gamin</c>, you will need to remove <c>famd</c> from all runlevels and then
143 unmerge it:
144 </impo>
145
146 <pre caption="Optional: switching to gamin from fam">
147 # <i>rc-update del famd</i>
148 # <i>emerge --unmerge app-admin/fam</i>
149 </pre>
150
151 <p>
152 Next we'll clean up the remaining services.
153 </p>
154
155 <pre caption="Adding hald and avahi-dnsconfd to the default runlevel">
156 # <i>/etc/init.d/hald start</i>
157 # <i>rc-update add hald default</i>
158
159 # <i>/etc/ininit.d/dbus start</i>
160 # <i>rc-update add dbus default</i>
161
162 # <i>/etc/init.d/avahi-dnsconfd start</i>
163 # <i>rc-update add avahi-dnsconfd default</i>

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

181 $ <i>echo "exec gnome-session" &gt; ~/.xinitrc</i>
182 </pre>
183
184 <p>
185 Now start your graphical environment by running <c>startx</c>:
186 </p>
187
188 <pre caption="Starting GNOME">
189 $ <i>startx</i>
190 </pre>
191
192 <p>
193 If all goes well, you should be greeted by GNOME. Congratulations. Now let us
194 take a look at how you can configure GNOME to suit your needs.

203 <title>GNOME's Graphical Login Manager</title>
204 <body>
205
206 <p>
207 If you want the GNOME Display Manager (GDM) to run automatically when you boot
208 (so you can log on graphically), you must add the <c>xdm</c> init script to the
209 default runlevel:
210 </p>
211
212 <pre caption="Adding xdm to the default runlevel">
213 # <i>rc-update add xdm default</i>
214 </pre>
215
216 <p>
217 Now edit <path>/etc/conf.d/xdm</path> and alter the DISPLAYMANAGER variable.
218 </p>
219
220 <pre caption="Editing /etc/conf.d/xdm">
221 DISPLAYMANAGER="gdm"
222 </pre>
223
224 <p>
225 If you reboot now, the GNOME Display Manager will prompt you for your username
226 and password and will default to using GNOME as Desktop Environment (even though
227 you will have the option of selecting a different one of course, choosing from
228 those available in <path>/usr/share/xsessions/</path>). Thus, if you use GDM,
229 you don't need to edit <path>~/.xinitrc</path>.
230 </p>
231
232 <p>
233 To use the functionality of <c>hald</c> just start <c>gnome-volume-manager</c>
234 and edit its preferences. Also, you'll need to add your user to the
235 <c>plugdev</c> group.
