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>

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

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

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

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