39 <p>
40 Many ATI boards (but not all) are supported by <uri
41 link="http://www.freedesktop.org/Software/xorg">xorg-x11</uri>, at least for the
42 2D accelerated features. The 3D support is provided either by xorg-x11, or by
43 ATI's <uri
44 link="http://mirror.ati.com/support/drivers/linux/radeon-linux.html">closed
45 source drivers</uri>. ATI's closed source driver only supports R600 and newer
46 GPUs. Older GPUs will use the mature open source xorg-x11 driver.

106 I have an All-In-Wonder/Vivo board. Are the multimedia features supported?
107 </title>
108 <body>
109
110 <p>
111 You don't need to use anything special for the board's multimedia features;
112 <c>x11-drivers/xf86-video-ati</c> will work just fine.

118 <title>I'm not using an x86-based architecture. What are my options?</title>
119 <body>
120
121 <p>
122 X11 support on the PPC or Alpha platforms is quite similar to x86 X11 support.
123 However, ATI's closed source Catalyst drivers are not supported on the PPC or
124 Alpha, so you will have to use the open source drivers. The Catalyst drivers are
125 only available for x86 and AMD64. The open source xorg-x11 drivers should work
126 well on all architectures.
127 </p>
128
129 <impo>
130 To enable agpgart support for certain old AMD64 chipsets, you have to disable
131 support for the K8 IOMMU.

137 <title>I have a laptop. Is my ATI Mobility model supported?</title>
138 <body>
139
140 <p>
141 It should be, but you may have a configuration issue due to the OEM PCI id that
142 such chips may have. In such cases, you may have to write the configuration
143 file yourself.

156 <p>
157 There are two ways of getting drivers for your ATI card:
158 </p>
159
160 <ul>
161 <li>The <c>xorg-x11</c> ebuild provides the X11 implementation</li>
162 <li>
163 The <c>ati-drivers</c> ebuild provides the ATI closed source X drivers and
164 kernel modules
165 </li>
166 </ul>
167
168 <p>
169 If you want to use ATI's <e>internal</e> agpgart support instead of the Linux
170 kernel one, the agpgart driver and the chip set specific driver (in your kernel
171 configuration) must be built as modules or not at all.
172 </p>
173
174 <note>
175 Please read the <uri link="/doc/en/dri-howto.xml">Hardware Acceleration
176 Guide</uri> for more information on installing drivers for your ATI graphics
177 card.

183 <title>Configuration</title>
184 <body>
185
186 <p>
187 You may not need to manually create <path>xorg.conf</path> or modify it. Try
188 running without it first. You can also use the Xorg auto configuration option:
189 </p>
190
191 <pre caption="Autoconfiguring X">
192 # <i>X -configure</i>
193 </pre>
194
195 <p>
196 For more information on how to get a basic <c>xorg.conf</c> configuration file,
197 please refer to the <uri link="/doc/en/xorg-config.xml">Gentoo X Server
198 HowTo</uri>.
199 </p>
200
201 <note>
202 PPC, AMD64, and x86 users can use the <c>xac</c> stand-alone X configuration
203 tool by emerging <c>x11-misc/xac</c>, but isn't required.
204 </note>
205
206 <note>
207 You can use <c>aticonfig</c> if you have installed the <c>ati-drivers</c>
208 package.
209 </note>
210
211 <impo>
212 If you're using <c>ati-drivers</c>, then you'll need to disable <c>radeonfb</c>
213 (and probably any other framebuffer drivers) in your kernel config, as it
214 conflicts with the built-in framebuffer in <c>ati-drivers</c>.
215 </impo>

222
223 <p>
224 Once X is installed, configured, and running, it can use the ATI OpenGL
225 libraries:
