36 <title>Is my AMD/ATI board supported?</title>

39 <p>
40 Many AMD/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 AMD's <uri
44 link="http://www.amd.com/us/products/technologies/ati-catalyst/Pages/catalyst.aspx">closed
45 source drivers</uri>. AMD's closed source driver only supports R600 and newer
46 GPUs. Older GPUs will use the mature open source xorg-x11 driver.

122 I have an All-In-Wonder/Vivo board. Are the multimedia features supported?
123 </title>
124 <body>
125
126 <p>
127 You don't need to use anything special for the board's multimedia features;
128 <c>x11-drivers/xf86-video-ati</c> will work just fine.

134 <title>I'm not using an x86-based architecture. What are my options?</title>
135 <body>
136
137 <p>
138 X11 support on the PPC or Alpha platforms is quite similar to x86 X11 support.
139 However, AMD/ATI's closed source Catalyst drivers are not supported on the PPC
140 or Alpha, so you will have to use the open source drivers. The Catalyst drivers
141 are only available for x86 and AMD64. The open source xorg-x11 drivers should
142 work well on all architectures.
143 </p>
144
145 <impo>
146 To enable agpgart support for certain old AMD64 chipsets, you have to disable
147 support for the K8 IOMMU.

153 <title>I have a laptop. Is my ATI Mobility model supported?</title>
154 <body>
155
156 <p>
157 It should be, but you may have a configuration issue due to the OEM PCI id that
158 such chips may have. In such cases, you may have to write the configuration
159 file yourself.

172 <p>
173 There are two ways of getting drivers for your AMD/ATI card:
174 </p>
175
176 <ul>
177 <li>The <c>xorg-x11</c> ebuild provides the X11 implementation</li>
178 <li>
179 The <c>ati-drivers</c> ebuild provides the AMD closed source X drivers
180 and kernel modules
181 </li>
182 </ul>
183
184 <p>
185 If you want to use AMD/ATI's <e>internal</e> agpgart support instead of the Linux
186 kernel one, the agpgart driver and the chip set specific driver (in your kernel
187 configuration) must be built as modules or not at all.
188 </p>
189
190 <note>
191 Please read the <uri link="/doc/en/dri-howto.xml">Hardware Acceleration
192 Guide</uri> for more information on installing drivers for your AMD/ATI graphics
193 card.

199 <title>Configuration</title>
200 <body>
201
202 <p>
203 You may not need to manually create <path>xorg.conf</path> or modify it if you
204 are using the open-source radeon driver. Try running without it first. If this
205 fails, you can use the auto-configuration option of X:
206 </p>
207
208 <pre caption="Autoconfiguring X">
209 # <i>X -configure</i>
210 </pre>
211
212 <p>
213 If you use the proprietary ATI drivers, you can get assistance for configuring
214 X through the <c>aticonfig</c> application (which is part of the
215 <c>ati-drivers</c> package).
216 </p>
217
218 <p>
219 For more information on how to get a basic <c>xorg.conf</c> configuration file,
220 please refer to the <uri link="/doc/en/xorg-config.xml">Gentoo X Server
221 HowTo</uri>.
222 </p>
223
224 <note>
225 PPC, AMD64, and x86 users can use the <c>xac</c> stand-alone X configuration
226 tool by emerging <c>x11-misc/xac</c>, but isn't required.
227 </note>
228
229 <impo>
230 If you're using <c>ati-drivers</c>, then you'll need to disable <c>radeonfb</c>
231 (and probably any other framebuffer drivers) in your kernel config, as it
232 conflicts with the built-in framebuffer in <c>ati-drivers</c>.

240
241 <p>
242 Once X is installed, configured, and running, it can use the AMD/ATI OpenGL
243 libraries:
