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.

108 The <uri link="http://www.x.org/wiki/RadeonFeature">Radeon Feature Matrix</uri>
109 at x.org lists the open source driver support level for each part of the
110 graphics card hardware.

117 I have an All-In-Wonder/Vivo board. Are the multimedia features supported?
118 </title>
119 <body>
120
121 <p>
122 You don't need to use anything special for the board's multimedia features;
123 <c>x11-drivers/xf86-video-ati</c> will work just fine.

129 <title>I'm not using an x86-based architecture. What are my options?</title>
130 <body>
131
132 <p>
133 X11 support on the PPC or Alpha platforms is quite similar to x86 X11 support.
134 However, AMD/ATI's closed source Catalyst drivers are not supported on the PPC
135 or Alpha, so you will have to use the open source drivers. The Catalyst drivers
136 are only available for x86 and AMD64. The open source xorg-x11 drivers should
137 work well on all architectures.
138 </p>
139
140 <impo>
141 To enable agpgart support for certain old AMD64 chipsets, you have to disable
142 support for the K8 IOMMU.

148 <title>I have a laptop. Is my ATI Mobility model supported?</title>
149 <body>
150
151 <p>
152 It should be, but you may have a configuration issue due to the OEM PCI id that
153 such chips may have. In such cases, you may have to write the configuration
154 file yourself.

167 <p>
168 There are two ways of getting drivers for your AMD/ATI card:
169 </p>
170
171 <ul>
172 <li>The <c>xorg-x11</c> ebuild provides the X11 implementation</li>
173 <li>
174 The <c>ati-drivers</c> ebuild provides the AMD closed source X drivers
175 and kernel modules
176 </li>
177 </ul>
178
179 <p>
180 If you want to use AMD/ATI's <e>internal</e> agpgart support instead of the Linux
181 kernel one, the agpgart driver and the chip set specific driver (in your kernel
182 configuration) must be built as modules or not at all.
183 </p>
184
185 <note>
186 Please read the <uri link="/doc/en/dri-howto.xml">Hardware Acceleration
187 Guide</uri> for more information on installing drivers for your AMD/ATI graphics
188 card.

194 <title>Configuration</title>
195 <body>
196
197 <p>
198 You may not need to manually create <path>xorg.conf</path> or modify it. Try
199 running without it first. You can also use the Xorg auto configuration option:
200 </p>
201
202 <pre caption="Autoconfiguring X">
203 # <i>X -configure</i>
204 </pre>
205
206 <p>
207 For more information on how to get a basic <c>xorg.conf</c> configuration file,
208 please refer to the <uri link="/doc/en/xorg-config.xml">Gentoo X Server
209 HowTo</uri>.
210 </p>
211
212 <note>
213 PPC, AMD64, and x86 users can use the <c>xac</c> stand-alone X configuration
214 tool by emerging <c>x11-misc/xac</c>, but isn't required.
215 </note>
216
217 <note>
218 You can use <c>aticonfig</c> if you have installed the <c>ati-drivers</c>
219 package.
220 </note>
221
222 <impo>
223 If you're using <c>ati-drivers</c>, then you'll need to disable <c>radeonfb</c>
224 (and probably any other framebuffer drivers) in your kernel config, as it
225 conflicts with the built-in framebuffer in <c>ati-drivers</c>.

235 Once X is installed, configured, and running, it can use the AMD/ATI OpenGL
236 libraries:
