36 <title>Is my ATI board supported?</title>
37 <body>

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 xorg-x11 driver.

101 I have an All-In-Wonder/Vivo board. Are the multimedia features supported?
102 </title>
103 <body>
104
105 <p>
106 The board's multimedia features are supported by <uri
107 link="http://gatos.sf.net">the GATOS project</uri>. These drivers have been
108 merged into the Xorg tree. You don't need to use anything special;
109 <c>x11-drivers/xf86-video-ati</c> will work just fine.
110 </p>

115 <title>I'm not using an x86-based architecture. What are my options?</title>
116 <body>
117
118 <p>
119 X11 support on the PPC or Alpha platforms is quite similar to x86 X11 support.
120 However, ATI's closed source drivers are not supported on the PPC or Alpha, so
121 you cannot use the 3D features of the R300 Graphics Processing Unit (GPU). If
122 you have such a board and want it supported by X11, contact <uri
123 link="http://www.ati.com">ATI</uri> and ask them to release the specifications
124 for your system's GPU. The closed source driver for the AMD64 was released, so
125 AMD64 users can now enjoy the same features as x86 users.
126 </p>
127
128 <impo>
129 To enable agpgart support for certain AMD64 chip sets, you have to disable
130 support for the K8 IOMMU.

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

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

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

223 Once X is installed, configured, and running, it can use the ATI OpenGL
224 libraries:
