19 This FAQ should help users avoid some common installation and configuration
20 issues related to DRI and X11 for ATI boards.

33 <title>Is my ATI board supported?</title>
34 <body>

36 <p>
37 Many ATI boards (but not all) are supported by <uri
38 link="http://www.freedesktop.org/Software/xorg">xorg-x11</uri>, at least for
39 the 2D accelerated features. The 3D support is provided either by <uri
40 link="http://dri.sf.net">the DRI project</uri> which is part of xorg-x11, or by
41 ATI's <uri
42 link="http://mirror.ati.com/support/drivers/linux/radeon-linux.html">closed
43 source drivers</uri>.

78 I have an All-In-Wonder/Vivo board. Are the multimedia features supported?
79 </title>
80 <body>
81
82 <p>
83 The board's multimedia features are supported by <uri
84 link="http://gatos.sf.net">the GATOS project</uri>. These drivers will be
85 merged into the xorg tree shortly.

91 <title>I'm not using an x86-based architecture. What are my options?</title>
92 <body>
93
94 <p>
95 X11 support on the PPC or Alpha platforms is quite similar to x86 X11 support.
96 However, ATI's closed source drivers are not supported on the PPC or Alpha, so
97 you cannot use the 3D features of the R300 Graphics Processing Unit (GPU). If
98 you have such a board and want it supported by X11, contact <uri
99 link="http://www.ati.com">ATI</uri> and ask them to release the specifications
100 for your system's GPU. The closed source driver for the AMD64 was released, so
101 AMD64 users can now enjoy the same features as x86 users.
102 </p>
103
104 <impo>
105 To enable agpgart support for certain AMD64 chip sets, you have to disable
106 support for the K8 IOMMU.

112 <title>I have a laptop. Is my ATI Mobility model supported?</title>
113 <body>
114
115 <p>
116 It should be, but you may have a configuration issue due to the OEM PCI id that
117 such chips may have. In most cases, you may have to write the configuration
118 file yourself or use the <c>xorgconfig</c> utility.

131 <ul>
132 <li>The <c>xorg-x11</c> ebuild provides the X11 implementation</li>
133 <li>
134 For a 2.6.x kernel the DRI modules can be built with the kernel or be
135 provided by the <c>x11-drm</c> ebuild
136 </li>
137 <li>For a 2.4.x kernel series you must use the <c>x11-drm</c> ebuild</li>
138 <li>
139 The <c>ati-drivers</c> ebuild provides the ATI closed source X drivers and
140 kernel modules, for both the 2.4 and 2.6 series kernels
141 </li>
142 </ul>
143
144 <p>
145 If you want to use ATI's <e>internal</e> agpgart support instead of the Linux
146 kernel one, the agpgart driver and the chip set specific driver (in your kernel
147 configuration) must be built as modules or not at all.

172 <p>
173 The use of <c>xorgcfg</c> or <c>xorgconfig</c> to generate the
174 <path>xorg.conf</path> configuration file is suggested. Alternatively, you may
175 use the Xorg auto configuration option:

183 For more information on how to get a basic <c>xorg.conf</c> configuration file,
184 please refer to the <uri link="/doc/en/xorg-config.xml">Gentoo X Server
185 HowTo</uri>.
186 </p>
187
188 <note>
189 You can use <c>aticonfig</c> if you have installed the <c>ati-drivers</c>
190 package.
191 </note>
192
193 <impo>
194 PPC users could use the <c>Xorgautoconfig</c> stand-alone configuration tool by
195 emerging the <c>Xorgautoconfig</c> ebuild, but isn't required.
