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

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

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

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

132 <ul>
133 <li>The <c>xorg-x11</c> ebuild provides the X11 implementation</li>
134 <li>
135 For a 2.6.x kernel the DRI modules can be built with the kernel or be
136 provided by the <c>x11-drm</c> ebuild
137 </li>
138 <li>
139 For a 2.4.x kernel series you must use the <c>x11-drm</c> ebuild
140 </li>
141 <li>
142 The <c>ati-drivers</c> ebuild provides the ATI closed source X drivers
143 and kernel modules, for both the 2.4 and 2.6 series kernels
144 </li>
145 </ul>
146
147 <p>
148 If you want to use ATI's <e>internal</e> agpgart support instead of the Linux
149 kernel one, the agpgart driver and the chip set specific driver (in your kernel
150 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
175 may 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/index.xml?catid=desktop">Gentoo
185 Desktop Documentation Resources</uri>.
186 </p>
187
188 <note>
189 You can use <c>fglrxconfig</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.
