34 <p>
35 Almost every ATI board is supported by <uri
36 link="http://www.freedesktop.org/Software/xorg">xorg-x11</uri>, at least for
37 the 2D accelerated features. The 3D support is provided either by <uri
38 link="http://dri.sf.net">the DRI project</uri>, which is already present inside
39 the xorg-x11, or by closed source drivers <uri
40 link="http://mirror.ati.com/support/drivers/linux/radeon-linux.html">
41 provided</uri> by ATI.

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

89 <title>I'm not using an x86. What are my options?</title>
90 <body>
91
92 <p>
93 You have almost the same x11 support on PPC or Alpha platform but you can't
94 use the ATI closed source drivers. That means that you can't use the r300 3d
95 features at all. If you have such a board and you want it supported by x11,
96 you should contact <uri link="http://www.ati.com">ATI</uri> and ask them to open
97 the specs. Recently the AMD64 closed source driver has been released. AMD64
98 users can use it as the x86 users.
99 </p>
100
101 <impo>
102 In order to enable the agpgart for certain AMD64 chip sets you have to disable
103 the K8 IOMMU support

109 <title>I have a laptop. Is my "mobility" ATI model supported?</title>
110 <body>
111
112 <p>
113 It should be but you may have a configuration issue due to the OEM PCI id that
114 such chips may have. In most cases you may have to write the configuration file
115 yourself or use the <c>xorgconfig</c>.

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

170 It is suggested the use of <c>xorgcfg</c>, <c>xorgconfig</c> or directly by
171 using the Xorg auto configuration option:

181 Desktop Documentation Resources</uri>.

183
184 <note>
185 Users of the ati-drivers can also use <c>fglrxconfig</c>.

188 <impo>
189 PPC users could use the <c>Xautoconf</c> stand alone configuration tool by
190 emerging the <c>Xautoconf</c> ebuild, but isn't required.
