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

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 |

I have an All-In-Wonder/Vivo board. Are the multimedia features supported?

</title>
|

<body>
|

|

<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.

<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.

|

<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.

<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.

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:

<note>

You can use <c>aticonfig</c> if you have installed the <c>ati-drivers</c>

package.

PPC users could use the <c>Xorgautoconfig</c> stand-alone configuration tool by
|
| 195 |
emerging the <c>Xorgautoconfig</c> ebuild, but isn't required.
