==Installation==
===How do I know fglrx is installed correctly?===
There are several ways to check if fglrx is loaded and running.
<br>1. Check your X.org or XFree86 log. You should see "DRI Initialization Successful."
# less /var/log/Xorg.0.log
or
# less /var/log/XFree86.0.log
2. Check glxinfo. You should see "direct" and not "indirect."
# glxinfo | grep direct
3. Check your kernel log. You should see fglrx messages near the bottom.
# dmesg
4. Check your modules. You should see fglrx loaded.
# lsmod | grep fglrx
*NOTE: [[Glxgears is not a Benchmark|glxgears]] is not a definite way of checking the installation of fglrx.

=== Is the rebooting really necessary? ===

No.

However, rebooting is the easiest method to ensure that the kernel module(s) from the old driver are unloaded and the fglrx module is loaded instead. If you don't want to reboot for some reason, you may manually shut down Xorg, unload any old "drm", "radeon" or "fglrx" modules and then start Xorg again.

==Kernel==
===Why does fglrx not work for my bleeding-edge kernel?===
The development process of the fglrx driver and the Linux kernel are not on the same level. The fglrx driver requires some special interactions with the kernel memory API and these tend to change between kernel versions.

There is also an 11-12 week cycle required to develop, validate and test each release of an ATI driver <ref>http://www.phoronix.com/scan.php?page=article&item=735&num=1</ref>. ATI will only look to support the latest kernel that is officially out (no -rc or -git releases are supported) at the time they release a driver. Example: fglrx version A comes out Monday, but kernel version B comes out Tuesday. Kernel version B is not supported by fglrx version A. (but might be able to work anyway by doing a 'modprobe -f fglrx' in a shell)

The binary part of ATI's kernel module has no explicit dependency on the Linux kernel. There are a set of source files that provide the glue to the kernel. This is where the dependency to different kernels exist. As a result, user contributed patches for newer kernels can often be found by searching [http://ati.cchtml.com Bugzilla].

==X Configuration==
===Composite Extension===
If you've enabled transparency, and you've added the Composite extension to the xorg.conf file, the ATI driver will disable DRI.

The only way to use 3D and the ATI OpenGL drivers is commenting the Option "Composite" "Enable" line.

It may be necessary to put the following lines into xorg.conf:

Section "Extensions"
Option "Composite" "Disable"
EndSection

ATI Linux fglrx driver version 8.39.4

Release Date: 7-23-2007

== Feature Wish List ==

The following features are still not supported properly by ATI's driver:

* Composite Extension: The ATI driver is far behind other open source Xorg drivers in supporting Composite extension. Clearly they are not keeping up and will benefit significantly by releasing their source code under GPL or BSD or MIT license.
* Removing the need to enable module support in the kernel to fully install the driver. It will work without it, but that doesn't enable DRI. This is possible by releasing their source code under the GPL license, and creating a patch for the kernel.
