=== No 3D acceleration ===
If you see output that looks like this:

 $ fglrxinfo 
 display: :0.0 screen: 0 
 OpenGL vendor string: Mesa project: www.mesa3d.org 
 OpenGL renderer string: Mesa GLX Indirect 
 OpenGL version string: 1.2 (1.5 Mesa 6.4.1) 

Then try these two commands:

 mkdir -p /usr/X11R6/lib/modules/dri 
 ln -s /usr/lib/dri/fglrx_dri.so /usr/X11R6/lib/modules/dri

=== System lockup on logout or switch to virtual consoles ===

If your system locks up after you logout or when you try to switch to a virtual console, this might be an instance of [http://ati.cchtml.com/show_bug.cgi?id=330 this bug]. It is likely that the problem only occurs for users with an '''Xorg version of at least 7.0''' and an '''amd64''' system. Probably it only affects users of '''DVI'''.

There is a workaround: Use a standard D-Sub VGA connector instead of the DVI connector.

This workaround was posted as a comment to another related bug: see [http://ati.cchtml.com/show_bug.cgi?id=239#c48 here].


=== X800/X850 fan is very loud / constantly works ===

It seems fglrx has a bug with all X800/X850 cards causing them to heat up excessively
even when not in 3D mode. This behaviour will cause the cards' fans to function on full
blast continuously. There is no known fix as of driver 8.31.05 or previous. Open source
"radeon" driver does not exhibit this problem.



=== nForce 3 AGP Issues ===

For nForce3 based motherboards: if the install seems to go well, but fglrx still fails and $ fglrxinfo tells you you're still running Mesa, there may be a problem with the nVidia AGP-PCI Bridge module's compatibility with your BIOS (or vice versa, I haven't yet investigated). (Confirmed at least for ASUS K8N-E Deluxe.) A solution is to downgrade your BIOS to a previous version (see your motherboard manual/manufacturer's website for instructions). Here is a list of compatible BIOS versions (if your model is not listed here and you find a version that fixes the problem, please add it to the list so others can benefit):

*ASUS
**K8N-E Deluxe: Version 1006
**K8N Bios versions up 1003 to 1011, my Solution -> K8V-X (Asus with Via-Chipset) It is working really good now. (Always Problems: nForce3 Chipset)

*ASROCK
**K8Upgrade-NF3
(A little workaround for K8Upgrade-NF3 is to edit xorg.conf, in section "Devices", adding this line: Option "UseInternalAGPGART" "no")

=== Graphical Anomalies ===

This was experienced with an ATI Radeon X1600 Pro 512mb:

After following instructions for both Method 1 and Method 2, whenever I disabled the Composite Extension, the display would be almost unusable, but the fglrxinfo command would display the correct information.  If I re-enabled the Composite Extension the display would be usable, but fglrxinfo would report using mesa drivers.

To resolve the problem I needed to lower the AGP Aperture setting in my BIOS to 128mb (or lower worked too).  The AGP Aperture was initially set to 256mb. After setting the AGP Aperture to 128mb, everything worked perfectly; the Composite Extension is disabled, fglrxinfo reports the correct drivers, and direct rendering is enabled. Some systems may require setting the AGP Aperture to the highest setting (256mb or 512mb).

Yet another user of the same type card (Sapphire Brand) also reports that after alot of headaches that this did the trick for him also.
