Run the following command to check its output to ensure the fglrx driver is installed properly:
64bit Users only ( 32bit users can continue to the fglrxinfo test ), after rebooting you may have noticed that you cant open aticonfig and the fglrxinfo test below may not show ati in the info from the test, to fix this in terminal do the following command
sudo ln -s /usr/lib/libGL.so.1.2 /usr/lib/libGL.so.1
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI MOBILITY RADEON X300
OpenGL version string: 2.1.7415 Release
The <code>OpenGL vendor string</code> should read '''ATI''' and not '''Mesa'''.
'''If it still says ''Mesa'' and not ''ATI'', even after re-enabling the driver from the Restricted-manager:'''
You can try the following:
:*<pre>$ less /var/log/Xorg.0.log |grep EE</pre> if this command returns <code>(EE) fglrx(0): incompatible kernel module detected - HW accelerated OpenGL will not work</code> then remove the kernel module and reinstall it.
:: <pre>$ sudo dkms remove -m fglrx -v 8.471 --all</pre>
:*Remove all the packages provided by the <code>xserver-xorg-video-all</code> meta-package (search for it using Synaptic or Adept), then restart the machine. The X Server should now use the new fglrx driver by force (provided the driver is being used in ''xorg.conf'').
::If you can't log in after this, you'll have to log in to a terminal in the login screen, and reinstall the <code>xserver-xorg-video-all</code> package. Your problem is probably somewhere else. (taken from [http://ubuntuforums.org/showpost.php?p=3655658&postcount=139]).
:*Remove the package xserver-xgl.
::'''Explanation:''' If you installed this previously in order to make compiz work, it will not allow direct rendering on your display. You can check out if this is what it causing the problem by running

Note: Here is the [[glxinfo]] of a good install (for those interested).
=== Enable laptop mode on battery power ===
Enabling laptop mode on battery power gives you much better battery life, however be aware that sometimes it causes odd hangs.
Switch ENABLE_LAPTOP_MODE to true 
{{Box File|/etc/default/acpi-support|
# Switch to laptop-mode on battery power - off by default as it causes odd
# hangs on some machines
{{Box File|/etc/default/fglrx|
# Uncomment the next line to enable powerstate switching on ACPI
# events for lid open/close and AC adapter on/off
=== Additional configure with aticonfig tool ===
You can configure the driver even further with the '''aticonfig''' tool, more information can be found at [[Configuring]].
For example: <br>
* use powerplay option to switch power state for battery friendly or performance mode
* use dual head or one big desktop mode
* turn second monitor on/off on the fly

Specific Issues

3D desktop effects

The new ATI drivers use AIGLX so there is not need to install XGL that older drivers (< 8.40) required.

Remove this section from to the /etc/X11/xorg.conf file. The new xorg server enables "Composite" by default.

# Section "Extensions"
#        Option  "Composite" "0"
# EndSection

Compiz does not know about the fglrx driver. You can either skip the checks

mkdir -p ~/.config/compiz && echo SKIP_CHECKS=yes >> ~/.config/compiz/compiz-manager

or add it to the compiz white list, and clear the blacklist pci Ids variable *Recommended*

sudo gedit /usr/bin/compiz
# Driver whitelist
WHITELIST="fglrx nvidia intel ati radeon i810"
# blacklist based on the pci ids 

You might have to modify the path for line 30 and 31

   COMPIZ_BIN_PATH="/usr/bin/" # For window decorators and compiz

The COMPIZ_NAME on line 35 should also be modified accordingly

   COMPIZ_NAME="compiz.real" # Final name for compiz (compiz.real) 

After the necessary configurations, just restart X and enjoy the cool effects.

If it still does not work, locate /etc/xdg/compiz/compiz-manager.ubuntu [this line may instead be in /etc/xdg/compiz/compiz-manager] and see if it contains an infinite loop in it. If it does, comment out the line that causes the infinite loop.

# . /etc/xdg/compiz/compiz-manager.ubuntu

For Kubuntu you need some extra steps:

sudo apt-get install compiz compiz-kde compizconfig-settings-manager compiz-core compiz-fusion-plugins-main compiz-plugins

To test 3D Effects, press ALT+F2 and type "compiz --replace".

To configure use the tool KMenu->Settings->Avanced Desktop Effect Settings.

Suspend/Hibernation work with 7.12

With Gutsy release, there was a big problem using the ATI proprietary drivers. The Suspend/Hibernate function stopped working. The problem was due to the new SLUB allocator incorporated in 2.6.22 / 2.6.23 Kernel.

The problem has been solved in the AMD Catalyst 7.12 driver release. UPDATE: The problem has NOT been solved in the AMD Catalyst 7.12 driver release.

Suspend/hibernate is not working for FireGL 5250. For FireGL 5200, suspend works with the 7.12 fglrx kernel module loaded (which did not work before this release) , but does not work if X is running.

For Thinkpad T60 with ATI X1400, to get the laptop to wake up from suspend, I had to change the following in /etc/default/acpi-support:



Even with the above settings (like POST_VIDEO=false, etc.) my ASUS Z96J with an X1600 does not suspend.

This bug has been a serious issue for several months now. There is a lot of frustration over this, because Ubuntu/Canonical has not been helpful. They've said things like suggesting not using fglrx (thanks a lot, that really helps).

Current status on this bug can be found here: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/121653/

If you get /usr/X11R6/lib/modules/dri/fglrx_dri.so not found

sudo ln -s /usr/lib/ /usr/X11R6/lib/modules

If you get /usr/X11R6/lib64/modules/dri/fglrx_dri.so not found

sudo ln -s /usr/lib/ /usr/X11R6/lib64/modules

Segmentation Fault with glxinfo/fglrxinfo

If fglrxinfo or glxinfo returns a Segmentation fault like this:

$ fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon Xpress Series
OpenGL version string: 1.4 (2.1.7170 Release)

Segmentation fault

Set output of libGL to verbose with

$ export LIBGL_DEBUG=verbose

Run fglrxinfo or glxinfo again

libGL: XF86DRIGetClientDriverName: 8.44.3 fglrx (screen 0)
libGL: OpenDriver: trying /usr/lib/dri/fglrx_dri.so
libGL error: dlopen /usr/lib/dri/fglrx_dri.so failed (/usr/lib/dri/fglrx_dri.so: cannot open shared object file: Permission denied)
libGL error: unable to load driver: fglrx_dri.so
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon Xpress Series
OpenGL version string: 1.4 (2.1.7170 Release)

Segmentation fault

Don't know if its always fglrx_dri.so, but the fix is to add read permissions to the file.

Check if read permission is not there

ls -l /usr/lib/dri/ |grep fglrx_dri
-rw-rw---- 1 root root 17462688 2008-01-13 17:42 fglrx_dri.so

Add read permission

$ sudo chmod +r /usr/lib/dri/fglrx_dri.so

Check read permission

ls -l /usr/lib/dri/ |grep fglrx_dri
-rw-rw-r-- 1 root root 17462688 2008-01-13 17:42 fglrx_dri.so

libGL error

  • fglrxinfo gives: libGL.so.1: cannot open shared object file.
  • Check the permission of the libGL.so.1.2 file with command:
 ls -l /usr/lib/libGL*
  • The file permission of libGL.so.1.2 should be "-rw-rw-r--". If the permission reads "-rw-rw----", do command
 sudo chmod o+r /usr/lib/libGL.so.1.2
  • If the permission is correct, fixed with command:
sudo ln -s /usr/lib/libGL.so.1.2 /usr/lib/libGL.so.1

Monitor detection (1680x1050 Resolution Issue)--- SOLVED

As specified in the release notes, "Connecting a display device that supports 1680x1050 to a system running Linux may result in a maximum display resolution of 1280x1024 only being available". (from thread)

[It works with the latest driver]

Fglrx driver does not detect some monitors correctly, so you have to do it manually (google about your monitor spec with keyword: xorg.conf).

For example: Samsung 205BW 1680x1050 monitor needs manually set:

File: /etc/X11/xorg.conf
Section "Monitor"
       Option "DPMS"
       Identifier "samsung-monitor"
       VendorName "Samsung"
       ModelName "SyncMaster 205BW"
       HorizSync 31.4 - 80.0
       VertRefresh 56.000 - 75.000
       Modeline "1680x1050" 146.25 1680 1784 1960 2240 1050 1053 1059 1089

Section "Screen"
	Identifier	"samsung-screen"
	Device		"samsung-device"
	Monitor		"samsung-monitor"
	Defaultdepth	24
	SubSection "Display"
		Depth	24
		Modes		"1680x1050"

A possible problem with fglrx.ko conflicts

NOTE: I've run into strange problem building fglrx-kernel-source_8.443.1-1_i386.deb. If pentium-builder is installed, dkms fails to build fglrx.ko for make error (mixed implicit and static pattern rules. Stop.). It is caused by gcc.real and other indirections and wrong gcc version detection. Removing pentium-builder cures the problem.

It's necessary, because sometimes this file is written by other packages, and so there's no 3D acceleration. Check that the file /lib/modules/$(uname -r)/misc/fglrx.ko has been created.

Create the following folder

sudo mkdir /lib/modules/$(uname -r)/volatile

Note: the volatile directory might already exist at this stage then simply continue with the next step.

Create a symbolic link

sudo ln -sf /lib/modules/$(uname -r)/misc/fglrx.ko /lib/modules/$(uname -r)/volatile/fglrx.ko

NOTE : On my Gutsy install, after a reboot this link was always removed automatically leaving me without an fglrx module loaded, and thus no ATI rendering. There have been several ways of getting around this suggested here, and here is the one that worked for me:

sudo gedit /etc/init.d/ati-module-fix

And put this in it:

#!/bin/sh -e

# For loading ATI display drivers

ln -sf /lib/modules/$(uname -r)/misc/fglrx.ko /lib/modules/$(uname -r)/volatile/fglrx.ko
exit 0

Make it executable

sudo chmod ugo+x /etc/init.d/ati-module-fix

Now, make this run before gdm

To check the gdm sequence number,

ls /etc/rc2.d/

The value for [seqno] in the section below should be the gdm sequence number -1.

sudo update-rc.d ati-module-fix defaults [seqno]

Hang at logout

If you experience hangs when logging out (of X) try disabling atieventsd with this command:

sudo /usr/sbin/update-rc.d -f atieventsd remove

Revert to Xorg driver

If (for any reason) the fglrx install fails, you can revert to the Xorg driver by executing

sudo dpkg-reconfigure xserver-xorg

and selecting the "ati" driver, or simply restoring the previous /etc/X11/xorg.conf file, if you made a backup.

You also need to remove the xorg-driver-fglrx or your manually installed drivers to get the 3D acceleration back, since it is provided by file /usr/lib/libGL.so.1.2 which belongs to libgl1-mesa package and which is moved to backup and replaced at the installation of xorg-driver-fglrx (or the manually built) package. In case the removal of the fglrx drivers fails to restore the file from libgl1-mesa, you have to reinstall the package by running:

sudo apt-get install --reinstall libgl1-mesa-glx
