Ubuntu Saucy Installation Guide

= The Options = Users with ATI cards have the following driver options:
 * vesa - very basic, lacks 2D/3D acceleration, and focuses on compatibility with all VESA-compliant graphics cards. It is good for starting the GUI environment when no accelerated driver is available/working, and little else.
 * ati - actually a thin wrapper that will invoke the radeon driver (or another ati open-source driver for pre-Radeon cards).
 * radeon - open source driver supporting all Radeon cards. This driver has excellent 2D acceleration and compatibility with the Linux graphics stack. 3D acceleration is sufficient for desktop effects and a nice set of native Linux games.
 * Catalyst (a.k.a fglrx) a proprietary "blob" (closed source binary) driver designed by ATI, with 3D code based off of their Windows driver. Only RadeonHD chips are supported on recent Linux distros. You may want to use this driver for longer battery life on a laptop or for more demanding 3D applications.

= Updated Open Source Driver PPA's =
 * "Ubuntu-X" : This PPA offers the latest stable releases of video driver-related components. Follow the instructions at: https://launchpad.net/~ubuntu-x-swat/+archive/x-updates
 * Xorg-edgers: This bleeding-edge PPA offers video driver-related components straight from their code (git) repositories. Follow the instructions at: https://launchpad.net/~xorg-edgers/+archive/ppa

= Installing Proprietary Drivers a.k.a. Catalyst/fglrx =

ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300 If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later). If you really need the proprietary Catalyst/fglrx driver, you will have to use an older Linux distribution, such as Debian Lenny/5.0.x or Ubuntu Hardy/8.04.x. NOTE: If you enter your card information on AMD/ATI's driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn't support X servers past 1.5, and it will not work with Precise (or anything later than Lucid/10,04)! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the 'Removing the Driver' section to restore the default/pre-installed drivers.

ATI RadeonHD 2x00 - 4xx0 cards If you have one of these cards, you do have the option of using the Catalyst Legacy driver, but only if you downgrade your Xserver version (the Catalyst Legacy driver does not support the kernel version (3.5) or the Xserver version (1.13) that Ubuntu Quantal/12.10 uses). This can be done really easily and automaticly (downgrading & installing) by following the instructions given at []. This PPA downgrades the Xserver and install a patched version of fglrx that supports kernel version 3.5 of Ubuntu Quantal.

I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl + Shift + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).

Before you start
If you have previously attempted installing Catalyst, remove any leftover files by following the Removing the Driver section. Make sure universe and multiverse are enabled in your repository sources (System -> Administration -> Software Sources). or Applications->Ubuntu Software Center->Edit->Software sources->Other software: check canonical partners.

Install the prerequisite packages: sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4

If you are using the x86_64 architecture (64 bit): sudo apt-get install lib32gcc1

Download the latest Catalyst package
This package contains both the 32-bit and 64-bit driver. mkdir catalyst && cd catalyst wget --referer='http://support.amd.com/en-us/download/desktop?os=Linux+x86' http://www2.ati.com/drivers/linux/amd-catalyst-omega-14.12-linux-run-installers.zip unzip amd-catalyst--linux-x86-x86-64.zip chmod +x fglrx-14.10.1006/amd-driver-installer-14.10.1006-x86.x86_64.run

Install additional dependencies
sudo apt-get install -y xserver-xorg-dev

Create and install .deb packages
sudo ./fglrx-14.10.1006/amd-driver-installer-14.10.1006-x86.x86_64.run --buildpkg Ubuntu/saucy sudo dpkg -i fglrx*.deb

If building .deb packages fails you can try an Alternative Manual Installation which does NOT create deb packages and might cause some trouble when trying to uninstall.

Download the latest Catalyst package
This package contains both the 32-bit and 64-bit driver.

mkdir catalyst-14.3beta1.0 && cd catalyst-14.3beta1.0 wget --referer='http://support.amd.com/en-us/download/desktop?os=Linux+x86' http://www2.ati.com/drivers/beta/Linux_AMD_Catalyst_14.3_Beta_V1.0_B22_March12_2014.zip unzip Linux_AMD_Catalyst_14.3_Beta_V1.0_B22_March12_2014.zip cd fglrx-13.35.1005

Create and install .deb packages
sudo ./amd-driver-installer-13.35.1005-x86.x86_64.run --buildpkg Ubuntu/saucy sudo dpkg -i fglrx*.deb

If building .deb packages fails, there is also an Alternative Manual Installation

In case of failure
Remember these steps before you reboot your computer.

If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.

sudo startx

If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of "Could not stat /usr/lib64/fglrx/switchlibGL" which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/.

If all else fails, revert your xorg.conf and reboot.

sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf

This should return your original display.

Generate a new /etc/X11/xorg.conf file
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file. It is entirely dependent on your configuration. The following subsections will attempt to address possible (and tested) variations for their respective configurations.

Generic Config
This will work for most people: sudo amdconfig --initial -f

Minimal Config
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that's not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:

Section "Device" Identifier "ATI radeon 6870" Driver "fglrx" EndSection

X2/Dual GPU Cards
If you have an X2 card (e.g. 5970), use... !!Do not use for two separate cards in crossfire!! sudo amdconfig --initial -f --adapter = all

Dual/Multi Monitors
If you have a dual monitor display (also known as "Big Desktop"), use: sudo amdconfig --initial -f sudo amdconfig --set-pcs-str = "DDX,EnableRandR12,FALSE" This was confirmed in http://phoronix.com/forums/showthread.php?t=18553. Be advised that you may need to manually set the correct refresh rate for your second monitor through catalyst.

Force use of the new xorg.conf (if necessary)
Some people find that changes to xorg.conf don't get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:

sudo amdconfig --input=/etc/X11/xorg.conf --tls=1

Test your installation
NOTE: if you don't reboot first, fglrxinfo gives an error message. Reboot the computer and type fglrxinfo into the terminal. If the vendor string contains ATI, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns: display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI Radeon HD 4550 (This line may be different depending on what graphics card you are using.) OpenGL version string: 3.3.11566 Compatibility Profile Context (This line may be different depending on what graphics card and Catalyst version you are using.) Now, try: fgl_glxgears If you experience issues or a hang, you may need to disable fast TLS. sudo amdconfig --tls=0

Just in case
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn't work.

Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b

These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: "Raising Skinny Elephants Is Never Utterly Boring".

An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: "BUSIER" or remembering a phrase: "Restart Even If System Utterly Broken". This would also safely shutdown the system.

= Hardware Video Decode Acceleration (EXPERIMENTAL) =

Using XBMC player (XvBA)
XBMC has added support for accelerating video using XvBA/libxvba directly, but the support is currently not in the xbmc package in Ubuntu's repositories. To install the XvBA-enabled version of xbmc:

sudo apt-add-repository ppa:wsnipex/xbmc-xvba sudo apt-get update sudo apt-get install xbmc

NOTE: deprecated as of october 2013. Moved to ppa:wsnipex/xbmc-fernetmenta-master

Using the xvba-va driver (VA-API)
NOTE: The VA-API wrapper for XvBA has been dead code for a while now. It will probably give you some acceleration of HD formats, but using the previously mentioned xbmc PPA is a better solution.

This is confirmed to work for newer RadeonHD GPU's (those with UVD2). If you have a RadeonHD 4000-series or newer, you have UVD2. To see the complete list: http://en.wikipedia.org/wiki/Unified_Video_Decoder#UVD_enabled_GPUs

sudo apt-get install xvba-va-driver

A good player the utilizes va-api is VLC. You can enable va-api in Tools -> Preferences -> Input and Codecs. Check the box named "Use GPU accelerated decoding" and then restart VLC.

Test the xvba-va driver (VA-API)
The tool "vainfo" allows you to test the proper functioning of the xvba-va driver.

sudo apt-get install libva-glx1 libva-x11-1 vainfo vainfo

vainfo should return something like the following (and no errors): libva: libva version 0.32.0 Xlib: extension "XFree86-DRI" missing on display ":0.0". libva: va_getDriverName returns 0 libva: Trying to open /usr/lib/dri/fglrx_drv_video.so     libva: va_openDriver returns 0 vainfo: VA API version: 0.32 vainfo: Driver version: Splitted-Desktop Systems XvBA backend for VA-API - 0.7.8 vainfo: Supported profile and entrypoints VAProfileH264High              :	VAEntrypointVLD VAProfileVC1Advanced           :	VAEntrypointVLD

If vainfo returns an error, you may need to create a symlink:

sudo ln -s /usr/lib/va/drivers/fglrx_drv_video.so /usr/lib/x86_64-linux-gnu/dri/fglrx_drv_video.so #for 64-bit sudo ln -s /usr/lib/va/drivers/fglrx_drv_video.so /usr/lib/dri/fglrx_drv_video.so #for 32-bit

Other
There is possibility to enable > H.264 Level 5.1 decoding in the driver which "has been in the driver for some time but not enabled by default". This only applies for pre-12.11 beta releases of the drivers. Since 12.11 beta the setting is enabled by default

sudo amdconfig --set-pcs-u32=MCIL,HWUVD_H264Level51Support,1

or

sudo service lightdm stop sudo cp -p /etc/ati/amdpcsdb  /etc/ati/amdpcsdb.bak sudo sed -i '/UvdEnabled=V1/ a HWUVD_H264Level51Support=V1' /etc/ati/amdpcsdb sudo reboot

=Updating Catalyst/fglrx=

DO NOT try to install a new version over an old one. Follow the 'Removing Catalyst/fglrx' section below to remove your existing driver, and then you can start at 'Downloading the latest Catalyst' to install the new one.

=Removing Catalyst/fglrx= The uninstall script in the first command will only exist if you downloaded the drivers and installed them directly (rather than building packages as this guide does). Skip the first command if it does not exist. sudo sh /usr/share/ati/fglrx-uninstall.sh sudo apt-get remove --purge fglrx*

If you plan on using open-source drivers, you will need to reinstall some packages because Catalyst overwrites or diverts some key 3D libraries with proprietary versions. For more information on this issue, see this Ubuntu wiki page sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon sudo apt-get install xserver-xorg-video-ati sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup sudo rm -f /etc/ati

If you receive

$ E: Internal Error, No file name for libgl1-mesa-dri

Change the third command above to:

sudo apt-get install --reinstall libgl1-mesa-glx:i386 libgl1-mesa-glx:amd64 libgl1-mesa-dri:i386 libgl1-mesa-dri:amd64 xserver-xorg-core

= Issues =

Video Tearing
AMD/ATI claims that the "Tear Free Video" option is enabled by default, but that wasn't the case with Catalyst 12-3 installed on Kubuntu 12.04. If you're having issues with tearing, make sure that "Tear Free Video" is on. You can find this option in the Catalyst Control Center under 'Display Options' or you can use the following command: sudo amdconfig --sync-video=on The option will not take effect until you restart X (i.e. log out).

If you're using compositing, you should also make sure that vsync is enabled in the compositor's settings. I found that vsync was enabled by default, but here are the appropriate settings should you want to experiment.

kwin
You can enable vsync for kwin in System Settings -> Desktop Effects -> Advanced tab

Compiz (Unity/GNOME-Shell)
TODO: See if there's a friendlier way to make sure vsync is enabled without installing ccsm.

Install the compiz settings manager: sudo apt-get install compizconfig-settings-manager ccsm

The 'Sync to Vblank' is found in the 'OpenGL' subsection of the 'General' group

Hybrid Graphics and Catalyst
There are two basic types of hybrid designs. Older hybrid systems use a multiplexor (mux) to switch between GPU's. Newer systems (those with PowerXpress >= 4.0) are muxless. As far as I can tell, PowerXpress 4.0 started with RadeonHD 6000-series GPU's, and systems with older ATI GPU's have a mux, but don't quote that.

ATI/ATI Hybrids
As of Catalyst 11-8, switching between two ATI cards (and maybe Intel/ATI muxless too?) is supposed to be doable, though it's not clear if that applies to all ATI/ATI hybrids or only the muxless ones. One would use amdconfig's PowerXpress options to switch back and forth between the integrated and discrete cards, like so:

amdconfig --pxl           # List current activated GPU sudo amdconfig --px-dgpu  # Activate discrete GPU (High-Performance mode), must re-start X to take effect sudo amdconfig --px-igpu  # Activate integrated GPU (Power-Saving mode), must re-start X to take effect

After switching, one would log out and back in to restart X.

Intel/ATI Hybrids
By using the officially provided drivers, there are three problems ( Launchpad Bug: #1068404):
 * An incompatibility problem between intel and fglrx drivers (This gives segmentation fault at X server)
 * An incompatibility problem between intel and fglrx drivers that gives an error related to allocation of resources in Xorg log file.
 * Some paths missing for openGL operation of the fglrx driver (This prevents applications that require direct rendering, e.g. Unity/games/etc, from loading correctly)

If you follow the instructions described in the Binary Driver HOWTO, you should get functional configuration.

If however you suffer from the problem related to intel driver not able to allocate resources, you need to install the older intel driver 2.20.2-1ubuntu1 which can be found at https://launchpad.net/ubuntu/quantal/+source/xserver-xorg-video-intel

There is still another bug if you use the integrated GPU (Intel), making the X server crashing ( Launchpad Bug: #1088220 )

A workaround for now is to use the discrete GPU (ATI)

For more information you may want to follow this forum topic

This post got both the integrated (Intel 3rd Gen Core processor Graphics Controller) and discrete (Radeon HD 7670M) to work on Ubuntu 13.04 x64.

Build Fails and Log Shows "mixed implicit and normal rules. Stop."
If the installation fails and you find the above message in /var/lib/dkms/fglrx//build/make.log, it may be because you're using a pentium-build wrapper around gcc. See what the following ls command returns: ls -la /usr/bin/gcc If it shows that gcc is a link to builder-cc, temporarily redirect the link to point to the real gcc (gcc-4.8 in Ubuntu Saucy). This should allow you to install fglrx: sudo ln -sf /usr/bin/gcc-4.8 /usr/bin/gcc When you're finished installing the driver, return the gcc link to its original value: sudo ln -sf /usr/bin/builder-cc /usr/bin/gcc Launchpad link for this bug: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/555957

"Errors were encountered while processing: fglrx-amdcccle" (on 64-bit systems)
Most likely, you probably did not have the ia32-libs-multiarch:i386 lib32gcc1 libc6-i386 packages installed beforehand. If you have a 64 bit install, the above dpkg command may complain that "Errors were encountered while processing: fglrx-amdcccle". This is because of a dependency of the amdccle package on 32 bit libraries. If you receive this error, use the following command, which will force the installation of all of the 32 bit dependencies, and then the amdcccle package:

sudo apt-get -f install

Catalyst on 64-bit systems may require the --force-overwrite command in the above dpkg command: sudo dpkg -i --force-overwrite fglrx*.deb

Problems Starting Xserver
If you get a black screen hang, the first thing to check is if xorg.conf is the problem.

You can disable the xorg.conf with: sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.disabled

Reboot and check to see if things work now.

You can reinstate the file with: sudo mv /etc/X11/xorg.conf.disabled /etc/X11/xorg.conf

Before tweaking ACPI settings, try ensuring /dev/null is chmodded to 0666. This intermittently changes when using the nano (and possibly other) editors with sudo and the group/world permissions are unset. This leads to the ATI drivers hanging on boot or otherwise. A quick and dirty init script saved as /etc/init/chmodnull does the trick -

start on filesystem

script chmod 0666 /dev/null chmod 0666 /lib/udev/devices/null end script

This has been tested using Ubuntu 10.04 64-bit on a ATI Radeon HD 4830 (HP Envy 15-1060ea). It's worth noting that I had to disable TLS (amdconfig --tls=0) to get things to stay stable!

If you've properly installed the driver, but experience problems when starting the X server, such as hanging, black/white/gray screen, distortion, etc., your system BIOS may have a buggy ACPI implementation. To work around, press Ctrl+Alt+F1 to get to a terminal (or failing that, boot to recovery mode) and run: sudo amdconfig --acpi-services=off If this method works, you should consider checking your system vendor's BIOS changelogs for relevant ACPI fixes, updating your BIOS, and reenabling the driver's ACPI services.

Unsupported Hardware Watermark
This can happen if your card's PCI ID wasn't officially certified to work with a particular version of Catalyst. It does not necessarily mean that your card is unsupported, but it does mean that you shouldn't file bugs with that particular card/driver combination. If you installed the driver by downloading it from AMD/ATI, installing a newer version of Catalyst will probably help.

If you installed the proprietary driver included with Ubuntu or you do not want to upgrade to a newer version, it is possible to work around the issue. First check if AMD's signature file has a proper signature:

sudo nano /etc/ati/signature

If the file only contains the word UNSIGNED, replace the line with: 9777c589791007f4aeef06c922ad54a2:ae59f5b9572136d99fdd36f0109d358fa643f2bd4a2644d9efbb4fe91a9f6590a145:f612f0b01f2565cd9bd834f8119b309bae11a1ed4a2661c49fdf3fad11986cc4f641f1ba1f2265909a8e34ff1699309bf211a7eb4d7662cd9f8e3faf14986d92f646f1bc

Reboot and see if the watermark is gone. If not, try using a control file from a older version of Catalyst than the one you're running:

cd ~/; mkdir catalyst12.10; cd catalyst12.10/ wget http://www2.ati.com/drivers/linux/amd-driver-installer-catalyst-12.10-x86.x86_64.zip unzip amd-driver-installer-catalyst-12.10-x86.x86_64.zip chmod +x amd-driver-installer-catalyst-12.10-x86.x86_64.run ./amd-driver-installer-catalyst-12.10-x86.x86_64.run --extract driver sudo mv /etc/ati/control ~/control.bak sudo cp driver/common/etc/ati/control /etc/ati

Poor battery life (atieventsd not starting and/or not authenticating)
The atieventsd daemon is a daemon that monitors various acpi events (it does this by connecting with the acpid daemon), such as a laptop lid close, or an AC connect/disconnect, presumably to let the GPU know for reasons of power saving. See the man page for more info. On my system, `Ubuntu 13.10`, and with the latest drivers from Catalyst, 13.12, the daemon installs itself at `/etc/alternatives/x86_64-linux-gnu_atieventsd` with a symlink to that at `/usr/bin/atieventsd`.

The Sys-V-init script, `/etc/init.d/atieventsd` thinks the symlink is elsewhere, namely `/usr/sbin/atieventsd` (i.e. `sbin` not where it actually is, `bin`)

So to launch successfully the `atieventsd` on startup I had to do make the change:

DAEMONPATH=/usr/bin/atieventsd

Then remove/regenerate the run levels:

cd /etc/init.d   mv atieventsd atieventsd.temp update-rc.d atieventsd remove mv atieventsd.temp atieventsd update-rc.d atieventsd defaults

This should now at least allow the daemon to correctly start/stop. You can test with `service atieventsd start`.

On each startup the daemon attempts to launch a script, `/etc/ati/authatieventsd.sh` (by default), whose purpose is to grant the `atieventsd daemon` authorization access to the X server display, so it can send it various commands.

This script is called by `atieventd` like (see `ps aux | grep atieventsd` after starting the service or booting)

/etc/ati/authatieventsd.sh grant :0 /tmp/atieventsdGWt098

Here argument one (`$1`) is the action: *grant/revoke* , argument two (`$2`) is the X display number (e.g `:0`), and argument three (`$3`) is the file wanting the authority. See the `xauth` man page for some more background.

The problem is that if you look at the `/etc/ati/authatieventsd.sh` script you will see it does not support `lightdm`, you need to add the chunk of code inside the `GetServerAuthFile` function:

#Check lightdm LIGHTDM_AUTH_FILE=/var/run/lightdm/root/$1 if [ -e $LIGHTDM_AUTH_FILE ]; then SERVER_AUTH_FILE=$LIGHTDM_AUTH_FILE DISP_SEARCH_STRING="unix$1" return 0 fi

to allow it find the correct server authentication file. Save this and you should see a file in the `/tmp` directory of the form `atieventsdGWt098`, the next time the `atieventd` is stopped/start (or next reboot), and if you do

xauth -f /tmp/atievntX.Dh1AJV list

you should get something like

yourHostname/unix:0 MIT-MAGIC-COOKIE-1  98deg034234kkn34234mmm3242

Showing that the daemon has indeed been granted authority.

You can also look at syslog, if you add the `--debug` option to `/etc/init.d/atieventsd` init file DAEMONOPTS options (regen run levels), and you should see everything is now working correctly, and the daemon is responding to events such as unplugging the AC and lid closes. For example:

: ACPI event: ac_adapter AC 00000080 00000000 : ACPI event: processor CPU0 00000081 00000000 processor CPU1 00000081 00000000 processor CPU2 00000081 00000000 processor CPU3 00000081 00000000

Maybe this will help extend battery life.

Hang at logout
If you experience hangs when logging out (of X) it is probably due to the /etc/ati/authatieventsd.sh script looking for X authorization files in the wrong place when it starts up. You can kill the hanging authatieventsd.sh processes from a console tty to allow the shutdown of the X server.

Before the following commands verify that /etc/ati/authatieventsd.sh exists after build and install, if not just do: (assuming that the installer is in the directory we used to install)

cd ~/catalyst sh amd-driver-installer--x86.x86_64.run --extract driver sudo cp driver/packages/Ubuntu/dists/quantal/replacements/authatieventsd.sh /etc/ati/authatieventsd.sh sudo chmod +x /etc/ati/authatieventsd.sh

This problem can be fixed permanently with:

sudo mkdir -p /var/lib/xdm/authdir sudo ln -s /var/run/xauth /var/lib/xdm/authdir/authfiles

If that doesn't work then you can disable atieventsd with this command:

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

You'll have to restart for this to take effect.

Can't remove fglrx with dpkg (diversion issue)
If dpkg refuses to remove an fglrx package and complains about a diversion of a file, you might need to manually remove it. For example, if dpkg complains: dpkg-divert: mismatch on divert-to when removing `diversion of /usr/lib/libGL.so.1.2 to /usr/share/fglrx/diversions/libGL.so.1.2 by xorg-driver-fglrx' found `diversion of /usr/lib/libGL.so.1.2 to /usr/lib/fglrx/libGL.so.1.2.xlibmesa by xorg-driver-fglrx' then: sudo dpkg-divert --remove /usr/lib/libGL.so.1.2

This module/version combo is already installed
If you get this error-message, simply uninstall the previous version before installing the new one with: sudo dkms remove -m fglrx --all

New kernel installed?
In theory, DKMS should automatically install the fglrx kernel module for your new kernel the first time you boot it. Should you need to manually install it: sudo dkms build -m fglrx -k `uname -r` sudo dkms install -m fglrx -k `uname -r`

if amdcccle doesn't work and says Identifier is not a valid word. Use lower case letter in xorg.conf or specify all the correct parameters. For example: sudo dkms build -m fglrx -v 9.012 -k 3.5.0-22-generic sudo dkms install -m fglrx -v 9.012 -k 3.5.0-22-generic

amdconfig not found after installation
This scenario is possible when the driver installation has seemingly succeeded and is possibly related to previous fglrx installs, including those through Jockey (i.e. you first used drivers provided by Ubuntu but then upgraded to ones available from AMD's website). When doing amdconfig --initial after driver installation, you might end up not having the amdconfig available at all: amdconfig: command not found After booting you might receive X error '(EE) Failed to load module "fglrx" (module does not exist, 0)'. These do not necessarily indicate that the installation has failed completely. On command line, do ls /usr/lib/fglrx/bin and see if the command lists some Ati related programs. If they are listed but not found from /usr/bin, it is possible that the "update-alternatives" fglrx .deb installation does has been ignored. See man update-alternatives for more information about the concept and workings of alternatives. In practice, update-alternatives is supposed to create several symbolic links to the files in the fglrx directory, but it will be ignored if the alternatives for the very related gl_conf entry has been set to manual. Do update-alternatives --get-selections | grep gl_conf and see if the mode is manual instead of auto and if mesa is mentioned instead of fglrx in the path that is printed. In this case you need to sudo update-alternatives --set gl_conf /usr/lib/fglrx/ld.so.conf to set fglrx as the active alternative. You can alternatively (no pun intended) and additionally change the gl_conf into automatic mode before the installation this way: sudo update-alternatives --auto gl_conf After that, the alternatives should automatically be configured correctly when the graphics driver .debs are installed.

"update-alternatives: error" during install
