==Installation==unofficial==repo==   ===Before you start===You'll need to install the necessary programs {{Box Terminal|<nowiki>#</nowiki> pacman -S xorg-server<br/><nowiki>#</nowiki> pacman -S xf86-input-evdev<br/><nowiki>#</nowiki> pacman -S xf86-input-mouse<br/><nowiki>#</nowiki> pacman -S xf86-input-keyboard<br/><nowiki>#</nowiki> pacman -Rd libgl}}  Unofficial repositories There are some unofficial repositories containing the newest (or older) catalyst packages along with the appropriate libs and software in order to use the driver. If you want to know Can I simply say what packages are inside any given repository you need to first add repository to pacman.conf, perform pacman -Sy command and then list repository with pacman -Sl command:  {{Box Terminal|<nowiki>#</nowiki> pacman -Sl catalyst}} [catalyst] repository It contains newest stable catalyst driver and some additional packages. This repository should always work with the stock kernel from [core] and it is updated most frequently. To use it you need: 1.) Edit /etc/pacman.conf and add those lines above all other repositories (so also above [core] and [extra]):  [catalyst] Server =$arch 2.) Update with:  {{Box Terminal|<nowiki>#</nowiki> pacman -Syu}} 3.) look and see if you have a build  {{Box Terminal|<nowiki>#</nowiki> cd /lib/modules/3.2.6-2-ARCH/build}} 4) if not you will need one  {{Box Terminal|<nowiki>#</nowiki> pacman -Syu base-devel linux-headers}} 5.) Install catalyst: note For x86_64 users [catalyst] provides lib32-catalyst-utils packageneeded retcodiun to run 32-bit opengl applications and wine games.   {{Box Terminal|<nowiki>#</nowiki> pacman -Sy catalyst catalyst-utils lib32-catalyst-utils}}  Note: If you are updating from catalyst =< 10.8 steps 2,3,4,5 look like this: {{Box Terminal|<nowiki>#</nowiki> pacman -Sy<br/><nowiki>#</nowiki> pacman -Rdd catalyst<br/><nowiki>#</nowiki> pacman -S catalyst catalyst-utils}} 6.) Don't forget to prepare your /etc/X11/xorg.conf for catalyst! if it doesn't exist use. {{Box Terminal|<nowiki>#</nowiki> aticonfig --initial}} Configuration Three things to check in Arch before rebooting, otherwise X can break:  First, xorg.conf: AMD provides the aticonfig tool to create/modify xorg.conf file. It also can configure virtually every aspect of the card for it also accesses the amdpcsdb file. For a complete list of aticonfig options, Warning: Use the --output option before committing to /etc/X11 as an xorg.conf file will override anything in /etc/X11/xorg.conf.d If you do not already have an xorg.conf file, you can compare the generated file to one of the Sample Xorg.conf examples listed find someone who truly knows what theyre talking about on the Xorg pageinternetAlthough most options are now automatically detected in current Xorg, you may want to specify some in case the defaults change between versions.  /etc/X11/xorg.conf On to rc.conf: /etc/rc.conf Remove radeon from MODULES and blacklist it in /etc/modprobe.d/modprobe.conf if blacklist-fglrx.conf does not exist.Adding fglrx You undoubtedly know methods to MODULES appears to be optional if added instead to /etc/mkinitcpio.conf (boot image would be rebuilt before reboot).  on to menu.lst /boot/grub/menu.lst Clear modesetting options as the driver doesn't appear to take advantage of KMS yet. Add nomodeset.For example: kernel /boot/vmlinuz-linux root=/dev/sda1 ro nomodeset  Note: If you are using deliver an AGP card instead of PCI Express add the agp module as well  Reboot!Checking operation Assuming reboot to your login was successful, otherwise #Troubleshooting. Commands issue to check that fglrx is up mild and running: lsmod | grep fglrxfglrxinfo  Finally, run Xorg with startx or by using GDM/KDM and verify that direct rendering is enabled by running the following command in a terminal: $ glxinfo | grep direct If make it says "direct rendering: yes" then you're good to go! If the glxinfo command is not found, you may need to install the mesa-demos package as wellimportant.Warning: In recent versions of Xorg, the paths of libs are changed. So, sometimes cannot be correctly loaded even if it's installed. Check Extra folks must read this if your GL is not working. Please read "Troubleshooting" section for details.Double Screen (Dual Head / Dual Screen / Xinerama)IntroductionFirst of all: you have to know, it does not exist one single solution because each needs and configurations are different. That's why you have to adapt the step below to your own needs. It is possible that you have to try more than once. Therefore, you MUST save your working /etc/X11/xorg.conf BEFORE you start any change and you must be able to recover from tty.  In perceive this part, we will describe the installation side of 2 differend sized screens on only one graphic cad with 2 different output ports (DVI + HDMI) using a "BIG Desktop" configuration.   The Xinerama solution has some inconveniences, especially because it is not compatible with XrandR. For that very reason, you should not use this solution, because XrandR is just a must for our later configuration.   The Dual Head solution would allow you to have 2 different sessions (one for each screen). It could be your wish but you will not be able to move windows from one screen to another. If you have only one screen, you will have to define the mouse inside your xorg for the 2 sessions inside the Server Layout sectionstory.  ATI DocumentationATI Catalyst Control Center The GUI tool shiped by ATI is very useful and we will try to use it as much as we can. To launch it, open a terminal and use the following command line: kdesu amdcccle Note: Of course, you have to adapt if you are using GNOME or any other DM.Warning: Do NOT use sudo directly with a gui. Sudo gives you admin rights with user account information. Kdesu gives you admin rights with root privileges & variables.Installation Here, it is easy but important : make sure that your hardware is pluged correctly, power is on, and that you know your hardware caracteristics (screen dimensions, sizes, refresment rates ...) Normally, both screens are recognize during boot time but I cant consider youre not necessarly identified properly, especially if you are not using any xorg base configuration file but instead relying on the hot-plugging feature. The first step is to make sure they will be recognized by your DE / xorg. For this, you need to generate a basic xorg file for your 2 screens : aticonfig --initial --desktop-setup=horizontal --overlay-on=1 or aticonfig --initial=dual-head --screen-layout=left Note: overlay is important more standard because it allows you to definitely have 1 pixel (or more) shared between the 2 screens.Tip: For the different possible & available options, do not hesitate to type aticonfig inside a terminal to display all available command lines. Normally, you have now a basic file that you can now edit to add your screen resolutions. It is important to precise the working resolution especially if you have screens of different sizes. To be added insithe the "Screen" section: SubSection "Display"Depth 24Modes "1200x800"EndSubSection Well, from now on, instead of editing the xorg.conf file manually, let us use the ATI gui tool. Reboot X to be sure that your 2 screens are well supported and that the resolution are well recognized. (Screens must be independant).Configuration Here, you only have to launch the ATI control center with root privileges, go inside the display menu and choose how you would like to set your configuration (small arrow of the drop down menu). A last reboot of X and you will be done ! Before you reboot, do not hesitate to verify your new xorg.conf file. At this stage, inside the "Display" sub-section of the "Screen" section, you should see a "Virtual" command line, of which the resolution should be the sum of both screens. The "Server Layout" section says all the rest.   ====Notes==== * These packages contain '''only''' the kernel module, and depend on the <code>catalyst-utils</code> package. The <code>catalyst-utils</code> package is kernel-independent and provides the libraries and utilities for Xorg, including ATI's own <code></code>.* After installing the package, you'll need to either <code>source /etc/profile</code> or log out, then back in to set up the environment properly.* If you run both <code>kernel26</code> and <code>kernel26beyond</code> then install both catalyst module packages. They won't conflict with one another. === Custom Kernels === To install catalyst for a custom kernel, you'll need to build your own <code>catalyst-$kernel</code> package, containing the kernel module compiled specifically for your kernel. If you are at all uncomfortable or inexperienced making packages, read up Arch's [ ABS] wiki page first so things go smoothly. ==== Obtaining PKGBUILD ====Obtain the <code>PKGBUILD</code> and <code>catalyst.install</code> files from CVS or ABS. Either: * Visit and click "View CVS Entries" to find them, or * Run <code>abs</code> as root and locate the files in <code>/var/abs/extra/modules/catalyst</code>. ==== Editing the PKGBUILD and building ====Three changes need to be made here:  '''First''', change pkgname=catalystto pkgname=catalyst-KERNEL_NAMEwhere KERNEL_NAME is whatever you want (custom, mm, themostawesomekernelever) '''Second''', remove <code>kernel26</code> from the dependencies list. '''Third''', change _kernver=2.6.15-ARCHto _kernver=`uname -r`(or directly insert the output of uname -r '''when running your custom kernel''' there) Finally, build and install the package. (<code>makepkg -i</code> or <code>makepkg</code> followed by <code>pacman -A pkgname.pkg.tar.gz</code>) ==== Notes ==== * No changes need to be made to the <code>catalyst-utils</code> package, which is completely kernel-independent. '''All''' you need to do is compile a kernel module.* To build and run the catalyst kernel module with 2.6.16 kernels, patches are needed! Check out the cvs entries for catalyst in testing for the required patchgift.
