(chroot) # ##i##emerge -s debian-sources
<tt>x11-drivers/ati-drivers</tt> (often referred to as "<tt>fglrx</tt>", the name of its kernel module) is the proprietary, accelerated driver for AMD (ATI) graphics cards.

=== Blacklist Radeon and DRM Modules ===

      ##g##Latest version available:##!g## 3.19.3
To avoid having the open source Radeon drivers automatically load and ruin your day, create a blacklist file as follows:
      ##g##Latest version installed:##!g## 3.19.3
 
      ##g##Size of files:##!g## 81,292 kB

}}


=== Configuring the kernel ===
If a version is listed under {{c|Latest version installed}}, then debian-sources is already pre-built for you and you can skip the rest of the Kernel section, and proceed to the [[#Installing a Bootloader|Installing a Bootloader section]].


Configure the kernel as follows. Note that the Direct Rendering Manager is '''not''' enabled. It's possible to have it selected as a kernel module, but should not be built-in to your kernel.
==== Building the Kernel ====

{{note|If you need support for AGP cards, enable the following kernel options:}}

                  Select an appropriate AGP driver:
                  <*> AMD Opteron/Athlon64 on-CPU GART support
}}


=== Editing make.conf ===
{{fancyimportant|1=
<code>debian-sources</code> with <code>binary</code> USE flag requires at least 14GB free in <code>/var/tmp</code> and takes around 1 hour to build on a Intel Core i7 Processor.}}


Add the following to your <code>/etc/make.conf</code>:
Let's emerge our kernel:
<console>
# ##i##nano /etc/make.conf
VIDEO_CARDS="fglrx"
</console>
=== Enabling AMD Catalyst Control Center ===


Then, add the following to <code>/etc/portage/package.use</code> if you would like to enable support for AMD Catalyst Control Center:
<console>
<console>
###i## nano /etc/portage/package.use
(chroot) # ##i##emerge debian-sources
x11-drivers/ati-drivers qt4
</console>
</console>


{{Note|If you are using a desktop or workstation profile, this USE flag will be enabled by default.}}
Once <code>emerge</code> completes, you'll have a brand new kernel and initramfs installed to <code>/boot</code>, plus kernel headers installed in <code>/usr/src/linux</code>, and you'll be ready to configure the boot loader to load these to boot your Funtoo Linux system.


== Installing ==
{{fancynote|NVIDIA card users: the <code>binary</code> USE flag installs the Nouveau drivers which cannot be loaded at the same time as the proprietary drivers, and cannot be unloaded at runtime because of KMS. You need to blacklist it under <code>/etc/modprobe.d/</code>.}}
 
=== Emerging the package ===
 
If you allready have emerged xorg-server, all you need to install the drivers is running the following command:
<console>
###i## emerge -av --changed-use --deep @world
</console>
 
otherwise you may install the drivers with
<console>
###i## emerge -av x11-drivers/ati-drivers
</console>
 
Before using the driver, ensure that the "fglrx" module has been loaded -- run {{c|modprobe fglrx}} as root  -- it should return with no error. If the module can't be found, run {{c|depmod -a}} as root -- then the modprobe command should work. If you are switching from the open source Radeon driver, then shutting down your desktop and rebooting your system (be sure to disable xdm) may be required to get the new "fglrx" module to load cleanly.
 
== Configuring ==
 
Next, set ati-drivers to manage the system's OpenGL and OpenCL implementations:
<console>
###i## eselect opengl set ati
###i## eselect opencl set amd
</console>
 
Afterwards, run <code>aticonfig</code> to modify the X-server configuration file to work with the ati-drivers:
<console>
###i## aticonfig --initial
</console>
 
{{tip|If you would like to have a full-resolution framebuffer with ati-drivers, check out [[uvesafb| uvesafb]]}}
 
=== Multi-Head Display ===
 
To enable a multi-head display, you'll need to use the Catalyst Control Center {{c|amdcccle}} GUI configuration tool, which is enabled by the {{c|qt4}} USE variable.
 
Open up a graphical terminal, and become root by typing {{c|su -}} -- your user will need to be in the {{c|wheel}} group to do this:
 
{{console|body=
$ ##i##su -
Password: ##i##*******
# source /etc/profile
# amdcccle
}}
 
[[File:amdcccle.png|class=img-responsive|center]]
Navigate to Display Manager, and choose the option {{c|Multi-display desktop with display(s) X}} for each display. Then, drag and drop the blue displays to arrange them to match how they are arranged in front of you. Click {{c|OK}}. The Catalyst Control Center will tell you that you will need to restart your system for the changes to take effect. Simply log out if you are running {{c|xdm}}, or end your X session, and start it up again. You should now have a fully-functioning multi-head display.
 
== Troubleshooting ==
=== I am using a HDMI connection, and my monitor's display has a black border around it. ===
Disable overscan using the following command, as root:
 
<console>
# ##i##aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0
</console>
 
You may need to restart your X session.
 
=== Compton with backend glx does not work well with ati-drivers ===
Try running compton with the following switches:
<console>
###i## compton --backend glx --vsync none --paint-on-overlay
</console>

   Note

This is a template that is used as part of the Installation instructions which covers: Kernel Installation. Templates are being used to allow multiple variant install guides that use most of the same re-usable parts.


Kernel

Starting mid-May 2015, Funtoo Linux stage3's include a pre-built debian-sources kernel to make installation faster and easier. To see if debian-sources is installed, type: 

(chroot) # emerge -s debian-sources

*  sys-kernel/debian-sources
      Latest version available: 3.19.3
      Latest version installed: 3.19.3
      Size of files: 81,292 kB
      Homepage:      http://www.debian.org
      Description:   Debian Sources (and optional binary kernel)
      License:       GPL-2

If a version is listed under Latest version installed, then debian-sources is already pre-built for you and you can skip the rest of the Kernel section, and proceed to the Installing a Bootloader section.

Building the Kernel

If you need to build a kernel for Funtoo Linux, please follow these steps:

   Note

See Funtoo Linux Kernels for a full list of kernels supported in Funtoo Linux. We recommend debian-sources for new users.

   Important

debian-sources with binary USE flag requires at least 14GB free in /var/tmp and takes around 1 hour to build on a Intel Core i7 Processor.

Let's emerge our kernel: 

(chroot) # emerge debian-sources

Once emerge completes, you'll have a brand new kernel and initramfs installed to /boot, plus kernel headers installed in /usr/src/linux, and you'll be ready to configure the boot loader to load these to boot your Funtoo Linux system.

   Note

NVIDIA card users: the binary USE flag installs the Nouveau drivers which cannot be loaded at the same time as the proprietary drivers, and cannot be unloaded at runtime because of KMS. You need to blacklist it under /etc/modprobe.d/.

   Note

For an overview of other kernel options for Funtoo Linux, see Funtoo Linux Kernels. There may be modules that the Debian kernel doesn't include, a situation where genkernel would be useful. Also be sure to see hardware compatibility information.
