Title:
  Dual head failing with Radeon [workaround]

Status in fglrx-installer package in Ubuntu:
  Invalid

Bug description:
  I spent almost one week (not intensivelly) to fix AMD Radeon dual head
  configuration.

  This is for sure the most user unfriendlyness configuration i've ever
  seen.

  This where the steps i'd to use to be able to configure it (somewhat):

  How to make latest AMD HD Radeon drivers to work on dual-head?

  1. Download and install drivers

  Drivers are available at:
  http://support.amd.com/us/gpudownload/Pages/index.aspx

  Select the options and download the driver

  2. Setup drivers

  Open a terminal option and run
  sudo amd-driver-installer-xxx-xxx-x86.x86_64.run
  sudo apt-get install gtk2-engines-pixbuf

  sudo aticonfig --initial=dual-head -f
  sudo aticonfig –set-pcs-str=”DDX,EnableRandR12,FALSE”

  Edit /etc/X11/xorg.conf

  There should exist two Section “Device”, one for device 0 and another for device 1.
  Copy the Option “UseFastTLS” “1” from device 0 to device 1. Device 1 should be noted with a Screen 1 entry.

  Force X to use the new configuration with:

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

  3. Reboot

  4. Call amdccle

  Call amdccle either from a terminal with:

  gksu amdccle

  or on the “app search” of Unity type “amd” and it should appear both
  with and without administrative powers. Choose the one with
  administrative powers.

  On the Multi-Display choose:

  “Multi-display desktop with display(s) 1 or 2, depending on which you
  want to be the primary display. [they could have a flag on each
  display to tick when you want to swap who is primary, easier to
  understand which will be the primary]

  5. Reboot
  6. Repeat step 4 (no kidding, at first time, the multi-display will be setup as clone not as we asked).
  7. With lots of luck you ended up like me, with a dual-head computer and both monitors working properly!

  
  Notes:

  If you don't issue the “dual-head” on the aticonfig, it may not pick
  the second monitor.
