You have been subscribed to a public bug: 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.
