Christopher, Thanks for your message. I had assumed this report had been forgotten about. The instability issues on the machine with the AMD Radeon 5000M have been resolved and the triple head setup is working perfectly on Ubuntu 13.10 (from a fresh install). The last time I checked, the machine with the AMD Radeon HD 6470M was still not handling triple head properly. The computer is with the manufacturer getting repaired right now, but is due to be returned before the end of January. Once I get it back, I can run the test you've requested and will report back here.

I can get either monitor to come on through either output extension but when trying to get both to work at the same time the graphics go crazy. Both displays are listed in GUI display manager--just don't come on as expected when changing display settings. I can get triple head to work with AMD Radeon 5000M video adapter (same software setup) but the displays go crazy when starting a virtual machine or Skype. FWIW, on the AMD Radeon HD 6470M system System Info states graphics as Intel® Sandybridge Mobile while on AMD Radeon 5000M graphics are listed as Gallium 0.4 on AMD REDWOOD. Any thoughts or advice welcome.
