This is on xUbuntu 14.04 LTS on amd64 workstation (Intel i7-3770), and as the original report notes using two monitors on the i7's GPU and a plug in nVidia GeForce 9600 for the third monitor. Machine is dual boot with Windows7, triple head works fine there.

xorg package version 1:7.7+1ubuntu8
nvidia-331 package version 331.38-0ubuntu7
nvidia-prime package version 0.6.2
nvidia-settings package version 331.20-0ubuntu8

results of get-acpi-info.sh posted to launchpad bug #752542.

git://github.com/Lekensteyn/acpi-stuff.git 's acpi_dump_info.c fails to build due to missing DEVICE_ACPI_HANDLE(), which was removed in linux 3.13; see launchpad bug #1267437.
