Switcheroo works for open-source drivers only (radeon, i915, nouveau). The Additional drivers program tries to install proprietary drivers which do not work with switcheroo.

Uninstall the fglrx driver (and possibly reboot). The radeon driver should be installed by default. – Lekensteyn Jan 27 '12 at 18:23
