In ubuntu11.10 , I still need to use open source drive of ATI when using Switcheroo ? The 'addon driver' in system menu is about open drive or propriety driver ? Thanks
1 Answer
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. Jan 27, 2012 at 18:23
