I can only use the integrated Intel graphics with poor 3D support: The propretary ATI fglrx driver fails with switchable graphics turned on and suggests to turn switchable graphics off. The free radon driver does not yet support the HD 56xx series. Other Laptops with this constallation allow to turn off the switchable graphics in BIOS and to choose either integrated or discrete graphics. Now I am in a mess since my notebook (HP Envy 14) has no such BIOS option; I am stuck with Intel graphics and a non-working power plan. openSUSE's kernel 2.6.34 comes with vgaswitcheroo, a functionality to switch graphic cards at runtime. It correctly identifies both the Intel and the ATI graphic cards. It shows that both cards are powered and that the Intel card is selected. I switched to the ATI card and turned off the Intel card. ATI driver still fails, but with message "Unknown BIOS". According to ATI, the only option is to switch the Intel card dead in BIOS. :-( Maybe, bug 619869 is related somehow?
