Hi list, i have a somewhat silly question: Probably you heard about the "switchable graphics" built into some modern notebooks. Right now, switching while working is only supported under Vista. For Linux, users had to select the graphic card in the BIOS. Lenovo e.g. offers three options there: Integrated - (Intel on, ATI off) , Discrete - (Intel off, ATI on) and Switchable - (Intel on, ATI on, screen "connected" to Intel). I have a new Acer Timeline notebook with switchable graphics, but here "Integrated" in the BIOS is missing. If i set my BIOS to "switchable", the notebook consumes about 20W of power. If i set it to "Discrete", RadeonHD or fglrx enter power saving and i get about 10W. Under Vista running on intel it goes down to 7W. My guess is: When i switch to "Switchable", the ATI chipset is running (at full power as no driver starts the saving-mode). The Vista driver then turns ATI off (when using Intel, of course). Could i set it via AtomBIOS to an "off"-state? I found ATOM_PM_OFF in atombios.h, could this be helpful?
