With vgaswitcheroo one of the graphic adapters can be switched off. On battery (e.g., while traveling) the integrated GPU consuming less energy can be used. With access to a power supply the discrete more powerful GPU could be used if necessary. Also, with the discrete GPU deactivated, the noise of the cooling fan can be reduced. -- Best regards, Jörg-Volker. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
