For an Optimus system I think the Intel side is the one that's actually connected to the monitor, but it can use the Nvidia GPU to render stuff. So you would need the Intel drivers, and either the proprietary driver from Nvidia or the free one called nouveau. You can read more about it here: https://wiki.debian.org/Bumblebee Debian does have a tendency to install all available drivers. Handy if you switch hardware, but not necessary. So most of the xserver-xorg -video-* packages can be removed, except the intel one (and possibly nouveau, not sure if it is needed). -- Cheers, Sven Arvidsson http://www.whiz.se PGP Key ID 6FAB5CD5
