Yeah that might be the case but the document http://www.nvidia.com/object/LO_optimus_whitepapers.html about nvidia optimus basically says that the datapath to the physical monitor is always through the Intel IGP and then the IGP is responsible for writing to the display. The nVidia chip is between the application and the IGP, therefore I expected that the IGP would be connected to the HDMI port. However I'm probably wrong and would appreciate if you or someone could clarify my understanding about how this is meant to work. The laptop is a Dell XPS 15z (http://reviews.cnet.com/laptops/dell-xps-15z/4507-3121_7-34714594.html) _______________________________________________ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com
