Hi! My name is Edvard Karlsen. Great to see so many people interested in working towards an implementation of this functionality in Linux! I'm currently running the dual-graphics UL 30 JT.
I managed to rework the asus_nvidia.c ( http://ubuntuforums.org/showthread.php?t=1366605) kernel module to (at least) disable the separate 310M card on the laptop. The ACPI handle is \_SB.PCI0.PEG1.GFX0._OFF, an exact variant not found yet on http://linux-hybrid-graphics.blogspot.com/2010/01/current-list-of-linux-switchable.html as far as I can see. I'll experiment more (reenable, run on separate card, etc..) as soon as I've got some spare time. I'll post my DSDT.dsl to launchpad asap. $ dmidecode -s system-product-name UL30JT $ dmidecode -s system-version 1.0 $ lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA 00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 12) 01:00.0 VGA compatible controller [0300]: nVidia Corporation Device [10de:0a70] (rev ff) (prog-if ff)
