Hi: This is the second part of the xps15z saga.. but will anyways affect a lot of users regardless whatever laptop model used.. This box has an integrated NVIDIA "optimus" http://en.wikipedia.org/wiki/Nvidia_Optimus , which has no support in linux, I can certainly live just fine with the intel GPU alone.. I couldn't care less about this thingy, however, the nvidia device 01:00.0 VGA compatible controller: nVidia Corporation Device 0df5 (rev ff) remains "on" and is a power hog, taking at least 1 hour of battery..there are all sorts of hacks outside to simple disable it. This particular one works for me: http://linux-hybrid-graphics.blogspot.com/2010/07/using-acpicall-module-to-s... however it is an out of tree kernel module and looks fairly hackish, is there any way to send acpi commands without using this "acpi_call" kernel module ? My idea is to create a package that pulled in, just disables the card in the meanwhile someone hacks support for this devices...
