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:

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...
Cheers.
I've a kind of sort of interest in the optimus ( and yeah more & more users are hit by this ) I've the chance to be able to desactivate optimus in the bios, and just work with the nvidia quadro. (At least I've 4.5 hours of autonomy and that's okay for me) -- Bruno Friedmann Ioda-Net Sàrl www.ioda-net.ch openSUSE Member & Ambassador GPG KEY : D5C9B751C4653227 irc: tigerfoot -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
