Charles, Have you checked if the device is still listed in lscpi? What is your battery state (power drain) before and after you switch it off? IIRC, /proc/acpi/battery/BAT0/state or acpi -b should be helpful.
If it is really off, I'd expect the device not show up in lspci and your battery state should show a lower value. If you shut it off successfully, it is good news, as it means battery life will be increased. Keep us posted :) Regards, Olibob 2010/8/22 charles <[email protected]> > I believe you can turn off the nvidia card with vgaswitcheroo: > > % cat /sys/kernel/debug/vgaswitcheroo/switch > 0:+:Pwr:0000:00:02.0 > 1: :Pwr:0000:01:00.0 > % echo OFF | sudo tee -a /sys/kernel/debug/vgaswitcheroo/switch > OFF > % cat /sys/kernel/debug/vgaswitcheroo/switch > 0:+:Pwr:0000:00:02.0 > 1: :Off:0000:01:00.0 > > At the moment I'm not even able to suspend or hibernate - hopefully > hardware support for these kind of hybrid gfx laptops improves in the > future! > > On Sun, Aug 22, 2010 at 3:49 AM, john L <[email protected]> wrote: > > Hello! > > I use the default ubuntu 10.10 settings.
