Hello. I have an Asus U36JC laptop which has two graphic cards (NVIDIA Optimus technology): an Intel integrated card and GeForce 310M. To save power on Linux I use acpi_call module to disable nvidia card completely. This acpi_call module (https://github.com/mkottman/acpi_call) enables an interface to pass ACPI methods. Then when I issue echo '\_SB.PCI0.PEG1.GFX0._OFF' > /proc/acpi/call I'm disabling the nvidia card. Is something like that possible with FreeBSD? I'd like to use it on my laptop, but unfortunately it gets too hot when both Intel and Nvidia card are powered on. Are there any plans on supporting nvidia optimus? Or at least an option to disable the nvidia card and use the intel one? Regards, -- Bartek Krawczyk network and system administrator
