    What: /sys/devices/.../power/control
Date: January 2009
Contact: Rafael J. Wysocki <rjw@rjwysocki.net>
Description:
 The /sys/devices/.../power/control attribute allows the user
 space to control the run-time power management of the device.
 All devices have one of the following two values for the
 power/control file:
 + "auto\n" to allow the device to be power managed at run time;
 + "on\n" to prevent the device from being power managed;
 The default for all devices is "auto", which means that they may
 be subject to automatic power management, depending on their
 drivers. Changing this attribute to "on" prevents the driver
 from power managing the device at run time. Doing that while
 the device is suspended causes it to be woken up.

    Pour les Nvidia Optimus c'est effectivement Bumblebee et bbswitch mais je doute que cela fonctionne vraiment avec une Nvidia classique.
