Card never goes to power-saving mode
Hi,
On my system (Asus N56VB, with a integrated Intel card + Nvidia GeForce GT 740M), the Nvidia card is always active and never goes to power-saving mode.
This seems to be my problem: https://www.mail-archive.com/nouveau@lists.freedesktop.org/msg37804.html
If I disable the codec (echo '0000:01:00.1' > /sys/module/snd_hda_intel/drivers/pci\:snd_hda_intel/unbind
), the Nvidia card enters power-saving mode after a few seconds.
It however generally causes my system to become very unstable, going from not being able to start Steam, to causing full system lockups with the "nouveau" module locking up CPU 0.
