[solved] Module bbswitch does not load, cannot disable nvidia

Question

Hey!
According to the title I'm unable to load the bbswitch module on load with it's given parameters. I do it the way suggest in the Arch Wiki.
I'm using linux-ck
local/linux-ck-corex 3.5.6-1 (ck-corex)
local/linux-ck-corex-headers 3.5.6-1 (ck-corex)
local/nvidia-ck-corex 304.51-2 (ck-corex)
(I heard theat graysky said that there are no problems)
My /etc/modprobe.d/bbswitch.conf looks like
options bbswitch load_state=0 unload_state=0
dmesg|tail -10 outputs:
[ 121.351475] bbswitch: version 0.4.2
[ 121.351486] bbswitch: Found integrated VGA device 0000:00:02.0: \_SB_.PCI0.GFX0

[ 135.343414] pci 0000:01:00.0: >power state changed by ACPI to D3
Any suggestions? Am I missing something? I'm thinking of adding bbswitch into modules-load.d and add the parameters as kernel parameters in grub but I'm not happy with that solution…
even if it's the "cleaner" version, imho.
Cheers!
Help is appreciated, thanks. :-)
Edit: If I load bbswitch manually, I have to restart bumblebee to turn the graphics off. I cannot disable the card via bbswitch suggested in bbswitch git repo with command: tee /proc/acpi/bbswitch <<<OFF.
Tried via modules-load.d now and grub boot parameters. The module is loaded but the card is turned on…
$domac.vex dmesg |tail -10

Added my bumblebee.conf _here_.

Hey Lekensteyn! First of all, thanks for your answer. :-)
I disabled the nvidia module now. My /etc/modprobe.d now looks like
/etc/modprobe.d
total 20K
drwxr-xr-x 2 root root 4.0K Oct 9 19:32 .
drwxr-xr-x 76 root root 4.0K Oct 9 12:49 ..
-rw-r--r-- 1 root root 45 Oct 9 19:32 bbswitch.conf
-rw-r--r-- 1 root root 18 Aug 8 20:08 nouveau_blacklist.conf
-rw-r--r-- 1 root root 17 Oct 9 12:23 nvidia_blacklist.conf
nvidia_blacklist.conf:
blacklist nvidia
nouveau_blacklist.conf:
blacklist nouveau
bbswitch.conf:
options bbswitch load_state=0 unload_state=0
There is only one more problem left… the bbswitch module does not load on startup. If I # modprobe bbswitch manually the nvidia card is turned off and it also seems the bumblebeed daemon is not started… I have no idea why. It worked with that setup all the time… not much has changed… imho nothing.
Are there any logs I could post or what can I do to eventually fix this problem.
Thanks for the help in advance!
EDIT: I can start the bumblebeed.service manually. + Why are the modules from modprobe.d not loaded? My mkinitcpio.conf.
EDIT2: Found it why bbswitch module wasn't loaded… http://comments.gmane.org/gmane.linux.a … eral/44986… testing this one right now.
