Bumblebee problem: nvidia module loaded on start up

Hello,

i have an ASUS UX32VD notebook with an intel and nvidia graphics chip.
Since a few days the internal nvidia card isn't disabled during startup, but i don't know whats wrong... here's the console output where you can see whats happening:

[root@UX32VD /]# cat /proc/acpi/bbswitch 
0000:01:00.0 ON

[root@UX32VD /]# tee /proc/acpi/bbswitch <<<OFF
OFF

[root@UX32VD /]# cat /proc/acpi/bbswitch 
0000:01:00.0 ON

[root@UX32VD /]# dmesg | grep bbswitch

[root@UX32VD /]# cat /etc/modprobe.d/disable_nvidia.conf 
blacklist nvidia

[root@UX32VD /]# cat /etc/modprobe.d/nouveau_blacklist.conf 
blacklist nouveau

[root@UX32VD /]# systemctl status bumblebeed.service

[root@UX32VD /]# rmmod nvidia 
[root@UX32VD /]# tee /proc/acpi/bbswitch <<<OFF

[root@UX32VD /]# cat /proc/acpi/bbswitch

why is the nvidia module loaded? it is blacklistet and bbswitch disables the card during startup...

Hi,
I had the same problem on an ASUS N56VJ, but I didn't blacklist it like you. I'm not sure why it would continue to load while it's blacklisted, but I tried something else that seemed to work.
In my case, I added the bbswitch module into the initramfs so it loaded before the nvidia module and that fixed the problem.

It's probably not the best solution, but it's the only one that I've used that works.

What kernel version are you using?
There is an open issue with 3.8 kernel.

I'm using the recent 3.7 kernel.
Deleting the blacklist files and adding bbswitch to the mkinitcpio didn't solve the problem :-/

How did you blacklist it?
EDIT: Saw first post.
If blacklisting isn't working, I'd assume the nvidia module was in the initramfs or something else is loading it.
You can try this which was pulled from the wiki:

Note: The blacklist command will blacklist a module so that it will not be loaded automatically, but the module may be loaded if another non-blacklisted module depends on it or if it is loaded manually.
However, there is a workaround for this behaviour; the install command instructs modprobe to run a custom command instead of inserting the module in the kernel as normal, so you can force the module to always fail loading with:
/etc/modprobe.d/blacklist.conf
...
install module_name /bin/false
...
This will effectively blacklist that module and any other that depends on it.
