Comment 5 for bug 1265570

Hi Ferry,

It should be that when installing bumblebee it should install nvidia, but installing the nvidia drivers should not install bumblebee. Bumblebee is a 'hack' to get dual video cards working until nvidia supports it in their linux drivers. What bumblebee does is it stops the nvidia module (nvidia-331 in this case, hence why modprobing nvidia-331 and restarting x works) from loading at boot time, the kernel loads the intel driver only. Then when you use the optirun or primus commands it then loads the nvidia module and runs that application on the nvidia card. The whole point is not to load the nvidia module at all, until needed, to save power, using bbswitch-dkms package, I use bumblebee on my work laptop and hence why I was able to decipher the issue.

As you can imagine, since we don't have another video card on our setups, X bombs on loading because its configured to used the nvidia driver but bumblebee has stopped it from loading at boot time.

I suspect the packages dependency is wrong.
