I have followed http://ubuntuportal.com/2012/01/bumblebee-3-0-tumblewed-nvidia-optimus-gpu-switching-for-linux-has-been-released-how-to-install-bumblebee-3-0-on-ubuntu.html this guide to install nvidia driver on my Dell Inspiron N5110 notebook (Intel HD Graphics 3000 + NVIDIA GeForce GT525M), but i always get some error while i want to start any program with the optirun command.

Terminal says:

adam@Adam-LT:~$ optirun firefox [ 1482.559417] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver

[ 1482.559517] [ERROR]Aborting because fallback start is disabled.

My laptop cooler always cools the laptop, which means that nvidia card is consuming power in the background. (Terminal sometimes says something daemon-server is not running.) Can you give me some solution for this?

I've seen this problem reported under several questions, but I haven't been able to resolve any of it so I thought I'd bring it all in under one umbrella.
