I emailed this issue as requested including bugreport: https://github.com/Bumblebee-Project/Bumblebee/wiki/Reporting-Issues
thought I would post it here too as the noise of the fan rings in my ears...

Distro:
Linux Mint 12

Kernel:
$ uname -a
Linux XG 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

Manufacturer and model:
Dell Inspiron 15R (N5110)
note:
the command mentioned here didnt work for me:
https://github.com/Bumblebee-Project/Bumblebee/wiki/Reporting-Issues

$ for keyword in baseboard-manufacturer baseboard-product-name baseboard-version system-manufacturer system-product-name system-version bios-vendor bios-version bios-release-date; do
printf "%-22s: " "$keyword";
sudo dmidecode -s "$keyword";
done

I upgraded to latest Bumblebee 3.0 stable via PPA through Update Manager. All went fine, then I run:

$ optirun firefox
Xlib: extension "GLX" missing on display ":8".

the clue to the problem I found here:
https://github.com/Bumblebee-Project/Bumblebee/wiki/Supported-drivers

I needed to do the following to make the LibGL work:

1. open as admin /etc/bumblebee/bumblebee.conf
2. edit line 22 so it reads
Driver=nvidia

then do the following, to be sure:

After installation, allow yourself to use Bumblebee (replace $USER by your username):

sudo usermod -a -G bumblebee $USER

Then, reboot.

Now I notice even though its running few degrees cooler, after a while - 5 minutes or so, when temp drops below 59 degrees - the fan starts to make intermittent whirring sound, then constant whirring very noisy, too noisy. I suspect Power Management features...

so I run as advised on bbswitch page:

the fan noise problem occurs with or without the ppa:ubuntu-x-swat/x-updates
the machine is too noisy to use...
any ideas how to fix??
