You have to open the file as an administrator to be able to modify it. Open a terminal, type su <enter> your root password <enter> to connect as an administrator. Then to open the configuration file type : gedit /etc/bumblebee/bumblebee.conf

if i give "optirun glxgears -info" this is the answer:[ 241.540249] [ERROR]The Bumblebee daemon has not been started yet or the socket path /var/run/bumblebee.socket was incorrect. [ 241.540310] [ERROR]Could not connect to bumblebee daemon - is it running?

To check if the card is successfully disabled, type the command cat /proc/acpi/bbswitch. The result shoulf be ... OFF. It seems like in your case, the bumblebee deamon is not started yet.

1) Overheating issue

Your laptop seems to have two GPU (optimus technology) :

You need to use Bumblebee to desactivate the second GPU. To do so, follow the steps below :

2) Lack of brightness control

You can use a GNOME Shell extension to control the screen brightness when the keyboard shortcuts don't work : Brigtness Control.

If it doesn't work for you, maybe this blog post will help you a little bit. You can change the brightness in the BIOS when starting the computer (which is a work around not very convenient) or there are other methods that involve command lines (see the comments).

Let me know if you have issue installing and configuring Bumblebee.
