Now working.

1-Downloaded nvidiabl debian base distributed version >>

2- Installed it dpkg -i nvidiabl-dkms_0.74_all.deb

3- Add module to /etc/modules

4- Download oBacklight Script >> (version 039 have an sh error try avoid it till is repaired).

5- Untar it tar -xvf oBacklight_0.3.8.tar.gz

6- cd to the untared directory

7-Give the script execution permission chmod +x oBacklight( I also change the owner and group to root but thats because im a little paranoid. You can avoid this.)

8-Copy oBacklight script to the /etc/init.d directory

9-Add it to the start up update-rc oBacklight defaults

NOTE: Depending on your laptop model, you may have to change the script mode. See >>

Ok now you're ready. In case you dont want to reboot now, just 'modprobe nvidiabl' and '/etc/init.d/oBacklight start' and test yourself.
