This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

    
Have you enabled any additional drivers via Jockey (The additional drivers GUI)? –  adempewolff May 31 '12 at 16:17

In case you are still getting low resolution you should delete Xorg.conf file

$ sudo rm /etc/X11/Xorg.conf

While following this procedure it is better you should not start X server

Instead login through text mode. To login to text mode use the following

$ sudo vi /etc/default/grub

Change GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="text" and $ sudo update-grub

After installing nvidia-current and bumblebee, revert the changes in /etc/default/grub to login into graphical mode.

If you have hybrid graphics and installed the nvidia-drivers without bumblebee you are in for a lot of touble! Just kidding...

Remove the nvidia proprietary drivers either by sudo apt-get autoremove --purge nvidia* or through synaptic (if you have it installed) then reboot.

Now:

follow the instructions on this wiki about how to properly install bublebee with nvidia drivers and enjoy your laptop to its fulliest!
