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

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!

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.
