By default Ubuntu has selected the nouveau drivers as i have an nvidia gpu. But I need to run my system on the Intel GPU instead, with Intel drivers etc. How can I do this?

To achieve what you want, you will have to install the proprietary NVIDIA drivers and Optimus.
After that you can switch between the graphics from NVIDIA X Server Settings PRIME Profiles.
Assuming you have a NVIDIA GEFORCE 400 series adapter or newer execute these commands :

sudo apt-get update
sudo apt-get install nvidia-352 nvidia-prime
sudo reboot  

Update addressing your response to having problems with 352 drivers

Use another method - first uninstall the formerly installed NVIDIA drivers.
Highlight the Ubuntu entry in the GRUB boot menu and press the E key.
Add nouveau.modeset=0 to the end of the linux line - press F10 to boot.

On login screen press Ctrl+Alt+F1 - enter user name and password - execute :

sudo apt-get purge nvidia*  
sudo reboot  

Now install the NVIDIA drivers 358 from the Proprietary GPU Drivers PPA.
Highlight the Ubuntu entry in the GRUB boot menu and press the E key.
Add nouveau.modeset=0 to the end of the linux line - press F10 to boot.

On login screen press Ctrl+Alt+F1 - enter user name and password - execute :

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-358 nvidia-prime
sudo reboot

    he wants to use intel drivers. And he does not wants nvidia drives installed but want to switch to intel drivers – Edward Torvalds Dec 25 '15 at 11:49
  • I did exactly as above. same issue, attempting switching using prime-select doesn't work, still stuck on nvidia. Also, my nvidia control panel does not have PRIME Profiles – raaj Dec 25 '15 at 11:50
  • @edwardtorvalds : Then the only way to do this is to deactivate the NVIDIA card in BIOS ... in case this is possible ... otherwise you have to install the proprietary drivers. :) – cl-netbox Dec 25 '15 at 11:52
  • No i cannot do this. Could it be a driver issue? Perhaps if i downgrade from 352 to something lower prime profiles may work superuser.com/questions/998403/… – raaj Dec 25 '15 at 11:53
