thanks for viewing.

I am dual-booting Ubuntu 14.04 LTS_x64 along Winodws 8.1_x64 with:

Processor: Intel Core i7-3635QM and Intel HD4000 integrated chip

AMD Radeon HD 8770M

In windows, the AMD switchable graphics program lets me choose which programs use which video card, but in Ubuntu it seems I can only download the catalyst control center which lets me choose which graphics card to use all the time unless I go and change it. I installed the fglrx package and then the fglrx-update, that didn't work so I had to install the lastest drivers for the AMD card straight from AMD's website. That lets me open the control center, is this the only thing I can get for Ubuntu? Is there any way that I can choose which programs use which card?

It should be possible with Catalyst Control Center:

enter image description here

To install open your Terminal and execute:

sudo apt-get install fglrx

Then give a restart.

If you have trouble setting up visit Ubuntu/AMD Binary Driver Guide

In a modern system (see here for more details), at least when using the open source radeon drivers, you should be able to use the environment variable DRI_PRIME. Check if it works by monitoring the difference between

DRI_PRIME=1 glxgears -info

and 

glxgears -info

I do not know if this thing is supposed to work with fglrx proprietary drivers.

If it works, you can add it to the .desktop file of the application you want to use the discrete GPU: Set variable in .desktop file

More info can be also found in Hybrid graphic card drivers (AMD® Radeon HD 8570 + Intel HD Graphics 4000), and, as ever, in the Arch Linux documentation pages.
