Description of problem:

I have one of those clever 'hybrid graphics' laptops that are designed to use
an integrated graphics card for everyday stuff, and switch automatically to a
more powerful discrete card for more graphics-intensive uses. However, under
Fedora the discrete graphics card is never used - I appear to be stuck with the
integrated card at all times. Though I always suspected it, I didn't know how
to check which card was being used until I ran a few tests from the Phoronix
Test Suite - the test results indicated that only the integrated card had been
used. The tests simulate the playing of graphics-intensive games, a use case
which should in theory activate my discrete card.

I tried using David Airlie's 'switcheroo' fix, as described here:
http://linux-hybrid-graphics.blogspot.com/2010/07/using-acpicall-module-to-switch-onoff.html

However, the fix didn't work for me. I noticed that most of the users who were
reporting success with switcheroo were using hybrid setups with an Intel
integrated card and an NVIDIA discrete one, whereas mine are both AMD/ATI
(Radeon 3200HD and 3450HD, respectively).

While I'm not a heavy gamer, this problem leaves me unable to do the things a
discrete graphics card is supposed to allow you to do, such as edit
high-quality video, or even make a Skype video call without glitches.

How reproducible:
Not quite sure how to do this! I suppose one way would be to run the Phoronix
Test Suite.

Steps to Reproduce:
1. Install Phoronix Test Suite on a machine with a hybrid AMD/AMD graphics
setup
2. Run a graphics-intensive test, such as the OpenArena test
3. Check the results to see what graphics card has been used

Actual results:
The test reports that the integrated graphics card has been used.

Expected results:
When the test is started, the laptop should switch to using the discrete
graphics card.

Additional info:
Actually, automatic switching would be a luxury - I'd settle for a way to
manually toggle between the two cards. Or even some way to permanently switch
to the discrete card - the laptop's battery life is already abysmal and I never
use it away from my desk anyway!
