Ubuntu, switcheroo

I'm getting pretty frustrate trying to get my laptop to switch graphics cards in Ubuntu.
I'm using this web page and the linked script (switch_between_cards.sh). Anyway, everything is fine, except the fact that

Code: 
/sys/kernel/debug/vgaswitcheroo/switch

doesn't exist.
In the webpage, it says to run

Code: 
grep -i switcheroo /boot/config-2.6.*

which outputs

Code: 
CONFIG_VGA_SWITCHEROO=y

makes me think that switcheroo is there to use

but when I run the check that they tell me:

Code: 
ls -l /sys/kernel/debug/vgaswitcheroo/switch

it can't the directory. It says the vgaswitcheroo is only active when the kernel is booted with "modeset=1" kernel option, so I tried putting "i915.modeset=1" in the /etc/default/grub file, but that doesn't do anything. I'm not quite sure what else to do. If anyone could help that would be awesome. If I can't turn off the dedicated graphics card, then it cuts my battery life in half.
 
Is this a nvidia card with optimus technology?
People have had a lot of issues with optimus. I'm not sure if it is fully supported yet.

Do you have catalyst installed?
Might be of some use:

and finally, see this thread to set up the acpi_call module to turn off the card.

hope you can piece it all together with this :D

I tried with and without Catalyst installed. I don't want to use acpi_call because that's really just to turn your card off. I'd like the function of switching between the 2. My only issue is that switcheroo isn't there. Though that second link may be able to help me out.
