edit: never mind your using the fglrx driver now, and I don't think it uses the switcheroo thingy

When your use the catalyst driver there is no /sys/kernel/debug/vgaswitcheroo. The vgaswitcheroo is for the open source drivers intel/radeon only, With the catalyst the driver is called fglrx. Some prefer the catalyst driver while others prefer the open source drivers. what one prefers has mostly to do is what works best for their system and if they are a gamer or not. The distros that run the most current kernels/xorg server tend to have less issues with hybrid graphics. I have used both catatlyst and open source. I'm not a gamer and due to problems with the catalyst driver during major updates of some distros I prefer open source. Before kernel 3.16 (I think it was) I had to add the following entry
Code:

echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
into /etc/rc.local to turn off power to the discreet card on boot up to prevent heating problems. The newer kernels I don't have to do that anymore.
