Turning off 1 out of 2 Radeon GPUs on Crossfire enabled HP Pavilion g6 2239-sr
 

Hello, I've read somewhere about that discrete GPU can be turned off in software in GNU/Linux.
I think the solution involved blacklisting nvidia graphics card driver, so that the device used the Intel integrated GPU.
Though admittedly i don't know if truly not loading driver disables hardware component, so please, don't limit yourselves to just providing a blacklisting driver solution in my case.
Perhaps there are better solutions?
However my laptop has 2 GPUs both from Radeon, but different architectures.
Is it possible to turn off my discrete GPU in order to reduce power usage and perhaps prolong battery life?

output for "xrandr --listproviders"

Code:

---

xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x8c cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 4 outputs: 3 associated providers: 0 name:ARUBA @ pci:0000:00:01.0
Provider 1: id: 0x55 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 6 outputs: 0 associated providers: 0 name:TURKS @ pci:0000:01:00.0

P.S. I can switch between my GPUs using the DRI_PRIME variable
