Utilize APU + GPU at once - Kuci - 09-28-2013

Hello guys, I have my new ASUS U38DT and it has APU with integrated Radeon HD 7600G and discrete GPU Radeon HD 8550. I can use both, they work perfectly, but I can't use both at once.

Now, the question is: Do you think that there is any way to utilize both GPUs at once ?

Here is my xorg.conf:

Code:
Section "ServerLayout"

    Identifier     "aticonfig Layout"

    Screen      0  "aticonfig-Screen[0]-0" 0 0

EndSection

Section "Module"

EndSection

Section "Monitor"

    Identifier   "aticonfig-Monitor[0]-0"

    Option        "VendorName" "ATI Proprietary Driver"

    Option        "ModelName" "Generic Autodetecting Monitor"

    Option        "DPMS" "true"

EndSection

Section "Device"

    Identifier  "aticonfig-Device[0]-0"

    Driver      "fglrx"

    BusID       "PCI:0:1:0"

EndSection

Section "Screen"

    Identifier "aticonfig-Screen[0]-0"

    Device     "aticonfig-Device[0]-0"

    Monitor    "aticonfig-Monitor[0]-0"

    DefaultDepth     24

    SubSection "Display"

        Viewport   0 0

        Depth     24

    EndSubSection

EndSection

Say what?

Have you tried running, say, oclhc-lite?
What does it say?

As far as I know, some notebooks disable the integrated gpu (in your case, it's the 7600G) when the discrete one is used.
You may have to dig into the power options.
Apart from that, I can't really give any useful advice.

I totally forgot about it. This seems to be the thing. I will check it out.
