Utilize APU + GPU at once

[Kuci]

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

I can use both, they work perfectly, but I can't use both at once.

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 use oclHashcat v1.00 beta 19

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