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

Output from lspci:

Code:

$ lspci | grep VGA 00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Trinity [Radeon HD 7600G] 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mars [Radeon HD 8730M]

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.
