I know that you and I cannot be alone in this problem. Its "good" to see that I'm not the only one with this headache. Sorry to see your going through it as well.
See in my case I cant even run the cable out of my HD6950 to the monitor...all I get is a black screen.
I also went into BIOS ans wondered whateffect changing the Intergrated graphics to forfce might have, I havent tried that yet but maybe its worth a shot to see if it would allow me to connect the discrete card to my monitor.
I was just reading about the AMD Vision Control Center (seeing that version 13.4 was releazsed last week. I havent tried installing it yet but am going to try that this evening and see what happenens. In the meantime I compklete removed the AMD Vision Control Center (via basic uninstall).
I am now wondering if the options that show up for ENABLE and DISABLE DUAL GRAPHICS under the PERFORMANCE header in AMD Vision Control Center only appear ....IF you have a discrete card that the iGPU recognizes as able to crossfire with it.
In both your case and mine the A10 at the very least is supposed to be able to swithchg back and forth as the computer decides which GPU is best suited for a particula task.
I'm also in the same boat as you naptown ...if I need to just abandon the idea of the swithing back and forth thing...so be it. My HD6950 will do the job as my computer is 90%...just for gaming.
Trouble is you can't find any clear cut explanation anywhere that tells you how to disable just the iGPU aspct of the A10. Its not like you would want to uninstall the drivers for the iGPU as someone has already suggested to me.
Even if I first disable the iGPU then restart the computer, swap over the monitor cable to the HD6950 and restart it... all I get is a black screen....So although the computer is telling me the discret card is working properly (prior to shutting it off and re-booting), something is very wrong. (I'm then stuck having to physically pul the 6950 out of the case and restart the computer. The computer then automatically re-activates the iGPU and the video is back.
I think that this is the actual problem in a nut shell. The iGPU is always allowed to re-activate itself upon restart (even if you click- disable driver --before shutting off the computer). If as you said, we can figure out how to "perminately" disable the iGPU itself...I think we will have solved the problem.
I'm guessing that both your GPU's are also showing up like mine "This device is working properly" .... meaning if you go under SYSTEM INFORMATION then DEVICE MANAGER and then DISPALY ADAPTERS.
In my case and yours LIKELY as well...both GPU's will be listed and when you check on their individual status, it shows both are functioning properly.
Hopefully some others will help us out, by jumping in on this discussion. In the meanwhile I post anything I can figure out and come up with.
I'm guessing your 7950 is doing exactly the same thing my 6950 is doing..that being working with the iGPU in a dual graphics mode...yet not in crossfire...since neither of us are using the 6670 or 6570 (which would support dual graphic combination with A10.
I think I will try to do what you did with a FORCE BIOS setting and see if it allows my monitor cable to attach to the discrete card as your is allowing. Other than that, I think out problem is identical.
Are you now running AMD Vision Control Center (version 13.4)?
