The reason you can't turn it off from the bios is likely because that isn't possible. There obviously aren't separate video out ports for each device. My understanding of how this works is that the better GPU (AMD in this case) is used for 3D rendering to a buffer and then that buffer is copied into the other (Intel) device for outputting to the display. If you blacklist the i915, you will have no graphics at all.
You might be right.
My question to the OP is why do you want to do this?
Because I want to actually use the hardware that I have.
So if you really do need that for something, use the right-click menu option.
There is no way to verify that the card is being used. If you could just help me to verify that the card is actually used or not then this whole problem would be solved.
Is there any way to verify this? Any application I run that wouldn't run on the Integrated Graphics but would run on the discrete card ?
