Optiplex 7010, enable both onboard GPU and discrete GPU
I have an Optiplex 7010 with an integrated Intel GPU (4000) that so far I have not been able to run while also running a discrete video card. I have upgraded the Power Supply so I am able to run a compact GTX 1060 with no problems. I participate in the distributed processing network BOINC. Several of the projects will use the older Intel integrated GPU's to do part of their (faster than CPU) processing. In fact, that is what the GTX 1060 is doing. I can actually get the Intel GPU to both drive a monitor and to process BOINC project tasks. What I have not been able to do is get the both GPU's to run at the same time. I have the latest BIO's installed. I have tried every video combination in the bios (automatic, Intel, Nvidia). I have tried deleting/uninstalling the GTX 1060 drivers. But unless I remove the GTX 1060 from its slot on the motherboard, the Intel GPU doesn't "wake up". This is not a "have to" or any kind of disaster. I just would like to take "full advantage" if I can of "all" my hardware. :)
Any ideas?
Thank you.

It is not possible. A discrete card automatically disables the on board video.

Isn't there a way to enable it in the bios

I have an Optiplex 3060 and a currently have my CRT plugged into my onboard Displayport and two other monitors connected to my GTX 1060 6GB (Full size with PCI 6pin rail and two fans)
I'm running Windows 10 x64 and all I did was install the nvidia graphics driver. Either set of monitors is adjusted by whichever card has the thing connected to, but there is some default setting in the control panel to enable the other monitors.
This is my first modern computer in 10 years, so I'm missing a lot of changes since XP or Vista 32 bit.

It's a shame that Dell decided to cripple this machine in this way. No access to Quicksync while using a dgpu is very unfortunate for such a nice machine. This is a big plus for team HP in my opinion.

The Optiplex comes in MT, DT, SFF, and uSFF versions, though there is no PCIe slot for a GPU in the uSFF version.
I have the SFF version and after much fighting was finally able to get both the iGPU and a PCIe GPU to both be recognized and work with the OS. Unfortunately this requires re-fighting if the BIOS settings are lost or PCIe devices are changed.
In order for it to work, I needed to have the PCIe GPU installed (RX6400 in my case, as the PCIe3x16 slot can only handle a 50W card in the SFF version) and at least 2 different displays connected (at least one to each GPU) while booting. During the first 'config' boot, the 7010 seems to reboot a few times to discover the connected devices and afterwards I enter BIOS setup, select the Intel HD as the primary video and do NOT enable the Win7/8 multi-monitor setup as that confusingly disables the video out of the PCIe GPU and routes it all through the iGPU (motherboard video ports only). Once booted into the OS, I can setup my actual primary display on the PCIe GPU and leave the iGPU display disabled/unconfigured. After this first boot and configuration, it can boot and reboot without the iGPU display connected and still have the iGPU enabled for quicksync hardware encoding/decoding.

I was WRONG. There must always be at least one display attached to the iGPU during boot and it set as the primary within the BIOS settings to not disable the iGPU. Multi-monitor setting seems to have no effect regardless of any other settings combinations.
Two conditions to enable both iGPU and dGPU:
* different monitors connected to each one (gpu is disabled if no display attached at boot, true for both for iGPU AND for dGPU)
* iGPU set as default for boot (if dGPU is set as default, iGPU is disabled, regardless if monitor is attached)
I found this chart which also shows that iGPU must be primary:

The good thing is once the OS is booted, any display can be disabled and any display can be set as the primary, such as the actual primary display on the dGPU.
