XPS 8950, Intel iGPU disabled after BIOS update

Do you also have a video card installed?

I do have a discrete NVIDIA GPU, yes. This one works fine but I need to work with both. I am running compute workloads with CUDA and oneAPI Level Zero. Until recently, both were working, so I am not sure this was due to a system update. Any idea? 

Dell’s bad. Original service manual mentions Multi Display option in bios, but user reports this option is removed, likely of the new bios version.  The fact they furtively remove options without public explanation or disclosure is not user friendly.

I rolled back to BIOS 1.4.0 (July 2022) and the same issue happens (Intel Integrated GPU is disabled)

Then I tried BIOS 1.3.0 (June 2022) and the Intel Integrated GPU is visible as well as the NVIDIA GPU. Level Zero and OpenCL work again. 

I am not sure the reasons behind this decision (energy? security?), but if I am forcing the GPU to be enabled, this is what should happen. Takeaway: do not update the BIOS if you want access to the Intel UHD Graphics and stay with version 1.3.0 for the XPS 8950.

DELL, this is totally unacceptable without any notice. 

I believe that the option is listed under "Advanced Power Options" in the BIOS and it is called something to the effect of multiple displays(I don't remember exactly what it was called but make sure it is enabled). My 8950 did the same thing and in device manager under "Display Adapters" Intel 770 was not listed. In device manager I selected view - show hidden devices and then it came up but it said it wasn't working correctly. I uninstalled it from device manager then hooked up a second monitor to the integrated DP and restarted the PC. It worked after that. That was about a week ago and I have not tried it again, I just wanted to make sure that I could use the integrated graphics if I needed to.

8950 bios old versions: 

user annoyed3 reports bios version 1.0.13 has the Multi-Display option.

With a dedicated Nvidia card installed, you should only be using the Nvidia card.

If you want to test software on Intel-IGP, try a different machine (maybe an desktop or UltraBook with only that).

I have the integrated and discrete Nvidia graphics working on my 8950 with the newest BIOS 1.5.

nice.  does bios 1.5 offer multi display somewhere?  if yes can you upload a screenshot of that to help other users?

It is in the 1.5 BIOS >>>>>>>>ADVANCED>>>>>>>POWER OPTIONS>>>>>>>>INTEL MULTI DISPLAY( Or something to that effect).  I am not at home to look it up on my desk top. It is like the 2nd or 3rd option from the bottom in the advanced tab listed with the power options.....the same place that the USB power options are.

ok. I had a friend send some pics...almost as good as screen shots......

Hi, I was able to enable the integrated video in the uefi.  However, it does not show in device manager.  Any ideas?

Yes, thanks.  Shows up as Microsoft Basic Adapter.  Trying to update to Intel driver does not work.  

Again thanks,

In device manager, if you go to the view tab and select show hidden devices, does it show up then?

It does show up in device manager with this.

Currently, this hardware device is not connected to the computer. (Code 45)

To fix this problem, reconnect this hardware device to the computer.
