I'm building an Ubuntu PC with the following components:

  • Intel i7-7700 CPU
  • NVIDIA 1080 Ti GTX GPU
  • MSI Z270 SLI motherboard. Has integrated graphics ports for HDMI and DVI.
  • Ubuntu 16.04 OS

I'm struggling to navigate the inter-dependent web of software/hardware relationships that need to fall into place to get this thing running. Namely, to get the GPU running it seems that I need to configure CUDA and it's drivers with the monitor running off of the motherboard's integrated graphics.

The challenge is that I cannot run the monitor from the integrated graphics port with the GPU in the PCI slot. I've tried enabling the multi display option in the BIOS. Here's what lspci returns. Note that the only VGA compatible controller is the GPU:

I've tried installing the Intel graphics driver using a .deb file and the install just quits.

I have tons more questions, but can anyone help me get over this first hurdle? Do I take the GPU out, run the machine off the card to install it's drivers and enable multiple monitor display before plugging the GPU back in and enabling CUDA? I need the GPU for machine learning and want to keep it away from anything related to the system's graphical display.

  • No, you don't need to change outputs. You can boot with nomodeset and then install the Nvidia drivers. Cuda isn't required. – user692175 Dec 5 '17 at 14:16
  • @MichaelBay Does booting with nomodeset create the same behavior as as nouveau.modeset=0? Because if so I'm already doing that from the GRUB (which I have to call up every time I boot) and getting the same results. – Aaron Dec 5 '17 at 19:35
  • Not exactly the same. Nomodeset forces VESA mode that is always compatible but in low graphics mode. It allows to install the required proprietary drivers though. – user692175 Dec 5 '17 at 19:39
  • @MichaelBay OK, so just nomodeset after the quiet splash line in the GRUB and from there I should be gtg for installing NVIDIA drivers. Question, though: can I use the GPU for computation and powering the monitor at the same time? It seems to me that I'm still going to want to switch the monitors to integrated graphics no matter what, right? – Aaron Dec 5 '17 at 19:53
  • If you have no multi-monitor setting (or it doesn't work) then you have to work with the Nvidia card only. – user692175 Dec 5 '17 at 21:33
