I am trying to configure dual monitors on a custom built machine with an Intel i7-7700K CPU, a NVIDIA 1080-Ti GPU, and a CentOS 7 operating system. I have no problem booting with the primary monitor connected to the DVI port, but activating the secondary monitor with the HDMI port has been a struggle. After reading this post I tried updating the /etc/X11/xorg.conf for the GPU with the following lines:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BusID "PCI:01:00:0"
    Option "NoLogo" "true"
    Option "UseEDID" "true"
    Option "ConnectedMonitor" "DFP"
EndSection

I did not reboot the computer at this point. Just saved the file and switched the power on the secondary display on and off.

This post also points to xorg.conf as being part of the solution, but so far I haven't had any luck. I've opened up my displays panel and only my primary monitor is being detected. In case it's relevant information, I have also installed all NVIDIA drivers and configured CUDA on this build.

Any thoughts? How do I get this secondary monitor up and running?

Open a command terminal and then run 'sudo nvidia-settings' . This should open up the nvidia setup application where you can fix your video settings to support multiple monitors and then reboot and you should be up and running.

  • I switched to Fedora awhile back so I haven't had the chance to try this, but I'm upvoting it because it seems reasonable. Thanks for the time! – aaron Apr 15 '19 at 16:58
