Nvidia drivers installed but card not outputting

[wneeley (Wil Neeley)]

I recently did a fresh install of fedora 32. When I went to install the drivers for my NVIDIA card the drivers installed fine but the graphics card is not outputting video. I installed the drivers with the following commands.

dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
dnf install https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
dnf install akmod-nvidia

When I open nvidia settings it shows both monitors as connected but they are not outputting video.

Only my AMD card is outputting video. But I am going to be passing the AMD card to a VM so I need the nvidia card to be used as main card for linux desktop.

What is the output of “xrandr” ?

Are you using an adapter between the video card and the monitor?

Sometime signal is sent to VGA port, even if the monitor is connected to HDMI or DisplayPort.

[wneeley (Wil Neeley)]

Nvidia Card only had HDMI and Displayport output. Both of which are connected to different monitors.

The AMD card is currently connected through displayport. However it has 3 Displayport outputs and 1 HDMI output.

Not using any adapters hooked up directly.

Ok… Frankly I am not used to this… and I would probably have asked for the output of “xrandr --listproviders” if I would. Which we hope will have 2 entries. I am in part following instructions from How to configure a second graphic card on Arch Linux or Debian 9 Stretch | by Authmane Terki | Medium . Also it suggest to verify detection of the cards with “ls /sys/class/drm/”.

So I fixed it by running

sudo X -configure
sudo nvidia-xconfig

I had to manually install nvidia-xconfig before I could run it

Good! Please mark your previous comment as the solution… will avoid people have to read it to know the problem is fixed.
