Fedora 39 not seeing second monitor

Ask Fedora
1

I’m currently trying to troubleshoot why I can’t get my fedora install to see my second monitor. I’m running the nouveau drivers on my GTX 770 card and both monitors display on the fedora live image when I boot into it, but not on my current install.

My current output from inxi -Fzxx is

Your GPU (GTX 770) was last supported by nvidia with the 470xx driver.

Booting from the live image probably uses the 6.5.6 kernel which was the release version kernel for F39.
I have seen some comments that the 470xx driver cannot be used on the 6.8.4 kernel but have no GPU to test that myself.

You may try the nvidia driver from rpmfusion by enabling the repo as noted here then installing the driver with sudo dnf install akmod-nvidia-470xx which will pull in all the packages needed to support that gpu.

After waiting 5 minutes following the install then reboot and the driver for that nvidia GPU may be loaded which should allow use of the second monitor.

NOTE however, that the nvidia 470 driver will not support wayland and you would only be able to use the X11 DE. This is another drawback to using the older hardware.

You should be able to upgrade that GPU in the desktop machine and then have a newer GPU that would support wayland with the newer drivers.

Almost the same issue here. Might be identical, depending on your setup. Fedora recognized my DisplayPort monitor, but not my HDMI monitor. It would not recognize any HDMI monitor in my testing. I downgraded the kernel to from 6.8.4 to 6.5.6 and all was well.

I ended up purchasing a newer GPU and ran into the exact same issue; however, swapping on the new card from using an HDMI output for one monitor and displayport for another to using displayport on both monitors solved the issue.

Moved to kernel version 6.8.5 and it also resolved the issue with HDMI.
