I’m trying to avoid creating a larger problem for myself, so I figured I’d call in help. Still fairly novice with Linux (especially Fedora), but I’m determined to finally migrate from Windows.
I’m running the XFCE spin of Fedora with a GeForce RTX 5070 Ti and Samsung Odyssey G9. I kept my Win11 partition during migration and confirmed the monitor setup still works in windows, just not Fedora. I’m currently typing this on my Fedora install, on a second monitor I set up to troubleshoot (HDMI on the 5070).
“rpm -qa | grep -i nvidia | sort” returns the following: akmod-nvidia-615.71.09-3.fc44.x86_64 kmod-nvidia-7.2.8-200.fc44.x86_64-615.71.09-3.fc44.x86_64 nvidia-gpu-firmware-20260916-1.fc44.noarch nvidia-modprobe-615.71.09-1.fc44.x86_64 nvidia-persistenced-615.71.09-1.fc44.x86_64 nvidia-settings-615.71.09-1.fc44.x86_64 xorg-x11-drv-nvidia-615.71.09-3.fc44.x86_64 xorg-x11-drv-nvidia-cuda-615.71.09-3.fc44.x86_64 xorg-x11-drv-nvidia-cuda-libs-615.71.09-3.fc44.x86_64 xorg-x11-drv-nvidia-kmodsrc-615.71.09-3.fc44.x86_64 xorg-x11-drv-nvidia-libs-615.71.09-3.fc44.x86_64 xorg-x11-drv-nvidia-power-615.71.09-3.fc44.x86_64 xorg-x11-drv-nvidia-xorg-libs-615.71.09-3.fc44.x86_64
“nvidia-smi” returns the following: NVIDIA-SMI 615.71.09 KMD Version: 615.71.09 CUDA UMD Version: 13.4
Did I mess something up in my install? I followed Fedora’s official instructions on Nvidia driver installation (sudo dnf install akmod-nvidia -y). As always, I appreciate the help. While frustrating as a start, I’m excited about making the leap.
Set the DisplayPort version in the G9’s on-screen menu to 1.2, replug the cable, and check whether
xrandrshows that DP output as connected.If it still shows disconnected, replug the cable and right after run:
sudo journalctl -k -b | grep -i -E 'nvidia|drm'Look for link training or EDID errors on that connector.
Also run
cat /sys/module/nvidia_drm/parameters/modesetand confirm it returnsY.Drafted with AI.
If you go into the thunderbolt control, have you approved the monitor?
Most of the issues with thunderbolt on Linux for me have been the insane/annoying approval process.
I can’t use gnome for example because the gnome login manager uses separate permissions so I can’t approve the display before logging in. (No idea if they fixed this).
On plasma there is a menu for this, but you may have to go into terminal or ssh into the machine, or use hdmi to enable your display then move your computer back to it.
ETA: here’s some articles that should work pretty much the same for Fedora
Isn’t thunderbolt different than displayport? According to the internet (again, no clue what I’m doing here), Fedora should auto detect and use displayport devices without needing intervention.
‘xrandr’ recognizes my GPU’s outputs correctly (1 HDMI, 3 DP), but erroneously states all displayports are disconnected.
