From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

[Fedora] [Nvidia] Fresh install, DisplayPort monitor not recognized (sh.itjust.works)

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.

Under the no-picture item it says to check whether the PC supports standard DP 1.4, and if it doesn't, to set Menu > System > DisplayPort Ver. to 1.2 or 1.1 and reconnect the cable. The menus are probably different between the Neo and OLED models.

Your '-1' comes from the Intel driver, where modeset is an integer and -1 means the driver default. OP has an RTX 5070 Ti, and 'nvidia_drm' modeset is a boolean, so '/sys/module/nvidia_drm/parameters/modeset' reads 'Y' or 'N'. Files under '/sys/module/*/parameters' show the value the loaded module is running with.
