I just got this laptop and the second monitor is clearly detected by Fedora, as the monitor layout popup pops up, but the monitor doesn't actually work.

I assume this to be an NVIDIA problem, but as I have no experience with NVIDIA-based issues, I thought I'd ask here.

Here's my system specs:

KDE Plasma Version: 6.4.3
KDE Frameworks Version: 6.16.0
Qt Version: 6.9.1
Kernel Version: 6.15.7-200.fc42.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 24 × Intel® Core™ Ultra 9 275HX
Memory: 32 GiB of RAM (30.8 GiB usable)
Graphics Processor: Intel® Graphics
Manufacturer: LENOVO
Product Name: 83LU
System Version: Legion Pro 5 16IAX10H

Side note - is it not detecting my GPU?

It's using your embedded GPU, not the Nvidia one. Depending on the laptop build, only some outputs work with both, or one or the other. Kind of a crapshoot.

On your terminal run nvidia-smi and see if you get some output. If not, your Nvidia card isn't being used. On Fedora, it should be pretty straightforward to install the drivers if you haven't done so yet.

I went through that guide and just disabling secure boot worked for me! Thanks so much!

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.
