Second monitor not working on Fedora 42 (Solved) [RTX 4070Ti]

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!
