Linux working in one monitor but not in the other

So, yesterday I was trying to install Fedora on a PC with an Nvidia graphics card, it is a bit old and it has an Intel CPU. Basically as soon as I booted the USB it went all weird like if it would be having a graphical glitch like going all rainbow in some parts and stop responding, I tried a few more times under a UEFI secure boot or something like that, and it kind of worked but only in a very small resolution and nothing had animations and so on. This was connected to a monitor via VGA.

Then I said, well, maybe it’s a Fedora thing, so I installed elementaryOS and moved the PC to other place where I have another monitor that has HDMI support, I installed it while being connected to that and I had no problem, so I thought, well, it must have been a Fedora thing. I moved the PC to the other place where it was going to be used, connected it to the VGA monitor and the same glitchy thing happened, even though everything was already installed. Mind you that Windows was being used before and it was connected through that same VGA port.

What can be causing this?

Could you share your linux-hardware.org link? Would probably help with debugging.

Is the VGA port on your dGPU or iGPU? I know Fedora uses Wayland by default – are you using wayland or X.org on elementary?

What’s your exact hardware?

Did you install with secure boot disabled?

Probably Nouveau issue. ⚠️

For installing Nvidia drivers on Fedora:

Or give Universal Blue a try, take the pain away:

Atomic desktops are cool.

Also available as Bazzite for 🎮:

Or Project Bluefin for 🖥️ dev:

ASUSTeK COMPUTER INC. P8H61-M LX3 R2.0 Intel i3-3220 (4) @ 3.300GHz NVIDIA GeForce GT 640 Rev. 2

That’s my hardware

I honestly rather not install nouveau since iknow it can cause issues and i wouldnt mind installing nvidias proprietary drivers if it makes it work since its not even for me

do you know if i should install the 470xx or the one just called nvidia drivers in the app store?

ill give it a try to the rest tho, thanks!

Are you using the legacy Nvidia drivers? They dropped support for the 600 series gpu, so you’ll need to make sure you’re using a driver version "470.something?
