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.

I'm fairly new to Fedora, so I don't know much (yet), I'm still learning.

That said, I tried upgrading from Fedora 38 to Fedora 39, it worked perfectly, I updated everything (including the NVIDIA drivers, yes) and everything was running fine, I did not delete the previous versions of Fedora from my laptop just in case.

Come today, a week later, and I can't enter Fedora 39. My laptop gives me a list of OS to choose from: Fedora 39, Fedora 38, and (sadly, because I need it for my job) Windows.

When I enter Fedora 39, there is just a black screen and the laptop doesn't proceed from there, however, when I choose Fedora 38 (or W11), I can enter without any issues.

So now the TL;DR:

Having Fedora 39 already installed, is there any way I can uninstall Fedora 39 completely while being on Fedora 38, and then reinstall? If so, how would I do it?

Thanks in advance for the help!

The options when you boot are the kernel versions not the Fedora version. You’re not booting into Fedora 38, you’re booting Fedora 39 with a 38 kernel.

There’s nothing wrong with using a Fedora 38 kernel on 39 if it works. There’s probably a kernel bug affecting your computer in the current 39 kernel that’s making it not work

The easiest solution will be to wait for a new kernel and hope it fixes this bug

Sorry for my ignorance, but how does that work? I (think) I understand what a kernel is, but how am I using Fedora 39 with a 38 kernel? Is there a documentation I can read somewhere so I can understand how that works?

Today it got fixed somehow, I just booted up Fedora 39 and it just worked. Also thanks a lot for the answer!

When booted in fedora 39, maybe enter the console and try to start X manually to see why it fails

They mean use the CTRL+ALT+num key combos to get a TTY. Google to figure out which Fedora uses.

First link I found explained it: https://www.dhiller.de/2020/02/13/switch-to-console-on-fedora.html

Starx only works for X11. Wayland Desktops have different implementations like startplasma-wayland

Fedora uses wayland
