Hey everyone! I'm new to the Linux world and just installed Fedora 42 with KDE Plasma today. Initially, everything seemed to run perfectly, but then my monitor started flickering after a couple of hours. It keeps turning off and on repeatedly. I noticed that when I'm on the login screen, the display is fine, but as soon as I log in by entering my password, the flickering starts again. Has anyone run into this issue? If so, how did you manage to fix it? Thank you for your help!

Have you tried changing the display protocol? If you're using an Nvidia GPU, it might be worth switching from Wayland to X11. Just check the SDDM settings for session behavior and set it to X11, then reboot. You can verify what protocol you're using with `echo $XDG_SESSION_TYPE`. Just a heads-up, they might remove X11 in future Fedora releases, so keep that in mind!
What kind of Nvidia GPU do you have? If it's an older model, it might not play nicely with Wayland. Switching to X11 could definitely help.
