In 2020 a decision was made to use Wayland by default in Fedora KDE Plasma, arguing that most modern GPUs should work with it without any problems, however I consider this a completely questionable move, as it still takes time for Wayland in KDE Plasma to be brought to a point where they can be used on a regular basis and without any problems at all. Another problem is that the use of a default Wayland session in a live image of Fedora KDE Plasma leads to the fact that the installation itself on some hardware (I have an old hardware with a 700-series Nvidia graphics card, but you can still live) can be very problematic or impossible because of violations of the desktop environment itself. In my case, when I clicked on the application menu icon, it was as if a poltergeist invaded my computer and began to create chaos on the screen. The application icons were bouncing around and then later on the screen went gray and everything froze. Further interaction was impossible. In the live image of Fedora Workstation I do not see such problems and everything works as it should and the installation took place without any problems.

I hope that KDE will make sure that the X11 session in Fedora KDE Plasma is used in order to avoid any installation problems until the Wayland session for KDE Plasma is brought to a sane state. And yes, I used Basic Graphic Mode, which is what the official Fedora documentation advises for GPU problems, but in my case it did not solve my problem.
