Fedora upgrade 42 to 43 stuck on boot due gdm/Wayland configuration

 

After upgrading Fedora 42 to 43, the system boot hangs on a log line indicating that the virtqemud.service service had started correctly.
I only then noticed a more relevant message: the GDM service had started correctly.

Enabling debug logging could have help me save time. Anyway, the solution is to open a new TTY with Ctrl+Alt+F2 and comment WaylandEnable=false in /etc/gdm/custom.config .

Fedora uses Wayland as its default display server, and for Fedora 43 and newer, it has become the only desktop session for the default GNOME desktop, meaning X11 is no longer supported for that session.
