Expected Results: Should log in to XFCE After rebooting the machine, login to XFCE works. This is reproducible, logging in to Gnome again makes it again impossible to switch to XFCE without a reboot of the machine.
Problem still exists unchanged on Fedora 41.
By the way, on current rawhide, gdm does not even offer any Xorg desktops to log in even if these desktops are installed. To be able to use XFCE or Gnome Xorg on rawhide, I used lightdm instead of gdm: sudo dnf install lightdm sudo systemctl disable gdm --now sudo systemctl enable lightdm --now And then I can choose between all installed desktops, even the Xorg based ones.
