Hi List,
So I updated both my Fedora laptops from 24 to 25, resulting in both booting into black screens with no login dialogs and no way of going into a console or looking at logs.
Both systems are very different. One is a Lenovo, built-in Intel graphics support and XFCE, the other is a Dell with a AMD Firepro M5100 graphics card running Cinnamon. Yet the result is the same. I assumed Wayland is at fault here, however I noticed both systems work fine if I boot with an older kernel:
kernel-4.8.6-300.fc25.x86_64 : works
kernel-4.8.8-300.fc25.x86_64 : nope
I had some trouble finding further info on this looking at various forums and mailing lists, hence my message here. Any insight appreciated.

Can you try editing /etc/gdm/custom.conf and uncommenting WaylandEnable=false as a diagnostic step?

Problem still occurs on a fresh install, and /etc/gdm/custom.conf doesn't actually exist. I guess only lightdm is installed by the Live distro. Will try on other system.

In this case, it's definitely not Wayland.

Good to know, thank you.

That's because gdm is the Gnome Display Manager and Xfce uses lightdm by default.

As hinted, the culprit appears to be lightdm. Switching to gdm fixes the problem.
