Description of problem: After updating mutter component I couldn't logon to the graphical.target. GDM wouldn't show up at all (in both X and Wayland) - startx doesn't work also. Version-Release number of selected component (if applicable): 3.23.2-2.fc26.x86_64 How reproducible: Always Steps to Reproduce: 1. dnf upgrade 2. reboot 3. Actual results: Only pointer is shown, and it stays there. No GDM, no Gnome. Expected results: GDM login screen shows. Additional info: If you require any specific information don't hesitate to ask.
Same here. Downgrade to mutter-3.23.1-2.fc26.x86_64 workarounded the problem.
