systemctl disable kdm.service --forcesystemctl disable lightdm.service --forcesystemctl disable graphical.target --forcesystemctl disable plymouth.service --forceI did open another console. I couldn't see anything obvious. What are the tricks to finding a zombie process ?I let dnf update complete and it did, successfully. When I rebooted the main console wasn't completing to a login, so I knew something was up ! However I was able to get a login at a second console, so I did.
The graphical session never did boot for me, so I had no idea what login was being used, so I tried a few things.Then I did a bit of investigatingls -l /etc/systemd/system/display-
manager.serviceThis told me it was running sddm.so: systemctl- disable sddm.service followed by shutdown -r nowNow it boots to a command line and runs at a reasonable speed !I don't need a GUI right now anyway. I'll investigate further when I get some time.
