Cannot open login on SDDM display manager

[laidlaws]

This seems a bit spooky. I had been writing about an issue with Java, and had just installed the version from Oracle. Upon rebooting the SDDM Display Manager was no longer working. I could type into it, but upon hitting ENTER, the screen went black for a second or two, then the empty GUI returned. I could reach a console with the F1-F6 keys and type a password, but on trying to enter it, the same thing happened; the lines of text disappeared and I was back at the empty
prompt. I checked the permissions, but I have no idea what to try next.

I forgot to mention that I have the MATE desktop installed as well, and performance was no different

Dang.

was thinking you had a nearly full / partition, as your experience is a common symptom.

Have you tried booting to an earlier kernel?

[laidlaws]

A problem like that seemed more likely. This was a fresh installation. Windows had put partitions everywhere, and I had tried to squeeze Linux between them. I will try to rearrange them.
