Screen locker broken.

Wed Apr 04, 2018 1:54 pm
I'm a tech lead for a company and working on standardizing our operating systems for Ubuntu and Fedora. We're using Neon for the KDE / Ubuntu setup, we also have KDE / Fedora machines which are not experiencing this issue. Does anyone have any experience with this error, and a solution? Thank you in advance.

This can happen when kde plasma is updated while running. The solution is just to restart the p/c.
