Created attachment 162816 [details] "whoops i broke the computer" SUMMARY I believe this is quite severe - unless a user knows how to toggle to a different virtual console (ctrl alt f1, f2, ...) then they may believe they "broke their computer". SDDM really needs a default/stable login screen that it can fall back to. STEPS TO REPRODUCE 1. Using plasma settings, set sddm login screen to C64-Classic-Fancy (I am not picking on this particular theme, though I will file a separate lower prio issue about themes in the selector) 2. Reboot (or restart X) OBSERVED RESULT End up on the screen shown in attachment with a large virtual keyboard and no UI. (For context this is a 34" monitor, so the keyboard size is absurd in any scenario.)

SDDM isn't a KDE project, so SDDM bugs are not tracked on KDE's bug tracker. I'm afraid you'll need to report this to the SDDM folks at https://github.com/sddm/sddm/issues. This does seem like a real issue since SDDM has a fallback theme that should be getting loaded here in the case where the theme is broken.
Filed in SDDM. Thanks
