  The bug report is a  bit all over the place, and it started out as something different so disregard most of the posts there.
  
  I've been at this for some time and the core issue is that `kde_settings.conf` is not world-readable like `sddm.conf` is. The settings are being written but only SDDM can read them, no one else.
  
  By all accounts the `openConfig` variable in `sddmauthelper.cpp` should set `kde_settings.conf`'s permissions like it does for `sddm.conf`.
  
  I can get it to make `kde_settings.conf` world-readable if I remove the `!file.exists` check but what's mind-boggling is this still doesn't work when `advancedconfig.cpp` i.e. the Advanced tab is in charge of generating `kde_settings.conf` so even adding some code that would set the correct permissions if it detects wrong one wouldn't solve the issue 100%.
  
  I've also tried defining `kde_settings.conf` in `config.h` and CMake but that didn't help.
