[CONFIGURATION] SDDM Not writable

[Franck]

Hello
When starting my session before the step of entering my password, a window appears.
Configuration file */var/lib/sddm/.config/sddm-greeterrc" not writable
Please contact your system administrator
How can I fix this problem?

Try checking the directory ownership; it might have been set to be owned by root as opposed the the user sddm.

Try:

sudo chown -R sddm:sddm /var/lib/sddm/.config
