No Greeterrc file


After changing from Fedora Manjaro was working dual boot using rEFInd but it hangs with:

Configuration file “/var/lib/sddm/.config/sddm-greeterrc” not writable …
The file is not there!
If I cancel the warning, rEFInd boots OK
Do I need SDDM if not how can I stop the warning?
Thank for your time
