Hey,

from the logs the problem is that the greeter cannot connect to the socket.
" Socket error:  "QLocalSocket::connectToServer: Invalid name"
Cannot connect to the daemon - is it running?"

You can see the socketname in the logs /tmp/sddm-:0-ffVDPB
Tht is the same as in the normal-sddm.log - so it seems like this socket stays 
alave while you are logged in. Is this the case?
Does restart sddm service helps? (as root: systemctl restart sddm.service)
Maybe LXQT does not finish its session fast enough and some thing is still 
dangling around.  ( search for processes that are created by you user)
Do you know that a previous version of sddm that worked?
Do you use systemd and loginctl?

Regards,

hefee
