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 -- On Dienstag, 14.
