1. Use “ck-list-sessions” command to check a seat is got or not.

2. Check the permission, owner and group of the “dbus-daemon-launch-helper”. (In BLFS 7.7, the location of this program is “/usr/libexec/”.

The correct setting should be:

The permission: -rwsr-x---

The owner: root

The group: messagebus

Fix the owner and group:

chown root.messagebus dbus-daemon-launch-helper

Fix the permission:

chmod 4750 dbus-daemon-launch-helper
