運行 KDE Frameworks 5、Plasma 5，用作sddm顯示管理器。
ConsoleKit並且PAM-linux都已安裝。
登入後（使用登入sddm畫面），ck-list-sessions返回FALSE和is-local。active僅存在一場會議。
如果我註銷，然後重新登錄，這兩個欄位都是TRUE，正如預期的那樣。
sddm不是支援 dm 的控制台套件。因此，我使用該pam_ck_connector.so模組來附加 consolekit 會話。
sddm 啟動檔 ( /usr/share/sddm/scripts/Xsession) 被修改為使用下列行啟動：
eval exec "ck-launch-session dbus-lauch --exit-with-session $session"
（我認為相關的）pam 檔如下：
/etc/pam.d/sddm:
auth include system-auth
account include system-account
password include system-password
session include system-session
session optional pam_loginuid.so
session optional pam_ck_connector.so nox11
session optional pam_warn.so
/etc/pam.d/sddm-greeter:
# Load environment from /etc/environment and ~/.pam_environment
auth required pam_env.so
# Always let the greeter start without authentication
auth required pam_permit.so
# No action required for account management
account required pam_permit.so
# Can't change password
password required pam_deny.so
# Setup session
session required pam_unix.so
#session optional pam_loginuid.so
session optional pam_ck_connector.so
session optional pam_warn.so
pam_warn.so已新增行以強制記錄到/var/log/auth.log檔案。典型的登入類似於：
<date/time> <pc-name> sddm-helper: pam_unix(sddm-greeter:session): session opened for user sddm by (uid=0)
<date/time> <pc-name> sddm-helper: pam_warn(sddm-greeter:session): function=[pam_sm_open_session] flags=0 service=[sddm-greeter] terminal=[:0] user=[sddm] ruser=[<unknown>] rhost=[<unknown>]

如何讓我的系統第一次正常啟動？
