==== Some of my applications are always started when I login ====
There are two possible reasons why the application is started: It is saved in the last session or it is listed in the auto started applications. Follow 1 of the two steps below to get rid of the applications.

  * Go to the Application Autostart tab ([[https://docs.xfce.org/xfce/xfce4-session/preferences#application_autostart]]) in the Session and Startup configuration applet and remove the application(s). You can also manually delete those files in ''~/Desktop/Autostart'' and ''~/.config/autostart''.
  * Most of the time closing all the applications and save your session when you logout is sufficient. If this doesn't work, remove the content of the ''~/.cache/sessions/'' directory when you're **not** logged in. And if you don't want xfce remember every session you should turn off (uncheck) "Automatically save session on logout" in Settings Manager -> Sessions and Startup (tab General)

==== I'm unable to shutdown or restart my computer when running Xfce. ====
There are two way to fix this: sudo and hal/dbus. Default starting from version 4.4 is hal.

== Using sudo ==
You have to allow the user(s) to execute ''<prefix>/libexec/xfsm-shutdown-helper'' with sudo. ''<prefix>/libexec/'' may be changed on your distribution, i.e. ''/usr/lib/xfce4/session/''. Install sudo and run ''visudo'' (root) and add the following line (replace prefix with the correct path):

   %users ALL = NOPASSWD:<prefix>/libexec/xfsm-shutdown-helper

Add the user to the ''users'' group (root):

   gpasswd -a <username> users

Add the user to the ''power'' group:

   gpasswd -a <username> power

When you logout and login again, the shutdown and restart buttons should be sensitive. For more information you can referrer to the xfce4-session and sudo documentation.

== Using hal and dbus ==
Make sure that the hal and dbus daemons are started on boot, and that you are running a recent version of dbus (at least 1.1). Refer to your distribution for exact steps.

In the steps below the groupname "**power**" is used. This is __DEPENDING ON YOUR DISTRIBUTION__.

Your /etc/dbus-1/system.d/hal.conf should contain a section similar to this:

  <policy group="power">
    <allow send_interface="org.freedesktop.Hal.Device.SystemPowerManagement"/>
    ...
  </policy>

Add the user to the ''power'' group (root):

   gpasswd -a <username> power

When you logout and login again, the shutdown and restart buttons should be sensitive.

==== I don't see the logout dialog when I press the quit button ====
Enable the checkbox "Prompt on logout" in the session manager settings.
