Πίνακας Περιεχομένων
xfce4-session is a session manager for Xfce 4. Its task is to save the state of
your desktop (opened applications and their location) and restore it during a next
startup. You can create several different sessions and choose one of them on
startup.
xfce4-session provides session management for both X11R6 and
legacy X11R5 protocols. If you don't need legacy session management
support, you can disable it at compile time, giving
--disable-legacy-sm to ./configure. Do NOT EVER run smproxy in
session that is managed by xfce4-session, or weird things will happen.
The included legacy session management does everything that smproxy
would do, and besides that, it also supports multiscreen display.
- Display chooser on login
If set, the session manager will ask you to choose a session every time you log in to Xfce.
- Automatically save session on logout
This option instructs the session manager to save the current session automatically when you log out. If you don't select this option you'll be prompted whether you want to save the current session on each logout.
- Prompt on logout
This option disables the logout confirmation dialog. Whether the session will be saved or not depends on whether you enabled the automatic saving of sessions on logout or not.
- Launch Gnome services on startup
Enable this option if you need the GNOME keyring daemon to be run on startup. This option also instructs
xfce4-sessionto bring up the GNOME assistive technologies at startup (if enabled in the GNOME control center). See the GNOME documentation for more information on this topic.- Launch KDE services on startup
Enable this option if you plan to run KDE applications as part of your Xfce Desktop session. This will notably increase the startup time, but on the other hand, KDE applications will startup faster. Some KDE applications may not work at all if you don't enable this option.
- Manage remote applications
Allow the session manager to manage applications running on remote hosts. Since this option may constitute a security risk, by listening to a TCP port on your system, do not enable it unless you know what you are doing.
System administrators may want to disable this option globally using the session managers KIOSK capabilities.
You can customize the splash-screen that xfce4-session will use when you log in to
Xfce 4. There is a dedicated dialog available from the Xfce 4
Settings Manager.
On the left, the dialog shows a list of all installed engines. Select an engine, and you will see, if available, a preview and information about it. You can click on the button to see a demonstration of the selected splash screen engine.
xfce4-session provides three Splash themes engines by default. Their
respective configuration options - if any - are available from the
button.
xfce4-session supports shutting down your computer when you log out
of your desktop session. To be able to shutdown the computer, you
have to be listed in the systems sudoers file,
in particular, you must be allowed to execute the command
${libdir}/xfce4/session/xfsm-shutdown-helper
(/usr/sbin/xfsm-shutdown-helper on Debian GNU/Linux)
as user root (where ${libdir} is the lib sub directory in the prefix you
installed xfce4-session, for example
/usr/local/lib/xfce4/session).
For example, lets say, you installed xfce4-session into /usr/local, your hostname is myhost
and your user account is named myuser, then you
would have to add the following line to your sudoers
file (remember to use visudo to edit
that file):
myuser myhost=/usr/local/lib/xfce4/session/xfsm-shutdown-helper
Xfce now uses the Basedir Specification as defined on Freedesktop.org to locate its data and configuration files. This means that file locations will be specified as a path relative to the directories described in the specification.
- ${XDG_CONFIG_HOME}
The first base directory to look for configuration files. By default this is set to
~/.config/.- ${XDG_CONFIG_DIRS}
A list of system directories that contain configuration data. By default the panel will look in
${sysconfdir}/xdg/and/etc/xdg/. The value of ${sysconfdir} depends on how the program was build and will often be/etc/for binary packages.- ${XDG_CACHE_HOME}
Specifies the root for all user-specific cache data. If this environment variable is unset, it defaults to
~/.cache.- ${XDG_CONFIG_DIRS}/autostart/
This is the location where the list of applications that should be automatically run on login is stored. Each autostarted application is represented by a
