Linux: The Ultimate Guide

Show selector on the login: Once set, the session manager will ask 
you to select a session each time you log in to xfce.
2. 
Automatically save session on the checkout: This option instructs 
the session manager to save the current session automatically when 
you log out.
3. 
Notify on exit: This option disables the checkbox exit. Whether the 
time will be saved or not depends on whether you enable automatic 
saving of exit sessions or not.
4. 
Kiosk mode: Session Manager provides Kiosk mode support, which 
helps prevent others from making changes to their session settings. 
To use it you have to edit or create a $ {sysconfdir} / xdg / xfce4 / 
kiosk / kioskrc file.
The way to define the format of this file is to use an example. The xfce4-
session section of your kioskrc file may look like this:
[xfce4-session]
CustomizeSplash = ALL
CustomizeChooser = ALL
CustomizeLogout = ALL
CustomizeCompatibility =% wheel
Turn off =% wheel
CustomizeSecurity = NO
It allows all users to change their splash, selector, and exit settings, but 
only allows users in the group wheel to customize the interaction and 
shutdown settings. No one will be allowed to adjust the security settings.
The session manager supports the following KIOSK capabilities:
• Customize Splash: The user to allowed to customize the splash 
screen.

• CustomChooser: It allows the user to customize the session selector 
settings.
• CustomizeGet Out: Whether the user is allowed or not to customize 
the opt-out settings.
• CustomizeCompatibility: Whether the user is allowed to customize 
the interaction settings (KDE/Gnome compat).
• CustomizeSecurity: Whether the user is allowed or not to make 
security settings. It is one of the MOST basic settings as it prevents 
users (actually libICE) from tying the TCP port.
• Shutdown: Whether the user can shutdown (restart or shutdown) 
the system, the restart options and the power off in the shutdown 
dialog will be gray if the user does not have this capability.
ConsoleKit
xfce Desktop requires a valid ConsoleKit session for it to work correctly. 
ConsoleKit is used for system actions such as shutdown, pause, and (un)
mounting devices (via Polkit for authorization). If you are using a desktop 
manager, DM will take care of that. For the console to start, this is slightly 
different.
When entering the console (without starting X), use the ck-list-sessions. 
Make sure it works = TRUE and local = TRUE. If not, check that the con-
solekit library is loaded with PAM.
At 4.10, start xfce with startxfce4 --with-ck-launch. It will start the 
xfce4-session with the ck-launch-session. At 4.10, the xfce4-session will 
oversee the launch of the dbus session.
Once xfce is launched, and you use ck-list-sessions, a second session 
is created that should give you all the necessary permissions to mount 
devices and use power actions (depending on each distribution, you may 
need to add them to different user groups).
Autostart Settings App
The applications can start automatically based on specific triggers, e.g., 
start a session, log out. You can add or remove apps. In addition, all appli-
cations with their desktop files stored in the user interface can be edited. 
When a saved session is restored, all resources from that backup session 
will be started in addition to the items selected in this list. Everything in 
italic font style is for a different desktop, but you can still enable it.

You can select when to start the action chosen in the drop-down menu. 
This allows you to use custom commands, e.g., exit, pause.
Thunar File Manager
It is the modern file manager of xfce Desktop Environment. Thunar is built 
from the ground up to be quick and easy to use. It is clean and intuitive 
and does not automatically include confusing or useless options. Thunar 
starts fast, and navigation in files and folders is fast and responsive.

ager options.

other improvements.
• UNIX File System: To understand the UNIX File System.
Thunar plugins can be installed as separate packages and extend Thunar 
functionality. Most Thunar plugins provide additional options for files in 
the context menu or shortcut. The interface used by thunar plugins is the 
thunarx API.
• Bulk Renamer: It can rename multiple files at once.
• Custom Actions: It can custom commands associated with com-
mon mime types or extensions.
