QFm is a QT-based file manager from Nick Battle (http://home.freeuk.com/nick.battle/). It allows you to browse local files and directories on the Thin Client in a graphical interface using the mouse rather than in a local shell using text commands. You can move, copy and rename files.

How to use QFm
Using QFm is similar to other file managers, such as Windows Explorer. You can delete, copy, rename and change files.
Tool tips help you through the basic features (holding the cursor over an object displays a short description).
To understand how files are displayed, the highest-level directory is root. Root contains a number of subdirectories, including setup, tmp, smb, nfs.
• setup Contains permanent files needed by applications, such as configuration files. The contents are not deleted upon boot.
• tmp Contains temporary files needed by applications for this session. Deleted upon boot. Note: Browser, ICA and SAP cache is stored here. For improved performance, we recommend reducing allocated cache in the respective program or, in the case of the browser, defining a network drive for storing program files (“browser home directory”). See “3.10 Browser Home Directory.”
• smb Displays the currently mapped SMB drives. Note: Only defined SMB drives that are currently mounted are displayed. The user must connect to the SMB drive before it will be displayed. For information on mapping SMB drives, see “3.9 Drives.”

While using QFm is intuitive, we provide the following general guidelines and tips:
• The task bar provides one-click access to the most frequently used commands: Home, Display hidden files, Exit, Refresh, One directory up, Change directory, Shell, New window.
• To expand a directory , click once. To display that directory only in tree view, double-click. To return to root, click Home in the task bar or File > Home.
• To open a file, double-click. By default, applications have been preset for the following files (you must have the respective application installed):
Acrobat Reader Opens *.pdf files.
Citrix ICA Client Opens *.ica files.
MP3 Player Opens *.mp3 files.
Opera, Mozilla, Firefox Opens HTML files.
QT Text Editor Opens *.cnf, *.conf, *.cpp, *.h, hosts, *.ini, *.java, *.log,
printcap, readme, *.txt files. See “4.8.8 Text Editor.”
Wav Player Opens *.wav files.
• You can bookmark frequently used files and directories by right-clicking on the file and selecting Bookmark. You can then jump directly to the file or directory using the
Bookmarks menu.
• To open a shell, click Shell in the task bar or File > Shell.
• The error “Not an executable file“ means that the file cannot be displayed. Try installing the appropriate software or clicking with the right mouse button on a file and selecting
Open with to display a list of available programs.
4.8.8 Text Editor
To use this feature, you must have the “Text Editor“ (qtt) package installed. It is in the package “Desktop tools“ (dtt) starting with version 1.4.2. In addition, base OS version 1.8.4 or later must be installed.
QT Text Editor is a simple QT-based text editor that offers basic editing features. You can copy, paste, find, undo, redo, select all text, etc. The files must be saved to the Thin Client or available on a network drive.

Click File > Open > smb, enter the network drive and click Open. This mounts the drive. It will then appear in the dialog box and can be selected. It remains mounted for the rest of the eLux NG session.

4.8.10 NoMachine
To use this feature, you must have the software “NxClient” (nxclient) installed.
NoMachine from Medialogic S.p.A. enables a UNIX workstation to provide terminal server functionalities. NoMachine software is based on the NX Distributed Computing Architecture, a suite of open source technologies built on SSH and the X-Window System. NX also translates and embeds the RDP (Remote Desktop Protocol) used by Microsoft in its terminal server product family and VNC protocols into X/NX. NX is faster than VNC or X11 and can run on bandwidth as narrow as 10 kBit/sec. It enables users to compress and accelerate remote desktops like Windows, KDE, Gnome and CDE. NX lets you work fluently even across slow links like modems.
NX software consists of the following components:
• NX server The NX server is available for Linux and Solaris and is licensed per-server, not per-connection.
• NX client The client software is available for eLux NG and other platforms. All NX clients are free of charge.
To configure the NoMachine NX client
From the Configuration tab, click New.
1. The Application Definition dialog box appears. Click the Local tab.
Name Enter an appropriate name for this application.
Application Click Customized.
Parameter Enter nx.sh.
Hidden Does not display the application in the Application tab.
Application Restart Click to select to immediately reconnect after the user logs off. When this feature is selected, the application automatically starts when the Thin Client starts or restarts.
Start automatically Click this check box to open the session when the terminal

From the Applications tab, double-click or use the Connect button to run the program.
How to use NX client
• The NoMachine NX server must be installed and running.
• A wizard appears the first time you run the software to help you through the initial configuration.
• For further information, see the NoMachine documentation available at
www.nomachine.com.
Tip
• We recommend setting the “cache on disk” (Configure > Advanced) to zero.

How to use the virtual keyboard
While using the virtual keyboard is intuitive, we provide the following general guidelines and tips:
www.myelux.com eLux®NG
• By default, the virtual keyboard program uses the keyboard language setting from the eLux NG starter (see “3.5 Mouse / Keyboard”), assuming the language is supported, otherwise English will be used. To manually set the language for this session or to view a list of available languages, click Main menu > Change Keyboard Layout.
Tip
• To set the size and/or position, enter the following command in the Parameter field: xvkbd.sh –geometry <width>x<height>+<x position>+<y position>
Examples:
xvkbd.sh –geometry 600x200 Set keyboard size to 600x200 pixel xvkbd.sh –geometry 600x200+200+0 Set keyboard size to 600x200 pixel and
position it above center
xvkbd.sh –geometry 600x200+0-40 Set keyboard size to 600x200 pixel and position it lower left
