1 Introduction CAUTION: Thin clients are designed for remote data storage and excessive writes to flash may damage the flash memory. This guide provides the network administrator with instructions for configuration of the Linux-based thin client and explains the various configuration utilities. NOTE: Not all features described in this guide are available in all Linux-based terminal models.
Desktop options The following sections describe the Linux thin client desktops. The Linux desktop has a Windows-like look and feel. The desktop includes icons and a Start menu. By default, the following icons appear on the Desktop for the root (administrator) user: ● Home — Allows you to see a graphical representation of the files and folder on the system and allow for browsing of the various folders. ● Firefox — Allows you to launch an Internet Web browser.
ENWW 2. Select Backdrop. The Set backdrop window displays. 3. Click Show. The /usr/share/pixmaps/window displays. 4. Navigate to and select a .jpg or .png file 5. Click and drag the graphic file to the Set Backdrop window.
Taskbar The default taskbar contains the following icons that provide quick function access: Show Desktop — Displays the desktop. Window List Menu — Displays a list of available workspaces. XTerm — Accesses the terminal command window. The xterm program is a terminal emulator for the X Window System for programs that cannot use the window system directly. For more configuration options, type man xterm on the xterm command line. Mozilla Firefox — Opens the Firefox browser.
Synaptic Thin client software is organized into “packages”. The Synaptic desktop icon provides access to Synaptic Package Manager that allows you to easily add, upgrade, and remove packages to and from your thin client. Most applications reuse the functionality of other applications or libraries. Therefore, most packages depend on other packages. The Synaptic Package Manager resolves the dependencies automatically.
3. Type Y, and then press Enter. The install results display on-screen. 4. Read the installation results to confirm the packages successfully installed, and then close the window. NOTE: After running Synaptic for the first time, its icon changes.

74 Chapter 6 Frequently Asked Questions ENWW
7 Troubleshooting Altiris ISSUE Altiris fails to restore my Debian image from a USB storage device. SOLUTION This issue occurs with Altiris versions prior to 6.8.177. The issue does not occur with Altiris 6.8.177 or higher. Update to a more recent version of Altiris. HP Connection Administrator ISSUE Launching a connection changes the connection state to “active” then immediately back to “not connected” without establishing a connection. SOLUTION There can be a variety of reasons for this behavior.
SOLUTION When there is no existing /etc/.hpconman/wfclient.ini, cman will use the one created by wfcmgr, but there is an entry missing from the default wfclient.ini that only gets created after you enable it through wfcmgr. If you have already run cman, you need to remove the version without AllowAudioInput=True and enable audio in wfcmgr so cman will create a new version with the correct value.
System intermittently hangs while running Firefox 2.x. SOLUTION This occurs because the flash file system has no available space, which may be caused by the Firefox 2.x list of suspected forgery sites that are downloaded to the client by default. Try disabling this feature by clearing the Tell me if the site I’m visiting is a suspected forgery check box under Firefox 2.x > Tools > Security.
ISSUE You cannot print large jobs to local printers from an ICA session. SOLUTION The thin client has limited space available for the print spooler. This issue may occur if a large volume of documents or an individually large document is sent to the local printer. Try to send large documents to a printer that is not connected locally to the thin client. If you want to print multiple documents, allow the print queue to clear before submitting the documents.
One possible solution is to install the “winbind” package from the Debian repositories using Synaptic or Aptitude and configure for the specific environment. After installed, edit from a command line /etc/ nsswitch.conf and add the word wins to the end of the hosts: line. ISSUE Attempts to ping the client result in message “unknown host” error. SOLUTION Ensure the host name is correct and includes a fully qualified domain name (FQDN) for the applicable domain where the thin client is located.
