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.
Typically, to configure multiple terminals, you can configure a terminal locally and then use it as a
template for other terminals, which you can then configure using remote administration tools.
NOTE: A default administrator account is pre-installed with the following settings: User name and
Password = root. Additionally, the HP t5735 ships with a basic user account with the user name and
password = user. By default, the t5735 will autologin into the user account. HP recommends that you
change the user and root passwords as soon as possible. See
information on accessing the root account.
Login Window on page 26 for more
Thin client image
The HP t5735 Linux thin client offers an extensible Linux image built upon Debian GNU/Linux. HP has
extensive Debian experience and selected Debian as the foundation for its thin client based on its
stability, security, and market acceptance. Debian includes a package management system that ties
into repositories maintained by the Debian community, HP, and others. Package is the generic term for
all software, drivers, features, etc., that are “wrapped” in code that allows the software to be easier to
automatically install into proper directories and check for any other dependences that are required to
ensure they work properly once installed. Once created, packages reside in various repositories that
are maintained by the Open Source Community for open source packages. HP hosts a unique repository
for updates and features specifically for the HP t5735. Aptitude is a command-line and/or text-based
GUI program for connecting to and managing packages locally and in a repository.
This image also comes with FTP update for installing new packages and settings files using an FTP
server and ThinState capture. For more information about ThinState, see
on page 28.
You can use the Altiris client to provide remote management of the thin client and to upgrade the Linux
image with feature enhancements, device drivers, and maintenance updates.

ENWW Thin client image 1
Desktop options
This section describes the Linux thin client desktop.
By default, at least three objects appear on the desktop:
Computer icon—This icon gives you access to removable media such as USB flash drives, as well
●
as to the entire filesystem (also known as the root filesystem). By default, you do not have the
security permissions to read other users' files or to edit system files. It allows you to see a graphical
representation of the files and folders on the system and to browse the various folders.
User’s Home icon—Your Home Folder is labeled username's Home; it’s where all of your personal
●
files are kept.
Trash icon—Trash is a special folder in which to place files and folders you no longer need.
●
When you insert a flash drive or other removable media, a corresponding icon appears on the desktop
and a window opens and displays any files and folders on the device.
As you work with your HP Compaq thin client, the desktop may become obscured by the windows you
are working with. To reveal the desktop quickly, you can minimize all windows by doing one of the
following:
Click the Show Desktop button at the bottom left of the screen.
●
Press Ctrl+Alt+D.
●
Either action will also restore your windows to their previous state. Alternatively, you can switch to
another workspace to see the desktop.
The files and folders you put on the desktop are stored in a special folder within your Home Folder called
Desktop. Like any other folder, you can put files and other folders directly into it.

8 Chapter 1 Introduction ENWW
Synaptic
Thin client software is organized into packages. Synaptic provides a graphical user interface to the
package manager that allows you to easily add, upgrade, and remove packages on your thin client.
NOTE: Synaptic Package Manager is only usable from the Root desktop
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.
Synaptic provides the following features:
●
●
●
●
●
●
●
●
Install, remove, configure, upgrade, and downgrade single and multiple packages
Upgrade entire system (not recommended)
Manage package repositories
Search packages by name, description, and several other attributes
Select packages by status, section, name, or a custom filter
Sort packages by name, status, size, or version
Browse all available online documentation related to a package
Lock packages to the current version
Force the installation of a specific package version
●
HP hosts a repository for t5735 options, add-on, and package updates at
tcdebian.
NOTE: To conserve flash space, Synaptic is not normally installed. The root user’s desktop has an
icon that when run will use aptitude to install Synaptic, which may be removed when no longer
necessary. To access the root user’s desktop, a user who knows the administrative password must
check the Allow local system administrator login check box on the Security tab of the Login Window
applet in the Desktop/Administration menu.
You must log in as root or a user in the Administrator group to use Synaptic. Click Desktop > Log Out
User > Log Out to open the administrator login windows.
Reload package information regularly so you do not miss important security upgrades.
Synaptic requires an active network connection to work properly.
Synaptic requires that the thin client have Internet access.
If the HP Repository appears to be down or does not connect when trying to update the package list,
wait and retry.
From time to time HP may release new or updated packages to the HP repository. HP packages
have hptc- at the beginning of their name (i.e., hptc-control-panel); however, for the benefit of our
customers, other vendors may also post packages in the HP repository (i.e., ICA updates, ThinPrint
packages, etc.) that follow the vendor's naming convention and therefore do not begin with hptc-.
ftp://ftp.hp.com/pub/
The first time you launch Synaptic, it decompresses itself and loads the list of all available packages
from default ftp sites.
ENWW Synaptic 9
To launch Synaptic for the first time:
1. Click Desktop > Administration > Login Window, and click the Security tab.
2. Check the Allow local system administrator login check box.
3. Enter proxy information, if necessary (Applications > System Tools > HP Network Manager).
4. Log out and login again as root.
5. Select the Synaptic icon on the desktop.
An xterm window opens.
6. Type Y, and then press Enter.
The install results are displayed on-screen.
7. 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.
Alternatively, you can open a root terminal and enter the command aptitude update && aptitude
install synaptic after performing any necessary proxy configuration, as described above.
The Synaptic Package Manager window includes a pane (left) that allows you to list packages by
category, a pane (upper right) that lists all packages within a selected category, and a pane (lower right)
that provides information about a specific selected package.
For detailed information about a package, including size, version number, dependencies, files, and
more, right-click the package and select the Properties button.
To install packages on the thin client:
NOTE: Be sure to read the installation messages, as they can require user input. Installing or removing
packages requires administrator root permissions.
1. Open Synaptic Package Manager by double-clicking Synaptic on the desktop.
2. Click Search to open the Find dialog box.
3. Type a parameter of what you are searching for in the Search field, then select the search category
in the Look in list, and then click Search. The upper right pane displays all packages located based
on your search criteria.
4. In the upper right pane, select the specific package to install. If desired, read about the selected
package in the lower right pane.
5. In the dialog box, select the installation option based on the type of installation you are performing.
6. If necessary, repeat steps 2 - 5 to location and mark more packages for installation.
7. Click Apply.
8. Confirm the action and click Apply.
9. Click Close after all packages are successfully installed.
10 Chapter 1 Introduction ENWW
NOTE: When uninstalling packages, Mark for Removal uninstalls the package from the thin client
without removing the configuration files. Mark for Complete Removal removes all traces of the package
from the thin client.
For more information about Synaptic functions and features, go to the local Synaptic help file (launch
the Iceweasel Web browser and go to
TeemTalk
file:///usr/share/synaptic/html/index.html).
TeemTalk is the essential connectivity tool for enabling non-X based applications to be run in the X
environment. TeemTalk provides precise emulation of a wide range of industry standard terminals with
impressive additional features formulated to increase productivity and reduce network loading. These
include dynamic window sizing, hotspots, soft buttons, keyboard mapping, mouse button definition and
customizing capabilities. TeemTalk integrates seamlessly into the X Window system with the same look
and feel as other applications.
NOTE: The X Window System is a network-based windowing system that provides a common
graphical interface for application programs. It defines how applications create windows and the
graphics displayed in them.
The basic function of TeemTalk is to accept command sequences from a host application (client) and
convert them into equivalent X functions, which can then be passed on to the X display server. This
means that current investment in host application software can be retained in the X Windows
environment.
Each window displayed by TeemTalk is, in effect, a separate 'terminal'. Several terminal emulation
windows may be displayed simultaneously on the same display server, all running different programs.
ENWW TeemTalk 11
