Introduction

Getting started

Use the following information to learn the basics and get started using your thin client:

● Logging in to your thin client device

● Using your ThinLinux desktop

● Configuring thin client settings and connections

● Viewing system information

● BIOS settings

Logging into your thin client device

On your initial configuration, Dell recommends that you connect by using a wired connection by plugging in the network connected Ethernet cable to your thin client.

The Quick Start application launches when you boot into a thin client for the first time. This application displays the software and hardware features of the thin client. It also provides information about the VDI applications, management software, and supported peripherals.

NOTE: You can also start the Quick Start application later from the ThinLinux desktop.

After you exit the Quick Start application, you are automatically logged in to the thinuser account. The default password of the thinuser account is thinuser.

NOTE:

If a GDM login is needed—AD/Domain login, PNAgent login, and so on—the autologin option can be turned off

through the GUI or by using INI.

Admin mode enables you to perform system administration tasks such as adding or removing connections and setting up specific device settings. To switch to admin mode, click the Switch to Admin button on the Settings application screen and enter the default root password in the Authentication required window. The default root password is admin. You can also press Ctrl + Shift + Alt + F11 to switch to admin mode.

Application overview screen

ThinLinux boots to the application overview screen. This is the default ThinLinux screen that is displayed after you log in to the thin client (without auto-start of any connections or application).

Figure 17. Other settings

To configure the other settings, do the following:

1. In the Source section, configure one of the following options:

● Contact DHCP server—If you set the hostname of the thin client by selecting the DHCP server option, the hostname is

set to the standard host-name tag received from the DHCP server. If the DHCP server does not provide the host- name tag, the device retains the previously set hostname.

● DNS reverse lookup—If you select DNS reverse lookup option to enter the hostname of the thin client, a reverse

DNS lookup operation is performed using the existing IPv4 address of the thin client, and the hostname is set to the received value.

NOTE:

The previous hostname is retained if the device cannot perform a successful reverse DNS lookup operation due to reasons such as, network connection is not established, DNS servers are not established or are invalid, and the IP address is not in the DNS server’s list.

● Derive from MAC address—Select the Derive from MAC address option to specify the host name of the thin client. You can specify the hostname by using the MAC address. The Ethernet of the thin client interfaces with the MAC address. It creates the hostname by extracting the MAC address from its field separators, such as, (:) and the MAC address is prefixed with the string LWT. For example, a device with MAC address of 00:80:64:c1:8b:14 has MAC derived hostname as LWT008064c18b14. If you want to use the manually named device as a seed device for Merlin image pulling, you must be cautious in specifying the hostname manually. The changed hostname is pushed to other devices and these devices use the same hostname. Only through device factory reset, you can recover the default value by using MAC address.

● Use the following name—This option enables you to enter your preferred hostname. When you log in to the session, the screen displays the previous hostname in the box and in the Terminal option.

The hostname entered is not authenticated if the string entered has a white space. The first part of the

NOTE:

string up to the first white space is used to set the hostname of the devices. All white spaces at the beginning of the string are ignored, and the maximum hostname string size is 64.

2. In the Additional entries to /etc/hosts section, you can set the device name and update the entries on the /etc/hosts file. This option enables you to add to the preset default data, and update or delete the existing entries. To configure this option, do the following:

a. Enter the IP address, host name,and Aliases in the respective fields.

not displayed on the desktop.

If the Settings app is hidden, and if you log into the thin client with user credentials, then you cannot open the Settings app or switch to the admin mode. You can restore the Settings app using one of the following methods:

○ Use INI parameters. ○ Log in to the thin client with admin credentials and enable the Settings option. ○ Perform a factory reset or factory recovery.

● Quick Start—Click the ON/OFF button to enable or disable this option. If you enable this option, the Quick Start

application is not displayed on the desktop.
