ThinLinc 1.4.1 Release Notes


The ThinLinc team is proud to present ThinLinc version 1.4.1. This version includes many corrections as well as several new features. In total, this release contains more than 160 enhancements.

Changes in this release


  • ThinLinc works on most modern Linux distributions. This release has been extensively tested on the following platforms:

    • Red Hat (R) Enterprise Linux 4

    • SUSE (R) LINUX Enterprise Server 9

    • Debian (R) 3.1

    • Sun Solaris (R) 8

  • The server can be configured not to allow connections from Windows clients without updated antivirus software. (1415)

  • The nearest printer queue now supports non-PostScript (R) printers. (1272)

  • The nearest and thinlocal printer queues handles error conditions much better. (1354)

  • A new utility called tl-session-param can display session parameters. (1442)

  • The client IP address is available as a variable in the session. (1359)

  • The OpenGL support has been enhanced, and now supports a wider range of applications. (1297)

  • A problem with horizontal graphic distortions has been fixed. (1444)

  • The fontpath is now configurable. A fontserver is no longer required. This means that ThinLinc can now run on distributions that doesn't include a fontserver, such as Ubuntu. (1150)

  • ThinLinc now works correctly on Python 2.4 platforms suffering from Python bug 1177468. This means that ThinLinc now works on distributions such as Fedora Core 4 and Suse Linux 9.3. (1305)

  • The ThinLinc Desktop Customizer now supports defining names and descriptions for applications in multiple languages. (974)

  • The ThinLinc Desktop Customizer now supports defining hidden menus, which makes it easier to use file associations in KDE. (1224)

  • The tools tl-umount-all-cifs, tl-umount-all-ncp, and tl-umount-localdrives can now (optionally) unmount all mounts with the type in question, when executed by an administrator. (526)

  • The installation program supports Debian-based distributions better. It is now possible to answer interactive questions from DPKG. (1216)


  • The Windows client can verify the local antivirus software. It can be configured not to allow login if no updated antivirus software is running. The client also reports information about the antivirus software to the server. (1415)

  • The default VNC encoding is now ZRLE. This encoding is faster in most cases and consumes less CPU on the client. (1215)

  • The Windows client now correctly works on systems where the TEMP environment variable contains spaces. (1334)

  • A problem affecting copy-paste of international characters with the Windows client has been corrected. (1389)

  • The fully statically linked client has been removed. (1461)

  • This version of the ThinLinc client is supported on TLCOS versions 1.3.2 and 1.4.0, in addition to TLCOS 1.4.1. (1485)

  • When encryption is turned off, the client can now correctly detect when a firewall is blocking the server connection. (359)

  • Local Drive Redirection now works correctly with applications such as OpenOffice.Org, even when the server is running Linux 2.6. (931)


  • The user interface of the network setup dialog has been greatly enhanced. It is now possible to print a test page as well. (1293)

  • The LiveCD now supports WiFi networks. Wired Equivalent Privacy (WEP) is also supported. (1327)

  • It is now possible to use a Webb Browser when connecting to the network. This is useful in case a network authentication is required. (1378)

  • Shutdown is much faster. (996)


  • A default sound volume is now set. (1207)

  • TLCOS now asks for a root password during the installation. (1496)

Novell Integration

  • A new tool, the ThinLinc Novell Configurator, has been added. This tool makes integration of ThinLinc into an eDirectory environment very easy, allowing most configuration to be performed with a single click. (1106)

Windows (R) Integration

  • The support for applications requiring Num Lock syncronization has been enhanced. (400)


  • If the CIFS server accepts the username and password entered in the ThinLinc client, it is no longer necessary to authenticate a second time before using the safelinc share. (1074)

  • It is possible to configure the client to display the SafeLinc shares directly after login. (848)

  • The client now warns if the SafeLinc ports are in use. This is the case on certain versions of Windows XP. (1294)


  • The documentation now includes information on how to authenticate against Windows servers using Samba 3. The instructions for Samba 2.2 has been removed. (1310)

  • Documentation for the LiveCD is now included. (1212)

  • Information about the different types of thin terminals that the ThinLinc client runs on has been moved from the client CD to the User Guide. (1199)

  • The FAQ includes information on how to create a clean KDE desktop. (1332)


If you have installed any 1.4.0 "hotfix" packages, these must be removed prior to running the installation program. On RPM based systems, this can be done with the command:

rpm -e --nodeps rpm -qa | grep thinlinc.*1.4.1pre.*

Historically, good compatibility between versions has been 3-5 years.

  • A ThinLinc set-up consists of a server software, client software and user licenses.

    Server software

    The server software is the heart of ThinLinc installation and handles all sessions, desktop environments and generates the virtual desktop, workspace etc.

    User licenses

    To allow more than 10 sessions to connect access to the server software, user licenses need to be added into the server software. User licenses are bought from Cendio. Please note, when placing user licenses into the ThinLinc server, the counting starts from 0, not 10. In concrete, this means that you need to buy and install the number of user licenses that you need.

    Client software

    The client software is installed on the device that is used to connect to the server and provision the virtual desktop / workspace. If using the web access client, no local installation of client software is needed, the provisioning is generated via the web browser that is installed at the server.

  • It’s up to the licensee to decide who can connect into the server installation. The ThinLinc client software is free of charge and can be downloaded by everyone.

  • The licensing is per organization. There is no limitation on how the ThinLinc user licenses are distributed in the legal organization, as long as the number of consumed licenses don’t exceed the number of paid licenses. It’s allowed to move the user licenses, but not copy.

  • The license use can be seen in the status module, how to manage can be found at . ThinLinc will notify you when the limit of licenses has been reached, for detailed information see,

  • Both the ThinLinc server and client software are free to distribute. The user licenses are connected to a purchase and are not allowed to distribute. For more detailed information, see

  • A specific version of ThinLinc is supported 3 years from release date. After 3 years, Cendio can’t guarantee support.

  • The number of user licenses that will be delivered will be in accordance with the number of subscriptions that have been acquired by the customer. The user licenses are perpetual.

  • When adding user licenses into the ThinLinc server, the counting will start from zero. So if you require 200 users, you need to have 200 user licenses

  • You need to buy user licenses and install them in the ThinLinc server. The user licenses are received through buying ThinLinc subscriptions.

  • It’s easy to add new users into a current ThinLinc set-up. By purchasing additional subscriptions into your agreement, so will we issue additional user licenses.

  • Cendio will, after receiving a valid order, distribute user licenses via email for the latest version after a purchase. If the purchase is a renewal and the customers have already received the latest version, no user licenses will be delivered by default, updated licenses will be delivered on request in this case.

  • It’s possible to merge existing agreements. When doing a merge, the period shall be at least 12 months.

  • The default rule is that the prices are set in accordance with the number of subscriptions that are purchased at the actual call off. Deviation from this can be eventually agreed if a roll-out plan can be committed in advance.
