The Linux remote desktop server built on open source technology.

ThinLinc 4.0.0 Release Notes


A new ThinLinc release is finally here, version 4.0.0. It includes over 100 enhancements. The most prominent features are:

  • Support for systems with multiple monitors has been greatly enhanced. Primarily this means that the ThinLinc client can now be used on devices with multiple monitors, and the ThinLinc session will respect monitor boundaries just like a local desktop would.
  • A 64-bit client is now available for Linux. This makes it easier to install on most modern distributions, and will also give a performance boost.

Changes in This Release

In the list below, the enhancement number is given in parentheses.


  • ThinLinc works on most modern Linux distributions and Oracle Solaris (R). We recommend that you deploy ThinLinc on one of these tested platforms:
    • Red Hat (R) Enterprise Linux Server 6 (64-bit)
    • SUSE Linux Enterprise Desktop 11 SP2 (R) (64-bit)
    • Ubuntu Desktop (R) 12.04 (64-bit)
    • Sun Solaris (R) 10
  • The installation program has been updated with several bug fixes to increase compatibility. (4360, 4442, 4446)
  • The startup scripts will now fetch a Kerberos ticket for the session by default. (4301)
  • The notifications for session shadowing has been made more robust against false warnings. (4321)


  • The client and the server now both fully support multiple monitors. This includes both making sure the session covers all monitors, as well as exporting monitor dimensions to the server for correct window placement inside the ThinLinc session. (14, 2426, 3094, 4229)


  • A 64-bit version of the Linux client is now available. (3230)
  • Compatibility with Mac OS X 10.8 has been improved. (4366, 4368)
  • Client window placement has been improved in multi monitor environments. It should now avoid crossing monitor edges, and the session will always be displayed on the same monitor as the login window. (3892, 4275)
  • Sessions are now dynamically resized as the local client window is resized. Previously a reconnect was required to resize the session. (3673)
  • A performance issue on AMD Bobcat CPUs has been identified and fixed. These CPUs are found in several recent terminals. (4328)
  • The installation programs for the Windows client are now signed, increasing security on that platform. (2075)
  • The Java client applet is now signed with a trusted certificate. This avoids unnecessary security warnings. (4402)
  • A security issue in the Java client has been resolved. The PAM account checks were not properly performed, allowing users with locked accounts to log in. (4460)
  • Support for Thinstation has been updated from version 2 to version 5. (4318, 4349)
  • Windows 2000 is no longer a supported platform for the client. Users are encouraged to upgrade to a later version of Windows. (4367)
  • The client now better supports systems that have case sensitive user names. Previously, the client always converted the user name to lowercase. This is now optional, and the default is not to alter the name. Please note: this means that in some configurations, the user name field in the earlier client was perceived as case insensitive, while the new version will require correct case. (2197)
  • Edge scrolling, also known as bump scrolling, has been restored when the client is in full screen mode. This feature was lost in ThinLinc 3.2.0. (4343)

Smart Card Support

  • The bundled OpenSC library has been upgraded, increasing compatibility with modern cards. (4377)
  • The Linux client will no longer ask for a PIN even if the server rejects the certificate. (2991)

Audio Redirection

  • The embedded PulseAudio server, which is used for audio redirection, has received a major upgrade. This will increase compatibility with modern desktop environments and applications. (2505, 3222, 3227, 4346)

Windows (R) Integration

  • The RDP client now supports Transport Layer Security (TLS) 1.0. TLS is the latest version of the Secure Sockets Layer (SSL) protocol. (4347)
  • SeamlessRDP should now be better at ignoring command line windows (which cannot be properly exported seamlessly). (2369)
  • SeamlessRDP is now better at determining when a session should be terminated. (4007)
