ThinLinc 4.12.0 Release Notes


Cendio are proud to present ThinLinc 4.12.0, with more than 40 enhancements and fixes. The most prominent changes are:

  • Clipboard now supports all Unicode characters. That means you can now copy and paste things like the Greek alphabet, the Cyrillic alphabet, mathematical symbols, or even emoji between your local desktop and your ThinLinc session.
  • The native client and Web Access now both support various touch gestures that makes ThinLinc easier to use on devices without a standard mouse. E.g. tapping two fingers for a right click, or dragging two fingers to simulate a scroll wheel.
  • ThinLinc now requires systemd for its services and no longer supports the classical SysV init system.

ThinLinc works on most modern Linux distributions and is supported on any platform that fulfills our documented requirements.

Changes in This Release

In the list below, the bug number is given in parentheses. For more information, visit


  • To improve compatibility with newer systems, ThinLinc server now uses systemd instead of SysV for services. This also means that ThinLinc server cannot run on systems without systemd. (4290)


  • Copying and pasting text in and out from the Thinlinc session now supports all Unicode characters. Previously only ISO 8859-1, also called "latin 1", was supported. Note that both the server and client must be up to date for this to work. (3895)

Native Client

  • The ThinLinc Client now supports touch gestures for common actions such as right-clicking, scrolling, and zooming. (7111)
  • The ThinLinc Client for Windows is now signed with a new certificate. Windows Defender SmartScreen may show a warning until this new certificate has built enough trust with Microsoft's servers. (7407)
  • Remove the built in control panel. Users should use the normal system configuration interfaces on their client devices to configure keyboard, mouse and screen settings. (5325)
  • Added the possibility to emulate middle mouse button by pressing left and right mouse buttons simultaneously. (3990)
  • Fixed an issue where system keys were not sent to the session when running the client on Linux with Wayland. (5647)
  • Fixed an issue where the ThinLinc client might stop updating the display when maximized. (7265)
  • Fixed an issue where authentication prompts or server banner messages could be cropped at around 1000 characters. (7513)

ThinLinc Web Access

  • Web Access now supports touch gestures for common actions such as right-clicking, scrolling, and zooming. (5348, 7111)
  • Alpha cursors are now supported in Web Access. Previously, a cursor pixel could only be fully opaque or fully transparent. Now all transparent parts of the mouse cursor are handled fully, just like in the native client. (7374)

Smart Card Support

  • Fixed an issue where applications could crash when used with SafeNet smart card middleware. (7499)

Printing Support

  • Modern versions of CUPS are now supported for thinlocal and nearest. (7509)

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.
