ThinLinc 4.10.1 Release Notes


Cendio are proud to present ThinLinc 4.10.1, with more than 30 enhancements and fixes. This is a minor update with important fixes for the previous version of ThinLinc. The main focus of this release is improving compatibility with modern distributions such as Red Hat Enterprise Linux 8 and SUSE Linux Enterprise 15 and making it easier to install ThinLinc on those distributions.

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


  • An issue has been fixed where a user or program on the ThinLinc server could prevent other users from accessing their sessions. (7322)
  • Fixed an issue where assigning the root user to a subcluster didn't work. (7349)
  • The server installer now supports the DNF package manager, making it easier to install ThinLinc on modern Red Hat based systems. (5202)
  • The server installer now correctly identifies modern SUSE Linux Enterprise systems, allowing it to automate the installation of packages. (7337)
  • The server installer has gotten improvements in installing and finding the correct Python interpreter. (7294, 7295)
  • The server installer will now fall back to using text mode when it detects it cannot use the local display as root (e.g. when using Wayland). (6192)
  • The server installer now allows more variation in what the SSH service is called in the system firewall settings. This allows the installer to configure the firewall correctly on systems such as SUSE Linux Enterprise where the name of the service has changed between releases. (7338)
  • The server will now attempt to start a session even if the home directory is initially inaccessible for a user. In some cases this allows ThinLinc to work in environments that are currently not fully supported, such as systems using NFS with Kerberos. (7353)
  • The profile for the LXDE desktop environment is now properly shown on SUSE Linux Enterprise systems. (7341)

Native Client

  • The client will now display clear error messages if the selected public key file doesn't exist or isn't readable. (7207, 5317)

Local Drive Redirection

  • An issue has been fixed where files being added or removed locally to a folder that was redirected were not seen inside the ThinLinc session. This issue was only seen when using the ThinLinc client for Windows. (5560)
  • Several issues have been fixed where the timestamps on redirected files would be shown incorrectly in the ThinLinc session. (6972, 7352)

Configuration Changes


  • The default value of /vsmagent/xserver_args no longer includes "-nolisten tcp" as that is already the default behaviour of the ThinLinc X server since ThinLinc 4.10.0. It is now necessary to explicitly specify "-listen tcp" to enable X11 over TCP.

A complete configuration reference can be found in the ThinLinc Administrators Guide.

A newer version on the client-side will always give a better user experience than a former version. Cendio’s ambition is to keep good compatibility and functionality between the different versions. 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.

  • The client software packages are free of charge.

  • The ThinLinc license is perpetual and will still work after the expiry date of the ThinLinc subscriptions.
