ThinLinc 3.1.0 Release Notes

Introduction

A new ThinLinc release is finally here, the first of this decade. It includes more than 150 enhancements. The most prominent features are:

  • Support for new platforms, such as Windows 7 and 64-bit versions of Windows Server
  • Many smart card improvements
  • Major enhancements for Virtual Desktop Infrastructure deployments:
    • Integration with VMware Virtual Infrastructure environments
    • Support for personal and shared pool machines
    • Web-based administration GUI

ThinLinc 3.1.0 has also been tested with VirtualBox 3.1. When used in conjunction with VirtualGL, the system can deliver high performance graphics with OpenGL applications running on Windows.

Changes in This Release

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

Server

  • ThinLinc works on most modern Linux distributions and Sun Solaris (R). This release has been extensively tested on the following platforms:
    • Red Hat (R) Enterprise Linux 5.4 (64-bit)
    • SUSE Linux Enterprise Desktop 11 (R) (32-bit)
    • Ubuntu (R) 9.10 (32-bit)
    • Sun Solaris (R) 10
Note: The 64-bit version of SUSE Linux Enterprise Desktop is currently not recommended, since it does not provide a full 32-bit environment.
  • The performance of the X server has been increased. For example, the "gtkperf" performance test typically indicates a performance increase of 50%. (3449)
  • ThinLinc can now be installed in a non-global Solaris Zone. (3286)
  • The "homecreatefilter" now works with modern versions of Firefox. (3340)
  • The "lsof" command is no longer required on agent servers. "netstat" is required instead. (2975)
  • The default session DPI has been changed from 100 to 96, which is more common. (3351)
  • When reconnecting using a different session size, the DPI value was incorrectly changed. (3144)
  • A stability problem related to malformed vsmserver requests has been corrected. (3106)
  • A keyboard problem which could cause modifiers such as "shift" to stick has been corrected. (3143)
  • A keyboard problem affecting dead keys and the Windows client has been fixed. (3156)
  • On rare occasions, some portions of the screen were not updated. This has been corrected. (3108)

General

  • The base system requirements for both the server and client have been raised. For Linux, glibc 2.3.4 or newer is required. (2910)
  • This release has not been translated to Brazilian Portugese. (3437)

Client

  • Windows 7 and Windows 2008 R2 have been added to the list of supported client platforms. (3063)
  • The visual appearance of the client has been updated, including support for font anti-aliasing. (2405,3027)
  • The Solaris client now requires Solaris 10. (3422)
  • If the previous version of the client was configured to automatically select "encoding" (this is the default), it did not always select the fastest one. This could result in poor graphics performance. This problem has been fixed. (3416)
  • The RPM package now includes correct library dependencies, which makes it easier to install on 64-bit systems. (3024)
  • A problem related to copy/paste from a ThinLinc session to a local Linux system has been fixed. (3120)
  • Client packages for terminals from Neoware, VXL, and HP are no longer provided. If you need to run the 3.1.0 client on such terminals, we recommend a migration to the eLux platform. See http://myelux.com/ for more information. (3133)
  • The previous version of the client did not support smart cards on recent versions of eLux (version 2.6.0 and newer). (3480)
  • The 3.0.0 Windows client was not focused after connect. This has been corrected. (3136)
  • A compatibility problem with ThinLinc 2.1.0 servers running on Solaris has been fixed. (3363)
  • Exporting a "My Documents" directory containing international characters did not work; this has been corrected. (3212)
  • When the client starts, it will now move any existing log file to tlclient.old.log, preserving its content. This makes it easier to diagnose problems on terminals where the client is configured to automatically restart. (3305)

Smart Card Support

  • When the client is configured to automatically connect when a smart card is inserted, the certificate to use can be selected based on the certificate issuer. (3272)
  • The client now supports unlocking PIN codes, provided that the user enters a valid PUK code. (2598)
  • The previous client did not show all certificates on certain smart cards. This has been corrected. (3275)
  • Smart card certificates with very long "subject names" are now correctly handled. (3294)
  • The Windows client can now handle smart cards with multiple private keys. (3405)
  • Smart card redirection now works on Linux systems with SELinux activated. (3414)
  • Many smart card error conditions are handled better. (3296)

Virtual Desktop Infrastructure (VDI)

  • Pools of common machines are now supported, in addition to dedicated personal machines. (3036, 3072)
  • Smart dynamic allocation/deallocation of common machines for authenticated users, including power operations, is now supported. (3232)
  • Support for VMware vSphere (R) has been added. (3173)
  • Support for linked clones has been added (requires vSphere/ESX 4.0). (3174)
  • Support for cloning machines from snapshots has been added (requires vSphere/ESX 4.0). (3396)
  • A new web-based VDI administration module has been added. (3229)

Desktop Customizer

  • Desktop entries (.desktop files) handled by the Desktop Customizer are now marked as executable files, for compatibility with modern Linux desktop environments. (3165)
  • Common menus and application groups are included by default. (3200)

Novell Integration

  • When previous versions of tl-nds-posixuser failed to find a free uid, a uid of -1 was incorrectly used. (3344)

Windows (R) Integration

  • Please note that Windows Server 2008 is a supported server platform, but Windows Server 2008 R2 is not. (3301)
  • The software package for Windows Terminal Servers ("WTS Tools") now supports 64-bit systems. This means that features such as SeamlessRDP now works correctly on Windows x64 editions. It is also possible to mix 32- and 64-bit applications on such systems. (2764, 2986, 3428)
  • The RDP client (rdesktop) automatically resizes the Windows desktop when the size of the ThinLinc session changes. This makes it easier to reconnect to Windows desktop sessions from a terminal with a different screen resolution. (3043)
  • The RDP microphone driver (tlsnd) works on Windows XP now, even when reconnecting to existing sessions. (3219)

TLCOS

  • TLCOS is configured for smart card usage. (3178)
