Citrix Receiver for Linux 12.0 features exciting HDX enhancements that deliver a high definition user experience, best-in-class server scalability and superior bandwidth efficiency. Version 12.0 of the Linux Receiver aligns with XenDesktop 5.5 and XenApp 6.5, announced in August. This release has been in incubation for a long time (special thanks to everyone who provided feedback on the May Tech Preview release!) and we are very excited to let our customers and partners get their hands on it.
Here are some of the key features in this release:
HDX MediaStream Flash Redirection: Citrix’s unique Flash Redirection technology allows end users to play back high definition videos and other Adobe Flash content while reducing the bandwidth requirements and improving server scalability. We do this by leveraging the smarts in the end user device and play the Flash content locally rather than on the server. This allows us to provide significant performance improvement over competing technologies.
This release introduces our Flash Redirection technology on 32-bit Ubuntu and Fedora and x86 based platforms, and we are actively pursuing avenues to support other popular Linux distributions and platforms in the near future.
Advanced HDX 3D Pro support: The Linux Receiver 12.0 introduces advanced support for XenDesktop 5.5 HDX 3D Pro, our industry-leading solution for delivering high-end 3D professional graphics (see Derek Thorslund’s recent blog post).
- Support for HDX 3D Pro specialized codecs: HDX 3D Pro offers deep compression for limited bandwidth WAN connections via a GPU-based codec, and Linux Receiver 12.0 is able to decode this deeply compressed data either on the CPU of the user device (minimum 2 GHz processor) or, if available, on the GPU. The end user benefit is a rich experience for users of professional graphics with low bandwidth consumption.
- Multi-Monitor Support: HDX 3D Pro isn’t just for remote access; with multi-monitor support it’s also a great solution for graphics workstation replacement, enabling IT to centralize 3D graphics processing in the data center. With this feature, users now have the freedom to not only use multiple monitors but also arrange them in any configuration and mix-n-match them with different resolutions and orientations.
The HDX 3D Pro features are offered on x86-based platforms.
HDX RealTime Webcam Video Compression: Prior to the introduction of this technology, we provided generic USB redirection as a mechanism to support webcams for Unified Communication applications. While the technology worked great in LAN environments, it didn’t scale very well in WAN environments and under challenging network conditions. With the introduction of Webcam Video Compression, we now compress the webcam video before sending it to the server. This results in dramatic improvements in the data traffic and provides a much better user experience in both LAN and WAN environments.
Our testing for this feature focused on popular Unified Communications clients such as Skype, Microsoft Lync and our own GoToMeeting HDFaces. We believe that our generic solution will be extensible across a wide array of Unified Communications clients and expect to add to the list over time.
VoIP Support: For VoIP applications, we have made significant reductions in audio latency and improved resiliency for long duration calls.
Support for audio from multiple sources: With the introduction of the ALSA sound subsystem, we now support audio from multiple sources. With this improvement, a user can, for example, hear the ring tone from an incoming call while watching a webcast using the USB headset.
Password Expiration Support: Prior to the introduction of this feature, upon expiry of their Active Directory password users would have to login to their virtual desktop and change their password using the Windows interface. With this change, users are prompted to change their password upon expiry on the Linux client itself.
Win7 VDA Smartcard Support: With this functionality, we now allow smart card authentication on virtual desktops running Windows 7.
