This topic describes the system and user requirements for installing Receiver for Linux.
The device requirements listed in this topic apply to 32-bit and 64-bit systems. Receiver for Linux is a 32-bit program, and requires 32-bit libraries in the system to operate. You can use the 64-bit package to install the 32-bit version of Receiver on 64-bit systems, but suitable 32-bit system libraries must be available. If they are not, Receiver either does not install or does not function correctly.
For x86 devices, processor speeds of at least 1.6 GHz display single-monitor sessions well at typical resolutions (for example, 1280 x 1024). If you use the HDX 3D Pro feature, a native hardware accelerated graphics driver and a minimum processor speed of 2GHz are required.
For ARM devices, a hardware H.264 decoder is required for both general H.264 support and HDX 3D Pro. Performance also benefits from faster processor clock speeds.
HDX MediaStream Flash Redirection
For all HDX MediaStream Flash Redirection requirements, see CTX134786.
The version of the Adobe Flash plug-in running on the user device must be either the same as or later than the version running on the XenApp or XenDesktop server to support client-side rendering. If this is not the case, only server-side rendering is available.
Citrix recommends always upgrading to the latest version of the plug-in to obtain the latest functionality and security-related fixes.

If you plan to use Philips SpeechMike devices with Receiver, you may need to install the relevant drivers on the user device. Go to the Philips web site for information and software downloads.
Availability of Receiver for Linux 13.0 features
Some of the features and functionality of Receiver are available only when connecting to newer versions of XenApp and XenDesktop and may also require the latest hotfixes for those products.
Although you do not need to log on as a privileged (root) user to install the Citrix Receiver for Linux, USB support is enabled only if you are logged on as a privileged user when installing and configuring Receiver. Installations performed by non-privileged users will, however, enable users to access published resources using either StoreFront through one of the supported browsers or using Receiver's native user interface.
Citrix provides a script, hdxcheck.sh, as part of the Receiver installation package that checks whether your device meets all of the system requirements that let it benefit from all of the functionality in Receiver for Linux. The script is located in the Utilities directory of the installation package.
