Webcams not enumerated in Xendesktop Session

I have come across an issue recently whereby certain webcams are not enumerated correctly in a Xendesktop session. The issue appears to be with certain webcams and there lack of support for switching to the default resolution of 352 x 288. By modifying a certain key within the registry you can fixed the setting to a more common resolution ie 320 x 240. The registry key in question is the HKEY_CURRENT_USERSoftwareCitrixHDXRealTime you will need to create the following values:- Name: DefaultWidth Type: REG_DWORD Data: 320 (decimal) Name:DefaultHeight Type: REG_DWORD Data: 240 (decimal) Once this is added you should see that the webcam gets redirected within the session without any problems.

vSphere 5.1 GPU acceleration now supported on XenDesktop with HDX 3D Pro and XenApp with HDX 3D

VMware recently introduced GPU hardware acceleration support for its latest hypervisor release, vSphere 5.1. XenDesktop 5.6 FP1 and XenApp 6.5 FP1 have tested successfully with the new GPU acceleration capabilities on vSphere 5.1 and Citrix officially supports these configurations. vSphere 5.1 introduced two GPU acceleration methods: Direct graphics acceleration (vDGA) and Shared graphics acceleration (vSGA). vDGA is similar to XenServer’s GPU pass-through method where each graphics processor supports a single VM to enable high performance rendering for designers and engineers that require a dedicated GPU or for GPU sharing with multi-user XenApp VMs. vSGA is a light-weight implementation of GPU sharing designed for business graphics such as Microsoft Office and Windows Aero graphics and may not be suitable for demanding 3D professional graphics applications such as CAD, geographical information systems and medical imaging. vSGA is based on API Intercept,…
