VMware Horizon
  • Remote applications are not seamless in the strict sense. These are rather displayed in an extra window decorated by the TC's window manager.
  • If more applications defined and started in the same session, all are displayed inside this window. The default size of this window can be defined in the Window section of the Horizon session.
  • On UD3 50/IZ3 50, accelerated H.264 decoding is only possible for Blast sessions with screen heights up to 1152 pixels due to hardware limitations. If sessions exceed 1152 pixel height, the GL-Basic rendering engine is used instead. Current Horizon Blast implementation also shows a certain lag on this type of hardware which increases over time, so that usability decreases accordingly.
  • Client drive mapping and USB redirection for storage devices should not be enabled both at the same time.
    • On the one hand, if you want to use USB redirection for your storage devices: Note that the USB on-insertion feature is only working if the client drive mapping is switched off. In the IGEL Setup client drive mapping can be found in: Sessions > Horizon Client > Horizon Client Global > Drive Mapping > Enable Drive Mapping. It is also recommended to disable local Storage Hotplug: On page Devices > Storage Devices > Storage Hotplug, put number of storage hotplug devices to 0.
    • On the other hand, if you use drive mapping instead, it is recommended that you should either switch off USB redirection entirely or at least deny storage devices by adding a filter to the USB class rules. And because Horizon Client relies on the OS to mount the storage devices itself, please go to setup page: Devices > Storage Devices > Storage Hotplug and switch on "Enable dynamic drive mapping" and put "Number of storage hotplug devices" to at least 1.


Quest vWorkspace
  • Seamless applications exported from Win8/8.1 desktops show display errors when dragged to the screen edges.
  • At dual view configuration flash redirected windows can appear on wrong screen.
  • After the start of a seamless session the window is initially maximized before being resized to the correct size.
  • Windows XP sessions might not work properly anymore.
  • Only standard 105 keys PC keyboards are supported. Not supported anymore: Trimodal, Sun Type 6 or IBM 122 keys.
  • Mapping of drives to a dedicated drive letter is not possible anymore.
  • If Com-port redirection is enabled all linux serial ports (/dev/ttySx) will be mapped.
  • If printer mapping is enabled, all printers configured in CUPS are mapped.
  • For Multimedia Redirection, sound redirection with WMV/WMA streams is not working.
  • USB Redirection may not work reliably.
  • Session starts only if RDP Local Logon Window (IGEL Setup > Sessions > RDP > RDP Global > Local Logon) is active.

X11 system
  • The IGEL devices UD2 30/31 (D210), IZ2 30/31 (D210) and UD3 30/31 (M310) automatically use the VIA fallback driver since the new driver does not support these devices reliably enough at the moment. To disable the automatic fallback feature, disable registry key.

    Parameter

    Use VIA fallback driver for VX855 chipset as default

    Registry

    x.drivers.via.fallback_vx855_auto_use

    Value

    enabled / desabled


Universal MultiDisplay
  • While updating the UMD slave devices from 5.10.100 or older firmwares there will be screen flickering and corruptions until the end of the update.
