Citrix

  • With activated DRI3 and an AMD GPU, Citrix H.264 acceleration plugin could freeze. Selective H.264 mode (API v2) is not affected from this issue.
  • Citrix has known issues with gstreamer1.0 which describe problems with multimedia redirection of H264, MPEG1 and MPEG2. GStreamer 1.0 is used if browser content redirection is active.
  • Browser content redirection does not work with activated DRI3 and hardware accelerated H.264 deep compression codec.
  • Citrix StoreFront login with Gemalto smartcard middleware does not detect smartcard correctly if the card is inserted after start of Login. 
    As a workaround, insert the smartcard before starting StoreFront login.
  • When using Citrix Workspace App 18.10 in combination with Philips Speech driver, the session occasionally terminates improperly at logout and hangs. 
    As a workaround, the usage of Citrix Receiver 13.10 is recommended when Philips Speech driver is needed.
  • Citrix H.264 acceleration plugin does not work with enabled server policy "Optimize for 3D graphics workload" in combination with server policy "Use video codec compression" > "For the entire screen".
  • When Expand the session over a self-selected number of monitors (for Multimonitor full-screen mode) is used and Setup is restarted, Restrict full-screen session to one monitor is indicated and the monitor selection is greyed out. The functionality is available, only the notification in setup is broken.
  • To launch multiple desktop sessions with Citrix HDX RTME and Citrix H.264 acceleration plugin, the following registry key must be enabled:

    This workaround is not applicable when "Enable Secure ICA" is active for the specific delivery group.

VMware Horizon

  • External drives mounted already before connection do not appear in the remote desktop
    Workaround: map the directory /media as a drive. Then the external devices will show up inside the media drive.
  • 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 under Sessions > Horizon Client > Horizon Client Global > Drive Mapping > Enable drive mapping.
      It is also recommended to disable local Storage Hotplug under Setup > Devices > Storage Devices > Storage Hotplug.
    • On the other hand, if you use drive mapping instead, it is recommended to either switch off USB redirection entirely or at least to deny storage devices by adding a filter to the USB class rules.
      Furthermore, Horizon Client relies on the OS to mount the storage device itself. Enable local Storage Hotplug under Setup >Devices > Storage Devices > Storage Hotplug.

Parallels Client

  • Native USB redirection does not work with Parallels Client.
  • For using the new FIPS 140-2 compliance mode it is necessary to connect to the Parallels RAS one time with FIPS support disabled.

Smartcard

  • In some cases, there are instabilities when using A.E.T. SafeSign smartcards.

Appliance Mode

  • Appliance mode RHEV/Spice: spice-xpi Firefox plugin is no longer supported. The Console Invocation has to allow Native client (auto is also possible) and it should start in fullscreen to prevent opening windows.

Hardware

  • Suspend on UD10 is disabled.
