Known Issues 11.02.130

Citrix

• With activated DRI3 and 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.
• 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".

• To launch multiple desktop sessions with Citrix HDX RTME and Citrix H.264 acceleration plugin, the following registry key must be enabled:

  More...

  Parameter	Activate workaround for dual RTME sessions and H264 acceleration
  Registry	ica.workaround-dual-rtme
  Value	enabled / disabled

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

VMware Horizon

• Sound redirection in PCoIP is broken when the so-called lightweight-client is used, which has become the new default.
  Sound redirection can still be used by choosing the rollback-client instead. This can be done by setting the IGEL Registry key:

  More...

  Parameter	Allow rollback to former client variant
  Registry	vmware.view.allow-client-rollback
  Value	enabled / disabled

• 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.
• 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.

WiFi

• TP-Link Archer T2UH WiFi adapters do not work after system suspend/resume.
  Workaround: Disable system suspend under IGEL Setup > System > Power Options > Shutdown.

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 once with disabled FIPS support.

Smartcard

• In seldom cases, the authentication hung 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 should be started in fullscreen to prevent any opening windows.

Multimedia

• Multimedia redirection with GStreamer could fail with the Nouveau GPU driver.

Audio

• IGEL UD2 (D220) fails to restore the volume level of the speaker when the device used firmware version 11.01.110 before.
