Resolved Issues

Citrix

  • With CWA 2012 Citrix has revised the client drive mapping, with which we can no longer preset the right of the drives. Since then, the user can assign these rights in the session itself. So that this selection remains also over a reboot, we store the necessary file persistently on our system.
  • Updated window manager so that the proxy Authentication window comes to the foreground and is focused when the Citrix Brower content redirection with Cef is used.
  • Fixed window settings for Citrix Desktop sessions
  • Added parameter for Browser Content Redirection with CEF to enable global proxy support.

Parameter

Browser content redirection with CEF via proxy

Registry

ica.module.virtualdriver.webpageredirection.cef_proxy_env

Value

true (default) / false

  • Fixed multimedia support for Citrix when used HWA in Firefox.
  • Fixed high CPU load in MS Teams and Citrix Workspace App 2112.

OSC Installer

  • Fixed OSC Recovery with enabled "Migrate Old Settings"
  • Fixed OSC issue with bogus character in license type field and not shown addon licenses.
  • Fixed returning to installer after closing Factory ID window.

AVD

  • Added several performance optimizations.

RDP/IGEL RDP Client 2

  • Fixed wrong error message when RDP session was closed by idle timeout.

RD Web Access

  • Fixed RD Web Access windows moving out of the screen.
  • Fixed downloading published applications.

Parallels Client

  • Fixed multi-monitor issues.

X session (Xephyr)

  • Fixed segfault with xdmcp sessions to an OpenVMS environment.
  • Fixed fullscreen and workarea x sessions that are expanded over 2 or more monitors: The session window opens properly and the single monitors are detected inside the x session.
  • Fixed host chooser button events in x sessions with connection type "indirect via localhost".

Firefox

  • Fixed usage of Athena IDProtect smartcards.
  • Fixed usage of IGEL extensions when private browsing is enabled. These are important to set restricted kiosk mode settings.
  • Fixed installed translations for user interface.
  • Fixed download prevention with restricted / hidden file system access. Without the fix, the current browser implicitly put the file into the standard Downloads folder - without the possibility to interfere.
  • Fixed crash which always occurred during the internal probing of 3D support for WebGL. So WebGL is now available again for the supported display drivers.
  • Fixed client certificate management via IGEL TC Setup. Firefox's standard certificate dialog is used now.

  • Changed applying of remote settings received during boot - the settings are synced with the current local settings at the end of the boot process. If these changes require a system interaction to be applied (like restart of some services) then the user is asked about applying. The dialog is optional and quits after a timeout. This bugfix solves the problem, that the "Apply changes" dialog is shown on every boot.
  • Fixed evaluation of the exit status of a UMS generic job if the corresponding generic command is implemented as a systemd service.

IGEL Cloud Gateway

  • Fixed exchange of the ICG certificate chain.

VNC

Known Issues

Citrix

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

Parameter

Activate workaround for dual RTME sessions and H264 acceleration

Registry

ica.workaround-dual-rtme

Range

enabled / disabled (default)

  • This workaround is not applicable when "Enable Secure ICA" is active for the
    specific delivery group.
  • Adding smartcard readers during running / active session does not work. The reader is visible, but cannot be used due to unknown reader status. Only relevant for CWA versions earlier than 2112.
  • There are known issues with GStreamer 1.0 in combination with Citrix. These occure with multimedia redirection of H.264, MPEG1 and MPEG2. (GStreamer 1.0 is used if browser content redirection is enabled active.)
  • Browser content redirection does not work when DRI3 and hardware accelerated H.264 deep compression codec is enabled.
  • Enabled DRI3 on an AMD GPU with enabled Citrix H.264 acceleration could lead to a freeze. Selective H.264 mode (API v2) is not affected from this issue.
  • 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"**.
  • Currently H.264 for Citrix sessions cannot be used in parallel with video input acceleration.

OSC Installer

  • OSC not deployable with IGEL Deployment Appliance: New version 11.3 is required for deployment of IGEL OS 11.06. and later.

VMware Horizon

  • After disconnect of an RDP-based session, the Horizon main window which contains the server or sessions overview, cannot be resized anymore.
  • Copying text from Horizon Blast sessions is not possible.
  • The on-screen keyboard in Horizon appliance mode does not work correctly with local logon.
    It is necessary to switch off local logon and enable the following two keys via IGEL registry:
    userinterface.softkeyboard.autoshow
    userinterface.softkeyboard.autohide
  • Zoom VDI Media Plugin versions below 5.8.0 make Horizon Client crash upon connection to the remote desktop in cases when TCSetup is running at the same time.
  • With usage of PCoIP protocol, the virtual channel provided by VMware used for serial port and scanner redirection could freeze on logout from remote session.

This happens only with enabled scanner or serial port redirection.
The freeze does not occur if both redirection methods are enabled or none of them. The Blast Protocol is not affected by this bug.

The respective settings can be found in the IGEL Registry:
vmware.view.enable-serial-port-redir
vmware.view.enable-scanner-redir * Keyboard Input Source Language Synchronization works only with usage of local layout and deadkeys enabled.
If a keyboard layout is used which has deadkeys disabled (which is the default on IGEL OS), Horizon client falls back to en-US layout. * PCoIP sessions may crash in some cases, switch to Blast Protocol is recommended then. H.264/HEVC encoding can be disabled when overall performance is too low. * Client drive mapping and USB redirection for storage devices can be enabled at the same time, but this could lead to sporadical problems.
Horizon Client tracks the drives which are dynamically mounted and adds them to the remote session using client drive mapping, means USB redirection is not used for theses devices then.
However, in case of devices like USB SD card readers, Horizon does not map them as client drives but forcefully uses USB-redirection which results in an unclean unmount.
As a work-around, the IDs of these card readers can be added to IGEL USB access rules and denied.

Parallels Client

  • Attached storage devices appear as network drives in the remote session
  • USB device redirection is considered as experimental for the Parallels client for Linux

Firefox

  • With enabled Citrix Browser Content Redirection, Firefox has no H.264 and AAC multimedia codec support. Means, when codec support is needed in Firefox, BCR needs to be disabled. Citrix Browser Content Redirection is disabled by default.

Network

  • Wakeup from system suspend fails on DELL Latitude 5510

WiFi

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

Cisco JVDI Client

  • There may be a segfault shown in the logs (during logout of Citrix Desktop session). Occurs only when using Citrix Workspace App 2010 and Cisco JVDI.

Base system

  • Hyper-V (Generation 2) needs a lot of memory (RAM). The machine needs a sufficient amount of memory allocated.
  • Update from memory stick requires network online state (at least when multiple update stages are triggered / necessary)

Conky

  • The right screen when using multiscreen environment may not be shown correctly.
    Workaround: The horizontal offset should be set to the width of the monitor (e.g. if the monitor has a width of 1920, the offset should be set to 1920)

Firmware update

  • On devices with 2 GB of flash storage it could happen that there is not enough space for updating all features. In this case, a corresponding error message occurs. Please visit [https://kb.igel.com/igelos-11.04/en/error-not-enough- space-on-local-drive-when-updating-to-igel-os-11-04-or-higher-32870765.html] for a possible solution and additional information.

Appliance Mode

  • When ending a Citrix session in browser appliance mode, the browser is restarted twice (instead of once).
  • 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.
  • Browser Appliance mode can fail when the Web URL contains special control characters like ampersand (& character).
    Workaround: Add quotes at the beginning and the end of an affected URL. E.g.:
    'https://www.google.com/search?q=aSearchTerm&source=lnms&tbm=isch'

Audio

  • IGEL UD2 (D220) fails to restore the volume level of the speaker when the device used firmware version 11.01.110 before.
  • Audio jack detection on Advantec POC-W243L does not work. Therefore, sound output goes through a possibly connected headset and also the internal speakers.
  • UD3-M340C: Sound preferences are showing Headphone & Microphone, although not connected.

Multimedia

  • Multimedia redirection with GStreamer could fail when using Nouveau GPU driver.

Hardware

  • Some newer Delock 62599 active DisplayPort to DVI (4k) adapters only work on INTEL-based devices.

Remote Management

  • AIT feature with IGEL Starter License is only supported by UMS version 6.05.100 or newer.
