Known Issues 11.09.210
Citrix
- 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.
- Browser Content Redirection (BCR) does not work if DRI3 and hardware accelerated H.264 deep compression codec is enabled.
- 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.
While starting Self-Service, it is possible that process ServiceRecord segfaults -> Self-Service cannot be started afterwards.
A cache cleanup with reboot is needed. In addition, the following parameters should set to true.- Browser Content Redirection (BCR) may not work with Chrome version 105.0.* or later. See https://support.citrix.com/article/CTX473065/hdx-browser-content-redirection-broken-with-google-chrome-browser-version-105-or-higher
- White / green fragments may appear during desktop launch if JPEG graphical codec is used.
- MS Teams calls may stop if blurred background is enabled. This affects Citrix Workspace App 2305 and later.
- Regarding CVE-2023-41993, CVE-2023-39928 & CVE-2023-41074:
For compatibility with Citrix Self-Service, older Webkit libraries are used instead of the latest ones to continue working properly.
More information: https://wiki.test.toolchain.igel.kreuzwerker.net/securitysafety/en/isn-2023-25-webkit-vulnerabilities-101066782.html - ZoomVDI version 5.16 or newer is no longer supported with Citrix Workspace app 20.10.
- Browser Content Redirection (BCR) may not work with Citrix Worspace app 23.11 and current Chrome versions.
OSC Installer
- OSC not deployable with IGEL Deployment Appliance: Version 11.3 or later is required for deploying IGEL OS 11.06. and following.
AVD
- H.264 hardware decoding for MS-Teams optimization is currently limited to non- AMD devices due to stability issues on AMD devices.
VMware Horizon
- 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.autoshowuserinterface.softkeyboard.autohide - 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-redirvmware.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 sporadic 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
Chromium
- Hardware accelerated video decoding is currently not supported.
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.
- Firefox restart option currently not supported.
Network
- Wakeup from system suspend fails on DELL Latitude 5510
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
- It is not possible to perform an unattended OS12 migration to base system 12.2.0 as an additional / manual reboot is necessary. The recommended upgrade version for unattended migration is base system 12.2.1.
- Due to suspend/resume issues of a Innodisk NVME we disabled the suspend support for systems where this NVME is present. The issue otherwise will lead to a complete loose of the storage device as the NVME will not work after resume.
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 4 GB flash storage or smaller it could happen that there is not enough space for updating all features. In this case, a corresponding error message occurs. Please visit https://wiki.test.toolchain.igel.kreuzwerker.net/igelos-11.09/en/error- not-enough-space-on-local-drive-when-updating-to-igel-os-11-08-or- higher-101059051.html for a possible solution and additional information.
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.
- 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
- UD3-M340C: Sound preferences are showing Headphone & Microphone, although not connected.
Multimedia
- Multimedia redirection with GStreamer could fail when using Nouveau GPU driver.
Hardware
- Wake up from suspend via UMS does not work on HP mt645 devices. Workaround: Disable system suspend and use shutdown instead.
- Built-in fingerprint sensor is not supported on HP mt440 and mt645.
- MAC-Address Passthrough not supported on Lenovo USB-C Hybrid Docking Station.
- Wake-on-Lan via docking stations is not supported.
- In some rare cases it is possible that connecting or booting Lenovo USB-C Hybrid Docking station over USB-C results in non working / faulty display output.
It may help to (re-)connect via USB-A. If this is the case, USB-C should be also functional then. - Display configuration of displays connected to HP G5 Docking Station may fail with HP t655.
