HDX RTME on Ubuntu MS Teams not optimized


Did someone get HDX RTME work on Ubuntu ? I've installed Citrix Worspace App 2204 and HDX RTME 2.9.500 on my Ubuntu 20.04 LTS.
But using MS Teams it's showing "Citrix HDX not connected".


Checking the installation via /opt/Citrix/ICAClient/util/hdxcheck.sh showes correctly configured HDX optimization:


-- Checking Microsoft Teams Optimisation Support ... --
Success! libc++ is installed. Please ensure libc++(>=9.0) for proper functioning of Optimisation for Microsoft Teams
Success! libunwind is installed. Please ensure libunwind(>=12.0) for proper functioning of Optimisation for Microsoft Teams


Has anyone success on using RTME on Linux ?

Found it in another thread, it was a missing libunwind.so.1, what was installed by  libunwind-12 using these commands:



Look here:



Adding the libunwind-12 library dependency for llvm-12

Starting with the 2111 release, a new dependency called the libunwind-12 library is added for llvm-12. However, by default, it does not exist in the original repository. Install the libunwind-12 library manually in the repository using the following steps:


$ wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key|sudo apt-key add


$ sudo vi /etc/apt/sources.list


Add the following line:

deb http://apt.llvm.org/bionic/ llvm-toolchain-bionic-12 main deb-src http://apt.llvm.org/bionic/ llvm-toolchain-bionic-12 main


$ sudo apt-get update 

$ sudo apt-get install libunwind-12
