after installing Salome Salome-V8_4_0-univ_public on Ubuntu 18.04 I faced this problem where I cannot enter new entities like 2D /3D sketch The error message is:
GUI library corresponding to the users action can not be found or loaded.

the terminal has the following message too.

I installed salome meca 2018 on a ubuntu 18.04 which was freshly installed.


I had to install python 2.7 and gcc and install libcanberra-gtk0 libcanberra-gtk-module
finally net-tools.
Also disable 3 faulty drivers at $HOME/salome_meca/V2018/prerequisites/debianForSalome/lib/libstdc++.*


Now Salome Meca 2018 starts with the following warnings:


stefan@ubuntu-engineering:~/salome_meca/appli_V2018$ ./salome

Would be nice if someone had a suggestion on how to resolve these Warnings.
