So nothing actually changed... Did you try to reboot to get the changes applied ?

Re: Salome_Meca V2019.0.3_Ubuntu 18.04 Installation Issues

I'm out of solutions, there is really something not right with the your opengl and mesa libraries.

The only thing I can recommend to make salome work (with software rendering) is to follow page 2 of the recommended installation procedure (follow the steps as if you were in a virtual machine), this will override the mesa libs with ones compiled specifically for salome.

You won't get 100% of your GPU capacity, but it should still be ok for limited size models (~100k elements is ok).

Good luck

Did you try the procedure of page #2 ?

code-aster.org/spip.php?article1112

This installs a specific mesa version that should make salome meca work without hardware acceleration.

Re: Salome_Meca V2019.0.3_Ubuntu 18.04 Installation Issues

The following worked on our machines - and (cross my fingers) this seems like a very stable SMECA.  Doing a simple case I was able to generate a simple geometry, add groups, mesh it, add the mesh groups, move into ASTER Study, use the Assistant, run the case, then PostProcess and then I went back to Geom, Smesh, Shaper - then back to AsterStudy, then back to PostProcess - all without crashing (I have never been able to do this before without a crash).

Re: Salome_Meca V2019.0.3_Ubuntu 18.04 Installation Issues

Hi,
It seems you have not installed some prerequisite, may be the net-tools. Please install all the prerequisites carefully and try a fresh install of Salome-Meca.
Hope this helps.

Best wishes
