salome meca installation Mesa problem

Hy,

I am trying to install salome meca 2018 on a remote machine running under Ubuntu 18.03.
When I launch salome and connect the GEOM module, the screen is black and no shape can be visualized.
The shell reports this message:

OpenGL driver is too old! Context info:
...
Version: 1.3 Mesa 4.0.4

But on this machine Mesa is updated:

ubuntu@ip-172-31-16-93:~$ glxinfo | grep "OpenGL version"
OpenGL version string: 3.1 Mesa 19.2.8

Any hint ?

Regards,
Marco

Re: salome meca installation Mesa problem

Thank's a lot for your quick reply.

I followed the procedure and GEOM runs correctly.
Without graphic acceleration card the GEOM seems very slow in managing the images.
I have to check in my office with a fiber internet connection.

Is there the same procedure for salome meca 2018 ? Googoling I wasn't able to find something similar.

Regards,

Marco

Re: salome meca installation Mesa problem

you hv to run solver from astk or salome shell to get speed.
2018 same procedure of installation, for without graphic card.

Re: salome meca installation Mesa problem

What you mean for run "salome shell" ?

Without GUI ?

If I enforce my AWS EC2 instance with GPU I gain speed in salome meca ?
