Salome 8.2.0 stopped to work after ubuntu 17.04 update

Hi,

I use Salome 8.2, it worked very well until an update of my ubuntu (17.04), unfortunately I didn't pay attention to what packages have been changed, and my packages log file of last upgrades didn't tell me more....

A direct execution of salome gives the following error :

------------------------

--- Error during Salome launch ---
-------------------------

when I execute salome as a root (sudo), I get the GUI but it crashes after the call of the geometrical module. It gives the following error:

$ Terminating SALOME on port 2824...
---------------------------

Have you please any idea about how to solve this problem?

on the other hand, I upgraded salome to 7.8 version, I had another problem when I used "Explode" function in the geometrical module, and error dialog box informs me that the lib managing the user GUI is not found...

The cause of the two problems could be the same...

Thanks by advance for your responses.

Finally, my problem has been resolved by installing salome-meca 2017 which contains probably most recent libraries... 

However, the bug I encountered with salome 8.2.0 yet persistes...

Good afternoon.

I installed salome from universal binaries for linux on ubuntu 17.04 and I got a similar problem.

I fixed it changing the video card driver, from open source driver (nouveau) to nvidia (my video card).

Now salome works.

Best regards.
