[visit-developers] OpenGl driver compatibility?

You need Mesa if you will be rending on a machine without a display. So if your remote server doesn't have any type of display then that may be your problem.

Hi Eric,

Yes Linux.

Actually, your builds work fine on other machines, but ours do not.  We are not building with Mesa.  So we are trying to figure out why our build of VisIt does not work while yours does.

What are the use cases for having Mesa?  Does one need it for remoting?

Any other ideas on how this incompatibility arises?

For 2.9.2, the Ubuntu 11 version comes in 2 versions, with and without Mesa, the Ubuntu 14 version is without Mesa, and the rhel6 version is with Mesa. For future releases I will also generate 2 versions for the thel6 version, one with Mesa, one without.
