OpenGL not working on RHEL 6.1
 

I am trying to install a software package called Abaqus, and it is failing during the prereq check with the following message:

Fail: X server is not configured to use OpenGL. Verify that the DISPLAY environment variable is set to an X server that is configured to use OpenGL; otherwise contact system administration to have the X server configured to use OpenGL.

We have the mesa packages installed according to yum. Is there some simple config issue that I missed?

can you please post more information?
like what is this "Abaqus"
a link would help . Google shows
http://www.simulia.com/support/v610/v610_graphics.html
and i have no idea if that IS what you are talking about

also your 3d cards ( if you have any installed )
if Nvidia
rhel6 uses the nouveau open driver for nvidia
and requires a bunch of work to switch to the proprietary nvidia driver ( way more that a few mouse clicks)

It turned out to be a non-issue. The software will actually use the X display of another system when running, whether an X workstation or an Exceed setup on a PC. The check for OpenGL on installation is not really relevant to the way the software will be used.
