Have you looked at troubleshooting rviz? It is likely you just need to set OGRE_RTT_MODE

The relevant section says:

Various OpenGL or Ogre things can go wrong during startup. One of them seems to relate to the render-to-texture system. Ogre supports 3 different modes, and rviz uses the "PBuffer" mode by default. Some users have reported some modes cause a segfault during startup, but it is not clear which should be used when.

If you have a problem and want to try another "RTT mode", run rviz with the environment variable OGRE_RTT_MODE set to either "Copy", "PBuffer", or "FBO". For example:

export OGRE_RTT_MODE=Copy
