This indicates the OpenGL library isn't compatible with the X server.

There isn't anything which we can do to fix this, although adding the
"-indirect" switch to the "togl" commands in nviz2.2_script might
eliminate the error at the expense of performance (indirect rendering
doesn't use hardware acceleration on the stock X.org servers).
