For another data point, try

	export LIBGL_ALWAYS_INDIRECT=1

before running the glxinfo command.

It's possible that there's an issue which only affects direct
rendering. ssh -X localhost would prevent that (although I don't know
why running as root would; perhaps the issue is something in your
environment which is fixed by "su - ..." rather than by running as
root per se).
