Comment 9 for bug 516123

This issue seems to have come back in Natty.

I see a slightly different error message than I have seen most people report(in regards to previous versions)

"RandR extension missing"

Trying to get this working in regards to a Minecraft map generator, which has a decent wiki page.
Wiki page shows it worked on Maverick and Lucid, and then stopped working in Natty.

So far as I saw, the upstream bug was never fixed. Perhaps a merge to upstream reverted this?

Please let me know if there is something I can do to provide more useful details, but the basic thing I am doing here is:

xvfb-run -a xrandr

and simply receive the before mentioned error message.
