Thanks robert, you mentioned you had also send these patches to the bugzilla upstream at fdo - can you indicate the bug number so we can track it upstream (and encourage upstream to take the patches)?

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.

The patch at:
http://patchwork.freedesktop.org/patch/13852/
still applies, but hasn't been reviewed since it was posted to the mailing-list a year ago.

This patch would be useful to start using Xvfb in gnome-settings-daemon's test suite.

In June 2015 there was another attempt to get this patch merged[0], it seems that people are now recommending/leaning towards replacing xf86-video-dummy[1] by Xvfb[2][3].

The patch looks trivial enough to get merged, but maybe it never will due to Xvfb deprecation (=WONTFIX)?

yes, it seems silly that it hasn't been merged yet considering its simplicity. if people want to deprecate things in the long run, that's fine, but i don't think that should hold up this patch.

    vfb: add randr support (v2)

    The motivation for getting this is chrome remote desktop that runs under
    Xvfb and wants to use RANDR to adjust screen size according to the
    remote desktop client screen size. Apparently there are other use cases
    as well, the bug mentions gnome-settings-daemon testing.
