Ubuntu:
$lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.3 LTS
Release: 14.04
Codename: trusty
Xvfb:
$ dpkg -s xvfb
Package: xvfb
Status: install ok installed
Priority: optional
Section: x11
Installed-Size: 2140
Maintainer: Ubuntu X-SWAT <ubuntu-x@lists.ubuntu.com>
Architecture: amd64
Multi-Arch: foreign
Source: xorg-server
Version: 2:1.15.1-0ubuntu2.7
Provides: xserver
Current problem:
Xvfb do not support RANDR extension, even if I add the flag:
+extension RANDR
If I run xdpyinfo, RANDR is not on the list. It's a missing feature or a bug.
I found a reference here with a patch: https://bugzilla.novell.com/show_bug.cgi?id=823410
And looks like that in other distros like debian, there is already a testing build of Xvfb with support: https://unix.stackexchange.com/questions/205509/running-firefox-in-xvfb-extension-randr-missing-on-display
I am trying to run a program throught Xvfb, and it returns the following error:
Xlib: extension "RANDR" missing on display ":99".
The program works if I run it via ssh/command line. The problem appears to be the the lack of support for "RANDR" in xvfb.
My question is: what is the easiest way to get xvfb with "RANDR" support in my system?

$Xvfb :99 -screen 0 1024x768x24 > /dev/null &
$ xdpyinfo -display :99 | grep "number of extensions" -A 25
