# XVFB-RUN PATCHES
Here are patched versions of /usr/bin/xvfb-run to allow multiple xvfb-run processes on one machine.
#!/bin/sh
#######################################################################
#
# 17-sep-2013: the original script does not properly check the existence
# of sockets belonging to previous instances of Xvfb. The wrong display
# is thus assigned, causing execution to fail. The following line has
# been modified below to fix that:
#
# < while [ -e /tmp/.X11-unix/X$i ]; do
# ---
# > while [ -f /tmp/.X$i-lock ]; do
#

# with that server available, and kills the X server when done. The return
# value of the command becomes the return value of this script.

--server-num
-e FILE --error-file=FILE file used to store xauth errors and Xvfb
output (default: $ERRORFILE)
-f FILE --auth-file=FILE file used to store auth cookie
(default: ./.Xauthority)
-h --help display this usage message and exit
-n NUM --server-num=NUM server number to use (default: $SERVERNUM)
-l --listen-tcp enable TCP port listening in the X server
-p PROTO --xauth-protocol=PROTO X authority protocol name to use
(default: xauth command's default)
-s ARGS --server-args=ARGS arguments (other than server number and
"-nolisten tcp") to pass to the Xvfb server
(default: "$XVFBARGS")

before running COMMAND (default: $STARTWAIT)
