@julianvargasalvarez you're probably past this after 2 months, but just incase & for others:

install xvfb (e.g. Through apt-get if you're using a Debian system)
put the contents of the gist as a file residing at /etc/init.d/xvfb
you'll probably need to make it executable chmod +x /etc/init.d/xvfb
and then you can start it with /etc/init.d/xvfb start

The script will start the virtual display at :1 so make sure to set your environment variable appropriately (export DISPLAY=:1) before running whatever you want to run inside the virtual x frame buffer.

Hi, just wanted to say thanks, it helped. :)

Thanks for the script. I forked and added LSB init info to this script (would do a pull request but not possible with gists) if you want to add as well go for it

Thanks for this!
After stopping, however, I always receive the error:

Stopping virtual X frame buffer: Xvfbstart-stop-daemon: warning: failed to kill 7865: No such process.

7865 being the process number in the pidfile.

The script doesn't actually stop Xvfb

# /etc/init.d/xvfb start
Starting virtual X frame buffer: Xvfb.
# pgrep Xvfb
# /etc/init.d/xvfb stop
Stopping virtual X frame buffer: Xvfbstart-stop-daemon: warning: failed to kill 7547: No such process       

7547 is value from pidfile. Something goes wrong and process doesn't stop :(

Nice! Totally stealing this.

This did not automatically start Xvfb on boot. Instead, I used and that works.

Very helpfull. Thanks!


Vic-L commented Nov 3, 2015

thx too!

is there a way to also include the

export DISPLAY=":1"

in this script?

This was very helpful, thank you! :)

Thanks this is helpful.
I am using this rather small but efficient like above


if [ -z "$1" ]; then
echo "basename $0 {start|stop}"
case "$1" in
/usr/bin/Xvfb :0 -ac -screen 0 1960x2000x24 &;;
killall Xvfb;;

@amrindertweddle nice, but missing esac

Hi, i started Xvfb and after start tests i received:

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host on port 7055 after 45000 ms. Firefox console output:
XPCOMGlueLoad error for file /home/jenkins/firefox/ cannot open shared object file: No such file or directory
Couldn't load XPCOM.

Firefox 46.01, Selenium 2.53.1
i haven't any problems with the same versions Firefox and Selenium on local machine
any ideas ?
