headless.txt

 *****************************************************
 * New headless method on ubuntu by using vnc4server
 *****************************************************
 * Tested on Ubuntu 14.04 (hardy) with default gnome
sudo apt-get install vnc4server
 * Create a shared folder with selenium scripts
sudo mv selenium /
sudo chmod 775 /selenium
sudo chmod g+rwx /selenium/*.sh /selenium/chromedriver
 * Create an extra user
sudo adduser --gecos "" --ingroup user user2
 * Impersonate user2 to avoid logoff. -x to disable X11 fwd
ssh -x user2@localhost
 * Generate initial config files
vnc4server :2
 * Stop vnc server to edit files
vnc4server -kill :2
 * Comment line `x-window-manager &` and add your selenium start script, e.g.
vim .vnc/xstartup
 * selenium start scripts examples
x-terminal-emulator -geometry 120x30+10+10 -ls -title "$VNCDESKTOP Desktop" -e "/selenium/chrome-to-grid-6666.sh" &
x-terminal-emulator -geometry 120x30+10+10 -ls -title "$VNCDESKTOP Desktop" -e "/selenium/firefox-to-grid-6666.sh" &
 * Start vnc server with specific screen resolution
vnc4server :2 -geometry 1400x988
 * Repeat for as many users as you want
 * How to automate the startup process
sudo mkdir -p /etc/headless
sudo vim /etc/headless/vncservers.conf
