 ==== Firefox touch events ====
-Seems firefox lacks support for proper touch events.
+It seems that firefox lacks support for proper touch events.
 use chromium instead.
+===== Chromium Kiosk Mode =====
+In kiosk mode the user has limited access to the computer,
+only one fullscreen application allows interaction with the system.
+=== openEASE session ===
+Login managers are starting sessions after a user logs in.
+Such sessions usually start a window manager and possibly other
+default software services.
+in case of openEASE we only need a running web browser.
+Since firefox has issues with touch events we have to stick with chromium for now.
+Make sure chromium is installed:
+  sudo apt-get install chromium
+A window manager seems required. I prefer using a lightweight manager such as **xfwm4**.
+Make sure the WM is installed:
+  sudo apt-get install xfwm4
+Sessions are defined in .desktop files.
+Create a new openEASE session at **/usr/share/xsessions/openease.desktop** with following content:
+  [Desktop Entry]
+  Name=openEASE
+  Comment=This session logs you into openEASE
+  Exec=/usr/bin/openease.sh
+  Icon=
+  Type=Application
+  X-LightDM-DesktopName=Chromium
+  X-Ubuntu-Gettext-Domain=gnome-session-3.0
+**TODO** include openEASE icon
+The session references a shell script **/usr/bin/openease.sh**. Create this file with following content:
+  #!/bin/bash
+  xfwm4 &
+  xscreensaver -nosplash &
+  sleep 3
+  chromium-browser --app=https://data.open-ease.org --kiosk
+The session should now appear in the list of sessions in the login manager.
+=== Login Manager ===
+First create/select a dedicated unix user for guests and allow the user to
+log in without password:
+  sudo gpasswd -a guest nopasswdlogin
+Now make openEASE the default session of the system by editing **/etc/lightdm/lightdm.conf**,
+adding these lines:
+  [SeatDefaults]
+  user-session=openease
+  greater-show-manual-login=true
+=== Screensaver ===
+Install xscreensaver from ubuntu packages:
+  sudo apt-get install xscreensaver
+Start xscreensaver for configuration:
+  xscreensaver-demo
+Set the blank time to something reasonable such as 10 minutes.
+Then, kill the screensaver:
+  killall xscreensaver
+Open configuration file at *~/.xscreensaver* and add following "program":
+		    "openEASE" 	mplayer -shuffle -nosound -really-quiet	      \
+				  -nolirc -nostop-xscreensaver -wid	      \
+				  $XSCREENSAVER_WINDOW -fs -loop 0	      \
+				  $HOME/Videos/*			    \n\
+This "program" can be used to show videos that are available in the directory
+~/Videos/ while no one is using the touch screen.
+To select the video loop, open *xscreensaver-demo* again, select "Just one screensaver"
+and select "openEASE" from the list of screensavers.
