====== Xubuntu as a Windows XP (ChromeOS like) Replacement ======

===== Basic Setup =====

  - install Xubuntu 14.04
  - Download and install [[http://www.google.com/chrome|Google chrome]]
  - Install supporting packages<file>
apt-get install vim mercurial tuxpaint tuxpaint-config libreoffice
</file>
===== Create User Account =====

  - customize default user to your liking, create a new user or use the account created during install
  - execute the following commands remember to enter a log message after hg commit.  If you make changes to your user update the template by running hg addremove and hg commit again<file>
hg init
hg addremove
hg --config ui.username=foo commit
</file>
  - Create the session script in /scripts/custom_session.sh<file bash /scripts/custom_session.sh>
#!/bin/sh

cd ~
hg revert --all
hg --config extensions.purge= purge 
startxfce4
</file>
  - Create a new login session by creating /usr/share/xsessions/custom_session.desktop<file desktop /usr/share/xsessions/custom_session.desktop>
[Desktop Entry]
Version=1.0
Name=School Session
Comment=Use this session to run Xubuntu as your desktop environment
Exec=/scripts/custom_session.sh
Icon=
Type=Application
</file>
  - You now can select **School Session** from the login manager and it will revert your home directory to the state it was the last time hg commit was run

===== Other Recommendations =====
  * add a startup application script to start chrome at a google login page<file bash /scripts/chrome_login.sh>
#!/bin/sh

google-chrome "http://g.sebeka.k12.mn.us"
</file>
  * you can remove the Application menus from the panel and desktop menu
  * sub pixel hinting is not enabled by default, enable to enhance font rendering on LCD displays
  * mercurial will delete empty directories on purge, run "touch .desktop" to create a empty hidden file
  * you can remove a password from a user by running, be sure to enable the root user if you only have one user<file>
passwd -d <USERNAME>
</file>
  * mercurial stores the home directory template in ~/.hg

===== Tuxpaint =====
  * tuxpaint uses lpr for printing so ${PRINTER} must be set, use lpstat -p to see a list of printers
  * use tuxpaint config to set tuxpaint options
