Nino Mint - XFCE Desktop for Spanish Education

Nino Mint Project     Learn - Play - Do - Build - Grow

Linux for Install on Older Computers for Educational use in Central America and Carribian

(work in progress)  
Based on the success of my last build (see this link) plus enhancements like locking down some settings (aka partial Kiosk mode) and including a reset script.

I decided for my current build to utilize Linux Mint Debian (LMDE) 32 bit with XFCE windows manager.  This will hopefully allow me in months and years ahead to update the build without starting from scratch.  XFCE will also allow some nice features like Kiosk Mode.  I am planning to implement some of Kiosk mode features combined with a RESET script to restore desktop areas which I do not lock.  Another idea is to setup a pre-configured server with PXE boot support and Clonezilla loaded with an original image, so they can completely reformat the computers when needed.

Without further ado, below are the steps I took to create a full featured, ready to use system for distribution on refurbished computers.

    Users and Groups
    • Setup the following users via system/users and groups/add user
      • maestra: Installed with this user, will be utilized by instructors
      • listo: User for general use by students
      • itadmin: Reserved for IT admins only
      • adelante: Rarely used by students or staff with laptops
        (change password for each separate machine)
    • Advanced User Settings
      • Under system/users and groups, then advanced settings/user privileges 
      • All users should have all priveleges checked 
      • EXCEPT listo user should NOT have "administer the system", "monitor system registries", or "configure printers" checked
    • Groups - Select Manage groups (from the users Settings app) and make the following changes
      • adm - select all users EXCEPT listo
      • admin - create and select select all users EXCEPT listo
      • sambashare - select all users EXCEPT listo
      • ssh - select itadmin only
      • staff - select maestra and itadmin only
      • sudo group - select all users EXCEPT listo
      • users group - select all users
      • vboxuser - select all users
        • must be done after installation of virtualbox
    Directories for Shared Files
    Make the following directories for shared file location
    • /share  -- used to hold shared information via the following subdirectories
      • sudo mkdir /share
    • /share/basic
      • sudo mkdir /share/basic
    • /share/biblia
      • sudo mkdir /share/biblia
    • /share/foto
      • sudo mkdir /share/foto
    • /share/musica
      • sudo mkdir /share/musica
    • /share/wiki
      • sudo mkdir /share/wiki
    • /share/admin
      • sudo mkdir /share/admin
    Now modify rights on these directories
    • /share rights - I want itadmin as owner with associated group as users (-R command makes it recursive to all subdirectories)
      • sudo chown -R itadmin.users /share
    • change rights so all users can read, write and execute files in these directories
      • sudo chmod -R a+rwx /share
    • Add sticky bit on these directories which disallows different users from renaming or deleting another users's files or directories.  That way we can add content as itadmin or maestra that all users can access, but cannot delete or modify (e.g. bible and wiki files).
      • sudo chmod -R +t /share
    • Verify the directory structure... should be as follows
      • sudo ls -l /share
    • change rights on /admin directory .....
    drwxr-xr-x  2  itadmin itadmin..... admin
    drwxrwxrwt 2 itadmin users ....... basic
    drwxrwxrwt 2 itadmin users ....... biblia
    drwxrwxrwt 2 itadmin users ....... foto
    drwxrwxrwt 2 itadmin users ....... musica
    drwxrwxrwt 2 itadmin users ....... wiki

    Additional Program Setup Steps 
    Programs that need additional setup to work perfectly

    • Basic256 - help files not fully included by default, plus add examples to share directory
      • go to and download the latest program file
      • unpack download file into Descargas/basic directoy
      • Copy the 'help' folder to /usr/share/basic256/ and check correct ownership and permissions... after first removing the broken help files
        • sudo rm -R /usr/share/basic256/help
        • cd ~/Descargas/basic
        • sudo cp -R ./help /usr/share/basic256/  
          (this may not work in later version of the program)
        • ls -l /usr/share/basic
      • Copy the Examples directory into /share/basic/examples
        • sudo cp -R ./Examples /share/basic/
      • Copy the program icons
        • sudo cp ./resources/images/basic256.png /usr/share/basic256/
        • sudo cp ./resources/images/basic256.ico /usr/share/basic256/
      • Change menu to use the icon
        • gksudo gedit /usr/share/applications/basic256.desktop
          • change Icon= line to read
          • Icon=/usr/share/basic256/basic256.ico
        • save file
    • Kiwix - the latest Kiwix does not readily install, here are the steps I needed to take
      • log in as itadmin 
      • Download Latest GNU/Linux version if Kiwix program from here:
      • From the same site, also download the Spanish language zim file (10Gb for March 2012 build)
        • test file with md5:
        • md5sum /home/itadmin/Descargas/wikipedia_es_all_03_2012.zim
        • checks out equal to sum listed on web site
      • move to share directory (in terminal)
        • mv /home/itadmin/Descargas/kiwix[.....] /share/wiki
      • move zim file to share directory
        • mv /home/itadmin/Descargas/wiki[...] /share/wiki
      • unpack program
        • tar xvjf /share/wiki/kiwix[...].tar.bz2 -C /share/wiki
      • remove original tar file
        • rm /share/wiki/kiwix[...].tar.bz2
      • tested kiwix program by navigating to /share/wiki/kiwix/kiwix and double clicking on it (it is executable)... success
      • Add a menu item for kiwix for all users
        • in terminal go to /usr/share/applications directory
          • cd /usr/share/applications
        • copy klavaro.desktop as kiwix.desktop
          • sudo cp klavaro.desktop kiwix.desktop
        • edit file
          • sudo nano kiwix.desktop
          • change the following lines
            • Name=Wikipedia_Kiwix
            • Comment=Offline Encycolpedia Browser
            • Comment(es)=Encyclopedia Wikipedia Local
            • Exec=/share/wiki/kiwix/kiwix
            • Icon=/share/wiki/kiwix/xulrunner/chrome/icons/default/default16.png
          • ctrl-o to save, then ctrl-x to exit
        • Try running program from menu.... Fails with permission issue (also icon did not show up
          • look at directory permissions... 
          • cd /share/wiki
          • ls -l
            • shows kiwix owned by itadmin with owner permissions, but no permissions for group or other users....
            • of course this is because of sticky bit.... tricky
        • Correct permission issues by applying different permissions
          • sudo chmod a+rx -R /share/wiki/kiwix
          • Check permissions with ls -l on this directory
          • Shows read and execute permissions for all users
        • Try to launch from menu again -- success
        • Log out and try to launch from menu as listo user -- success
      • Build the index for listo user

    • Turn numbers lock on automatically (seems to be no way to select it in a menu, so install a little program to run at start) - only done once
      • in terminal
        • sudo apt-get install numlockx (or use software manager)
    • Remove Unnecessary Grub Boot Menu Options - after several kernel options propogate in the boot menu, it may get busy.  The easiest way to clean this up is to remove the older, associated packages linux-header-[kernel version & architecture] and linux-image-[kernel version & arc.].  This removes the older kernels and grub, stops listing them as boot options.
      • open synaptic package manager
      • search for older linux-image and linux-header packages (3 for each kernel version)
      • mark for complete removal

    Move or Hide Menu Items for Programs
    Hide the following programs as shown below:

    Hide these by copying the .desktop file into local directory, then changing this file so it doesn't show the program in the menu.  This does not remove the program, just hides it.  Alternately, the program can be disallowed.

    Add Kiosk Mode and Reset Script Functionality
    Add functionality so it is hard to modify desktop beyond point of usable... and ability to reset for listo user.  Possibly make desktop reset automatic on start-up (would be very useful in classroom setting).  Also hide some menu items for some users.

    Regarding a startup script which would reset the panel and other desktop settings, there seem to be a couple good suggestions (see additional resources below).  Namely Cron jobs and a special start-up script.  Since Cron jobs are ubiquitous across just about all Linux distros, this seems like a good method.  Also, one can create a script which can be potentially run at another time and from a directory that itadmin user has rights to making it easy for modifying or replacing the script or adding other maintenance scripts with different functionality.

    Scripts desired

    - desktopsave -- will be used to save desktop configuration for user listo
    • Will need to be run as itadmin user, otherwise will not be able to write to config backup directory
    - desktopreset -- will be used to reset desktop configuration for user listo
    • Should be allowed to run as any user
    Script Setup Steps
    • Create Directory (from terminal as itadmin user)
      • sudo mkdir /share/admin
      • cd /share
      • ls -l  (to see what it looks like)
      • sudo chown itadmin:itadmin /share/admin
      • ls -l (gives output like this which is good)
        • drwxr-xr-x 2 itadmin  itadmin  4096 date time admin
    • Create save to directory (as itadmin user)
      • cd /share/admin
      • mkdir homesave
    • Create desktopsave script file
      • cd /share/admin
      • touch desktopsave
      • ls -l
      • chmod u+x desktopsave
      • ls -l
        • this gives... -rwxr--r-- l itadmin itadmin date time desktopsave
        • file is writable and executable by itadmin user only but readable by all.  This way other users cannot execute this program and save a bad configuration.
    • desktopsave script... edit in your favorite browser and add the following lines
      • #!/bin/bash
      • # desktop save script, used to save listo user configuration
        • this first line is standard for scritps, second line is a comment
      • cd /share/admin/homesave
      • # delete the previous backup
      • rm -r /share/admin/homesave/listobak
      • # make a copy of the current backup
      • cp -r /share/admin/homesave/listo /share/admin/homesave/listobak
      • # delete the current backup
      • rm -r /share/admin/homesave/listo
      • # copy listo home directory (.config and .local only for now)
      • mkdir /share/admin/homesave/listo
      • cp -r /home/listo/.config /share/admin/homesave/
      • cp -r /home/listo/.local /share/admin/homesave/
      • # make readable to all users
      • chmod -R a+r /share/admin/homesave/listo
        • this is not really necessary based on permissions on the homesave directory, but I include it in case these permissions get changed
    • Create desktopfix script file
      • cd /share/admin
      • touch desktopfix
      • chmod a+x desktopfix
      • ls -l
        • this shows file is readable and executable by anyone, but only itadmin can write to it, so any user has the rights to run this script to reset the listo user desktop
    • desktopfix script... edit in your favorite browser and add the following lines
      • #! /bin/bash
      • # desktop reset script
      • # just copy configuration and local directories (for now) other files can be manually copied if needed
      • rsync -r --delete /share/admin/homesave/listo/.config /home/listo/
      • rsync -r --delete /share/admin/homesave/listo/.local /home/listo/
      • # the following restarts the bottom panel if it was closed
      • #xfce4-panel         commented out - doesn't work well in script
      • # the following only applies to older xfce 4.2, starts taskbar if stoppped
      • #xftaskbar4           commented out - for older xfce
      • # the following only for xfce 4.4 lus, reloads windows manager (if borders missing on programs)
      • xfdesktop
    • desktopfixlistomenu script... edit in your favorite browser and add the following lines
      • similar to the above script, except rsync lines are commented out and the xfce4-panel is not
    Create Menu items for desktopfix and desktopsave scripts  
    The following menu items are desired:
    For listo user - REPARAR DESKTOP

    For itadmin user - REPARAR DESKTOP
                               - GUARDAR DESKTOP

    • Copy .desktop programs to appropriate users to use as templates and change ownership of files
      • sudo cp /usr/share/applications/gparted.desktop /home/listo/.local/share/applications/reparar.desktop
      • sudo nano /home/listo/.local/share/aplications/reparar.desktop

    Problem Resolution - common

    • Disappearing [start] panel, desktop or windows borders
      Because Xfce is modular, each of these can be inadvertently stopped, removed or crashed.  Type the following command into terminal (Alt-F2), depending on the missing item.  You may need to choose "Save session for furue logins when shutting down to make changes permanent.
      • Panel (start bar) missing --> xfce4-panel
      • Taskbar missing --> xftaskbar4  (xfce4.2 only)
      • Windows Manager missing (no borders on programs) -->xfdesktop (xfce 4.4 only)
    • Video not working smoothly - may need to change video drivers

    TO DO: For future Releases

    • Local update repository... for updating all computer without using Internet bandwidth.  Probably should be added to the Zentyal server, maybe using virtual server
      • found this tip:  install apt-proxy or approx on a server... maybe directly on Zentyal server, then can either configure each computer to point to Zentyal or maybe even configure the Zentyal server to send all update requests to it!  
      • This caches all updates on the apt-proxy or approx server and keeps individual computers from downloading updates from the Internet.
    • Deployment/reinstall system
      • Clonezilla server.. side by side with Zentyal or as a VM under Zentyal (most secure)?
      • Clonezilla on DVD or USB boot?
      • remastersys?  limited to 4GB, I believe
    • Configuration management program on server options include:
      • Puppet - or another auto configuration management program. Need to research and test first
    • Monitoring server program, e.g. Nagios?
    • Other Games Possibilities from
      • Xonotic (was Nexuiz) -best in breed free fps
      • Voxelands - minecraft clone
      • The Dark Mod - like theif
      • Tales of Maj'Eyal (ToME) - a roguelike RPG
      • 0 A.D. - like Age of Empires II
      • Supertuxcart
      • Hedgewars - like worms

    Stuff Tried, but not Kept
    Games and Programs which were tried, but did not work with either this configuration or the age of computers I am using.
    • Play on Linux: ... There are too many good games being ported to Linux, this is no longer critical to include.
    • Educational: Stellarium (did not open), Celestia (slow), Pysycache (slow kids program)
    • FPShooters: Hedgewars, Nexuiz, Sauerbraten, Alien arena, AssaultCube
    • Board Games: BrutalChess, DreamChess, LondonLaw, Mah-jong (complicated), Pychess, Quarry (complicated), 
    • Strategy Games: rott-Rise of the Triad (fails to start), Warzone 2100, pioneers (complicated), stroq (hard to understand), Widelands (slow),  
    • Archade Games: Blockout II (3d tetris, doesn't load), Zaz (doesn't load), 
    • Platform Games: SMC (campy mario nock off), 
    • Other: Flightgear (very large), Supertuxkart (slow), Titanion (fails to load), Frets on Fire (crashed), Oolite (hangs), Wormux (nice game, but hangs when quitting), rrotage (couldn't figure out how to play)
    • Those which would be worth trying on better hardware:
      • Widelands
      • Liquidwar
    • Dosbox... not installing this program which allows playing of old DOS games since this is no longer relevant, especially for better quality hardware
    • TuxGuitar - unable to figur out midi backend... tried installing Timidity, qmidiarp, qjackctl as options, then selecting in TuxGuitar... hmmm, I don't really understand this midi stuff, giving up for now.
    • Chemestry... Chemtool, EasyChem, GDIS Molecule modeler, ghemical, PyMol, and Viewmol (GChemPaint was chosen instead)
    • Games that were good or decent, but just had too many already
      • Berusky - lazy bug puzzle game
      • Konquest - complex strategy game
      • lTris - tetris clone, but I liked quadrapazzel better
      • Xmoto - 2d motorcross game - still needs just a bit of development work, was missing some levels
    Obsolete Instructions from Previous version - now fixed or not aplicable

    • Childsplay - To get Childsplay to use Spanish alphabet sounds, need to specify at launch by changing the menu launcher as follows.
      • program needs to launch with the following command (caps important)
      • LANGUAGE=es childsplay
      • tested from command line... honestly the Spanish tract is not that great, hmm maybe I should keep it in English... learning English numbers not so bad ?
    • BibleTime
      • Bibletime is crashing when installing bibles and references... 
      • This is a bug in the Sword module... easiest solution may be waiting for bug fix, then installing it
      • currently on libsword8 1.6.2 + dfsg-1 and bibletime 2.8.1-2
