Package gnome-watchdog - cleans up gnome user session

[Philipp Hanselmann]

Hi David,

I haven't tested it, but I don't see any reason why it should not work 
with Gusty.

Since we have implemented it the performance of Edubuntu increased!

Maybe have also a look an that script:

http://www.morokeni.ch/edubuntu/start-prog

 The script it's prevents that user starting the same program more than 
once. Is the program already started a message box comes up and informs 
about the already running program. Additionally it's counting how many 
multimedia/games applications like TuxType, TuxMath, Gcompris, Supertux 
already running. If he counts more than 2 of them he pops up a message 
box, which gives an option to kill the already running ones.
This script is only working for the  programs, if you edit their  
*.desktop files found in the folder /usr/share/applications.
Every of this programs will start then indirectly by start-prog.


Example based on Tuxmath:

1.) copy the start-prog file to /usr/bin

2.) give execute permission to this file
chmod 755 /usr/bin/start-prog

3.) Than edit file tuxmath.desktop file in the  folder 
/usr/share/applications

4.) Change the Exec line to
Exec=/usr/bin/start-prog  tuxmath --window

5.) edit the start-prog file and add the program to the array 
CRTITICAL_APPS.

6.) Do steps 3-5 for all critical program which should be monitored.

Note: The dialog boxes needs the program/package gtkdialog !

I think after you have implemented this together with gnome-watchdog. 
There is no need anymore to tell the students to close some programs.

Good luck!

Philipp
