I have a couple of questions for Linux admins/gurus.
I volunteer at a computer hub in Wellington and would like to know how to do a couple of tasks. First off, he hub uses Debian 6, and second, I do not have many privileges apart from being able to administer users (but I will be presenting any info to the technician for consideration), third, I can view all the users logged on with $ w
The first task is to find out what would be the best way to display a pop up message on all the users screens who are logged in. I have looked at a couple of options ($ wall and $ xmessage). wall only shows if the user is in a terminal and most of the users are in the X and I couldn't work out how to use xmessage to send to other logged in users. I have also considered adding a task to chrontab which would display a message 10 minutes before closing but I think if it is possible to send a message to all or a single user, it would be more suited to the project.
The second task is, is it possible to change the power saving settings for the login screen? Would it be possible to disable the monitor power saving settings and show a screensaver instead. Is there a configuration file I would have to change and what would need to be added to the conf file to change the power saving settings.
If you need any more specifics I will try to answer as best I can.

I'm not exactly sure what you are looking for here - is the default desktop environment using Gnome?

The configuration is under: System -> Preferences -> Screensaver
The config appears to get saved to:

$HOME/.gconf/apps/gnome-power-manager/
$HOME/.gconf/apps/gnome-screensaver/
