How to set an environment variable

I have FC-5 and use KDE.

How do you set an environment variable? Specifically the DISPLAY or $DISPLAY variable, (does the $ mean anything?). Also, I don't know anything about daemons. If I had an error message that said the "xscreensaver" daemon wasn't running, how would I launch it? Right now I just have the command "xscreensaver" on a line in rc.local.

Thanks,

rc.local is commonly run before a switch to the final run-level,
so xscreensaver won't be running for you because it can't connect
to X. But with KDE you should be able to run it from ~/.kde/Autostart ?

As for the variables:

export VARIABLENAME

It is then later on referenced with $VARIABLENAME, e.g. echo $DISPLAY.
