Desktop sessions dying with time

[Michael Jinks <mjinks@uchicago.edu>]

Hi all.

I just set some users up with a new Woody desktop, and they're claiming
that if a session is idle for too long, it gets logged out.  They mostly
use GNOME with Sawfish.

This isn't a behavior I've seen before; my own desktop is Woody, and
certainly runs for many days at a time without making me log back in.
So I figure that either something is crashing and killing their desktop
session, or else I somehow inadvertently enabled an idle-timeout feature
in X or GNOME.

Is there such a feature somewhere?  I haven't been able to find anything
but I've only looked through the user-level config tools (GNOME control
panel, sawfish-ui), and nothing in my knowledge of XFree86 configuration
touches on this sort of thing.

I've known xscreensaver to crash a desktop session from time to time,
but it wasn't installed.

So I'm hunting for hints.

Thanks,
