For some reason, if I leave my desktop unattended for 20 – 30 minutes, and even if something like Amarok is playing, when I come back I find myself looking at the KDM login screen, which means that I’ve been automatically logged out. When I grepped /var/log/daemon.log for kdm, I got the following readout:

Now, I'm sure there could be several possible reasons for this peculiar behaviour, but my question is, where would be a good place to start looking for the cause (e.g. any specific log or configuration files)?
Thanks.
