There are several 'standard' cron jobs that Linux (generally UNIX) run:

1) Daily (usually about 4AM) there are two main ones: updating the slocate database and rebuilding the whatis database

2) Weekly (generally early Sunday AM): log rotation.

The runlevels from 2-5 (or 3-5) are the full multi-user. There are several to allow for several different options: with networking, without networking, with X11 login, without X11 login. With a SysV startup, it is possible to create several sets of startup script sets, which can be selected by the selected runlevel.

Yes, this can be confusing at a certain level. The 'XServer' is the process that is directly attached to the hardware (video card, keyboard, pointing device mouse) and provides the graphics services to one or more *Clients*, which are applications that interface to the user in a graphical manner (via a 'GUI). The XServer and the Clients need not be running on the same machine, since the XServer and Clients are fully networked programs. The XServer process always runs on the hardware the user has physical contact with -- the keyboard and mouse that the user is touching with his-her hands and the screen he-she is looking at. It is possible to run more than one XServer process on the same machine, either with multiple video cards-keyboards-mice OR with multiple incarnations using the same hardware and separate *virtual* terminals, or to run an XServer as a client process in a window of a parent XServer (XNest). In the latter case, the nested XServer can be on a different physical machine that the one it is nested in (since it is also a client).

slocate expects updatedb to run each day (usually at 4AM), when this does not happen, slocate detects that the satabase file is 'old' and warns you that the information it is giving you is probably out of date. Or possibly, it is deciding that since the database is old, it is not going to use it all. You should run updatedb again.
