Re: sleepy monitor??

All *nix systems have six run levels.  Red Hat uses:
    0    Shut down all services and halt.
    1    Single-user mode.  Only the console is
         enabled.  The console user is
         automatically logged in as root.  No other
         connections are permitted.
    2    Multi-user without networking. Rarely used.
    3    Standard multi-user text mode operation.
    4    Not used.
    5    Standard multi-user operation with
        graphical login.
    6    Shut down all services and reboot.
Note:  Different Linux Distros switch run levels 3, 4, & 5 around.

Run levels 2 and 3 vary by distro in their interpretation.

I'm not positive, but I think that RH based distros might consider 3 to be
undefined (as is 4). What is considered as multi-user on RH is 2, while on
debian it's 3. Or something like that.

Can someone please explain in an understandable way what's what on which?

I would have thought so too. They were not set to run on runlevel 3.

    httpd/mysqld/smb should all run whether runlevel 3 or 5

    You aren't likely to see that much of a difference between the two
    runlevels until someone logs in - at which point, on runlevel 5, a whole
    lot more processes are started.

    until then, the major difference between the two will be found

    ps aux|grep gdm

    just to be sure though, I confirm...

    chkconfig --list [service]

    chkconfig --levels 2345 httpd on
    chkconfig --levels 2345 mysqld on
    chkconfig --levels 2345 smb on
