Google. "man $PROGRAM". /usr/share/doc/howto/ if you have the
HOWTO packages installed. http://tldp.org/docs.html#howto .
If dead trees are your thing, the latest edition of the
O'Reilly book _Running Linux_ may help--but it's a bit basic.

Next time I go by Borders, I'll take a look at it. I did do
some looking around and tracked some stuff down. Another
responder was correct, the daemon doesn't start if you login
as root, I should say, it no longer starts. It used to 6 or
7 years when I was running Redhat something or other on some
antique PC's (386's & 486's).

quesion about playing movies and I realize that question
and this may be related... if the movie player couldn't
access the screen, it wouldn't work.

Too specific. If an X app can't access $DISPLAY, that X app
won't work. But if you logged on to X as USER, and you
started gmplayer as USER, gmplayer should have full access to
:0 and should just work. I think you've omitted important
information. Try this: Log in to X as a normal user, open an
{xterm,konsole,aterm}, enter "gmplayer /path/to/something.avi".
Reproduce the error messages you receive. If you don't have
gmplayer installed, use ogle or xine or whatever.

That worked, I used totem to watch an avi file. In awhile, I'll
fool around trying to download and install A some other CODEC's.

BTW, I was able to watch abut 5 seconds worth of a video
clip from some website (youtube?) before it died.

The evil binary-only Flash plugin has its own problems. I
don't know which version was standard with FC4, but it's
almost certainly outdated by now. Update.

FC4 didn't have Flash installed, I installed it after d/l'ing
it.

I get the error message: "The XScreenSaver daemon doesn't
seem to be running on display ":0.0". Launch it now?" with
Cancel and OK buttons. If I click OK, I get a much longer
explanation about not being [able] to start the xscreensaver
daemon.

And what is the text of this message? Go read
http://catb.org/~esr/faqs/smart-questions.html for an
explanation of what is most likely to work well for getting
tech support in text-only media.

From memory, it was an admonition to not run as root unless
you had to and use su and sudo as needed. I rarely login as
root except to use "yum update".


Macs are not cheap, even if you go to smalldog.com . Who's
paying for this? WP is essentially dead outside of legal
firms. OpenOffice is Free even though it's a ~110M download,
and it reads (probably doesn't write) WP files.

As things turn out, she is a lawyer in a one person law office.
She hires the husband of a friend of hers come over and update
her virus scanner at her office and sometimes at her house.
I'm to far away and work in the opposite direction from her to
be much help quickly. I don't think her Win98 system is going
to be easy to salvage without reformating the hard drive. I
don't see any easy solution without some level of heartache and
pain.

What I would like to do is hook my laptop (running FC4) to
her PC and capture the packets. I want to see how much is
on her PC that is trying to connect to the net. [massive snip]

Read and understand the IP-Masqing HOWTO, though you'll probably
need 2 NICs in your laptop for everything to work right. Capture
the packets with ethereal (wireshark), look at them. Remember,
brevity is the soul of effective communication on Usenet.

I d/l'ed and tried to install Wireshark but ran into issues
with ./configure - it actually isn't worth pursuing right now.
I was looking to quantify how much stuff was trying to get to
her internet connection instead of "a lot of light blinking on
the modem".

How do I start chipping away at my mountains of ignorance?

Read The Fine Manual, Search The Fine Web.
http://groups.google.com/advanced_group_search is also useful.
The following procedure also works:

0. Try something you haven't tried before.
1. If it worked, remember it, use it again. If not, remember
how it failed, don't do it that way again.
2. Goto 0.

There so much to try and keep track of (wait, last time I
tried that, did it work or didn't it...)
I prefer dead trees for general concepts and principles,
those are much more accessible while in the throne room<g>.
