I have been using lucid ubuntu 64 bit on this pc for months with no problem till yesterday. I noticed yesterday that eth0 was no longer being set up on boot and so internet is not there now. I am currently on the internet using karmic ubuntu.

Any ideas why this happened...I'm thinking an update with aptitude? What can I do in lucid to get my networking working? I tried booting into recovery mode and repairing packages but my pc could not get on the net to check the packages.

Rightclick the network manager icon on top right of the panel and see that enable networking is ticked.
Hope it is enabled in BIOS

I am not sure about xubuntu.Can you post the results of
gksudo gedit /etc/NetworkManager/nm-system-settings.confand
gksudo gedit /var/lib/NetworkManager/NetworkManager.state

I don't have NetworkManager binaries (I did a locate NetworkManager and nothing was in /bin /sbin /usr/bin or /usr/sbin) and nothing called NetworkManager was available to add to my panel.

Here's nm-syste-settings.conf

# This file is installed into /etc/NetworkManager, and is loaded by
# NetworkManager by default. To override, specify: '--config file'
# during NM startup. This can be done by appending to DAEMON_OPTS in
# the file:
#
# /etc/default/NetworkManager
#

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

******************************************

Here's NetworkManager.state


[main]
NetworkingEnabled=false
WirelessEnabled=true
WWANEnabled=true


**********************************************

Here's what's been bothering me since I'm the only user on this pc...WHO did this?!?!?! Was my pc broken into by somebody on the net who disabled my networking?

nothing called NetworkManager was available to add to my panel.You need to add notification area as follows
1)Right click on the top panel-click add to panel-select notification area -click add (pl see attachment)
2)run
gksudo gedit /etc/NetworkManager/nm-system-settings.confand set
managed=true
3)run
gksudo gedit /var/lib/NetworkManager/NetworkManager.state
and set
NetworkingEnabled=trueRestart and see if it works

woohoo!! That did it-I think you were right too about updates causing this. Weird-I'm working inside XUbuntu x86_64, so why is aptitude grabbing Ubuntu packages that could mess up my system?
