OK, this is unrelated to MythTV, but I hope that you do have a battery backup for those times that the power company fails you, as well as to provide steady power to your box. The software enables your machine to go through clean shutdown when the power is off for a configurable amount of time. I have an APC Back-UPS ES 500 (usb connected), so I will go through what it takes to install the APC management software, specifically for this model. Your installation should be the same, as long as your UPS is USB connected. If not, please refer to the References section below, and go to the apcupsd website for documentation.Before you even get started, try

cat /proc/bus/usb/devices

If you can’t find your APC device within the list output by this command, stop and connect it (remember, USB). If it is still not there — sorry, I can’t help you! Once you are confident that the APC device is recognized, install the software:

apt-get install apcupsd

Now, edit the apc configuration file at /etc/apcupsd/apcupsd.conf. Scan through this file, making sure that the these particular settings are like this:

UPSCABLE usb
UPSTYPE usb
DEVICE

(yes, make sure that DEVICE is set to nothing). Now edit /etc/default/apcupsd, and set ISCONFIGURED to yes. Start the apcupsd daemon:

/etc/init.d/apcupsd start

Now type

apcaccess status

and if you get a batch of output telling you information about your UPS, you’re done! At this point, you can either stop, or go to the Apcupsd daemon for controlling APC UPSes site (click on documentation) to further fine tune the behavior of your battery backup. I found the defaults fine for me, so I stopped here.

When you boot your machine, it would be nice if it would go straight to MythTV; however, at this point, it boots to the graphical login screen. This is easy to fix; just edit /etc/gdm/gdm.conf, change the AutomaticLoginEnable and AutomaticLogin variables to:

AutomaticLoginEnable=true
AutomaticLogin=mythtv

Or Setup the timed login

***nfs server
sudo apt-get install nfs-kernel-server nfs-common portmap
When configuring portmap do =not= bind loopback. If you do you can either edit /etc/default/portmap by hand or run:
sudo dpkg-reconfigure portmap
sudo /etc/init.d/portmap restart
Editing /etc/exports
the /etc/exports file is used for creating a share on the NFS server
invoke your favorite text editor or
sudo vi /etc/exports
Here are some quick examples of what you could add to your /etc/exports
For Full Read Write Permissions allowing any computer from 192.168.1.1 through 192.168.1.255
/share 192.168.1.1/24(rw,no_root_squash,async)
sudo /etc/init.d/nfs-kernel-server restart
Also after making changes to /etc/exports in a terminal you must type
sudo exportfs -a
sudo /etc/init.d/portmap restart
sudo /etc/init.d/nfs-common restart

***nfs client
sudo apt-get install portmap nfs-common
sudo mkdir /share
sudo gedit /etc/fstab
add:

Save the file
sudo mount -a
The directories should be available immediately and after reboot.

This is a cool process to go through if you are testing ubuntu on a system and have to re-install a bunch of times. Found it at http://www.arsgeek.com/?p=564

dpkg –get-selections | grep -v deinstall > ubuntu-files

So now you’ve got this list and all is well, until you’re Ubuntu install either dies or has to be reinstalled for some reason. Go ahead and do the base install.Once you’ve got Ubuntu back up and running, copy your ubuntu-files back into your home directory and do the following:

sudo apt-get update

sudo apt-get upgrade

dpkg –set-selections < ubuntu-files

Now you’ve told your system what it needs to install, so let’s install it all.

sudo dselect

This will open up a dselect session. Type ‘I‘ and allow dselect to install of the the packages listed in your ubuntu-files document. When it’s finished, type ‘Q‘ and hit the ENTER key to exit dselect.

***ivtv stuff
If you get an error saying that modprobe cannot find the ivtv module, then try:
cp /lib/modules/2.6.15/ivtv/* /lib/modules/2.6.15-26-386/kernel/drivers/media/video/
of course, replace 2.6.15 and 2.6.15-26-386 with the appropriate numbers for your system.
