Ubuntu Multi Media How To

I've found a comprehensive multi media guide for Ubuntu at ubuntuforums.org

The guide works for 8.04 and prior and gets you set up with the best multi media apps, codecs, etc

Check it out:

Trial Run of Ubuntu 8.04 Hardy Heron

Over the past few weeks I've been running Fedora 9 on my laptop, in my experience, F9 does not perform well on my system. I haven't tried it on any of my desktop hardware, so I can't pass judgment past using it on the Dell XPS m1330. Maybe there are too many brand new technologies in this release?

I was about to roll back to Fedora 8, which performed well on the hardware, when I thought, why not give Ubuntu Hardy Heron a try.

In the Linux realm, I have always chosen Red Hat or other RPM based distributions over the others. So this is slightly unfamiliar territory for me, being Debian based.

Power Savings
Since this is a laptop, I wanted to get max performance when on AC power and max battery when off of AC power. I did so by following these steps.

I also modified /etc/X11/xorg.conf from

Section "Device"
Identifier "Configured Video Device"
Driver "nvidia"
Option "NoLogo" "True"
EndSection

to

Section "Device"
Identifier "Configured Video Device"
Driver "nvidia"
Option "NoLogo" "True"
Option "OnDemandVBlankInterrupts" "True"
EndSection


And added a new script to Sessions (System -> Preferences -> Sessions) called "Nvidia Power Settings" with the following code:

#!/bin/bash
while true; do
if on_ac_power; then
nice /usr/bin/nvidia-settings -q all > /dev/null
fi
sleep 25;
done


The following are the steps I took to get Ubuntu to play an off the shelf copy of Pink Floyd the Wall DVD (which would not play with the default install of Ubuntu 8.04). The DVD is apparently of the encrypted variety.

Firewall
I ran into an issue with the default policy for the Firestarter firewall where it wouldn't allow traffic on my VPN connection. Using this page as a reference I was able to get VPN traffic to pass through the firewall. Here are the settings that I used in /etc/firestarter/user-pre:

iptables -A INPUT -j ACCEPT -s IP_OF_VPN_GATEWAY -p esp
iptables -A INPUT -j ACCEPT -s IP_OF_VPN_GATEWAY -p udp -m multiport -sports isakmp,10000
iptables -A INPUT -i tun0 -j ACCEPT
iptables -A OUTPUT -o tun0 -j ACCEPT
