Ubuntu (Edgy) Starter Guide

http://ubuntuguide.org/wiki/Ubuntu_Edgy

Adding startup service

To ensure a service which exists in /etc/init.d is run on startup, simply run:

sudo update-rc.d <service> defaults

Enabling Printing

1. /bin/chmod 06555 /usr/bin/lpr /usr/bin/lprm
2. /sbin/chkconfig lpd on

Hardware

Logitech MX-1000

Add this section to your /etc/X11/xorg.conf:

Section "InputDevice"
        Identifier      "Logitech MX-1000"
        Driver          "evdev"
        Option          "CorePointer"
        Option          "Name"        "PS2++ Logitech MX Mouse"
        Option          "Buttons"         "20"
        Option          "ZAxisMapping"    "4 5"
EndSection

where "Name" is read from the relevant "Name" for your device in /proc/bus/input/devices. Then follow the remaining instructions in http://www.ubuntuforums.org/showthread.php?t=65471

Although this document describes the steps for a USB mouse, this also works when connected to the PS2 port. Note, however, that a Logitech MX-1000 forward and back keys are 8 and 9, and xvkbd is located in /usr/bin rather than /usr/X11R6/bin. In addition, as stated in the text, part 1.4 is unnecessary.

In newer versions of X11, it seems that evdev is a driver rather than a protocol, so you'll need the line:

Driver     "evdev"

rather than

Driver     "mouse"
Protocol   "evdev"

Also, I needed to append "SendCoreEvents" to the Logitech line in the layout section

Convert m4a to mp3

ffmpeg -ab <bitrate in kb/s> -i <inputfile> <outputfile>

Note: the error output buffer too small can be ignored.

Changing default ALSA soundcard

asoundconf list
asoundconf set-default-card <cardname>

List hardware details

sudo lshw -businfo

Add swap space

• Create swap partition using fdisk

• Create swap filesystem

sudo mkswap <device>

• Activate swap

sudo swapon <device>

• Modify /etc/fstab to allow swap to be activated at boot time
