Of interest to me was trac-bzr. Since Bazzar has the power of Canonical behind it, a cursory glance at the “universe” repository shows a package named “trac-bzr”. However a closer look reveals that this package is quite outdated:

>apt-cache show trac-bzr
Package: trac-bzr
Priority: optional
Section: universe/python
Installed-Size: 156
Maintainer: Ubuntu MOTU Developers <ubuntu-motu@lists.ubuntu.com>
Original-Maintainer: Chris Lamb <chris@chris-lamb.co.uk>
Architecture: all
Version: 0.2+bzr31-3
...

This seemed like a bad idea, seeing as the main branch was already at r69.

Here are the instructions on installing the latest version:

1. Make sure you have bzr installed

sudo apt-get install bzr

2. Get the latest version of trac

sudo apt-get install trac

3. Get the latest version of trac-bzr, and put it in a revisioned directory.

bzr export ./trac-bzr-r`bzr revno lp:trac-bzr` lp:trac-bzr

4. Install the plugin

cd trac-bzr-r*
python setup.py install

5. Configure trac to use the plugin as described in the trac-bzr README

If I had kmixer open, I could see that the keys were manipulating the PCM channel, not the Master or Front channels. A Google search later turned up a ticket on Launchpad. Turns out all you need to do is right click on the volume icon in the system tray and select “Select Master Channel…”.

For me, “PCM” was selected. I changed it to “Master” and viola

The problem originates somewhere between XGL and using your numeric keypad to control the pointer (known as Mouse Keys).

If you’re sure you don’t need XGL (check your xorg.conf first!), then simply remove it:

sudo apt-get remove xserver-xgl

And disable your Mouse Keys:

1. System -> Preferences -> Keyboard
2. Mouse Keys (tab)
3. Uncheck “Allow to control the pointer using the keyboard”

Now restart your machine, and Voilà

Say you want to run Azureus with Java 6 but you don’t want to install the JRE from Ubuntu repositories.

1. Download the JRE binaries from http://java.sun.com ( or whatever JRE you want )
2. Download an application that requires a JRE
3. Run the following in your terminal:
   (PATH=/path/to/your/java/executable:$PATH && \ /path/to/the/app/to/run)
4. Make sure to wrap you command in parentheses!

What’s happening here is:

1. You are prepending the location of the new JRE to your current PATH variable
2. If that was successful, you are executing your application. If not, then your application won’t be started
3. All of this is done within a set of parentheses. This runs everything in a subshell. When you exit the application, your regular PATH variable is untouched.

However, for the 0.5% of the time where you cannot use keys, you can use a little program called expect.

BTW, this does not, and should NEVER work:
echo 'mypassword' | ssh user@server

Installing Expect:
sudo apt-get install expect

Create the expect script:
nano connect.sh

Paste the basic code:

#!/usr/bin/expect
set timeout 60
spawn ssh -l username server
expect "password: $"
send "password\n"
expect "$ $"
interact


Replace ‘username’ and ’server’ on line 3 and ‘password’ on line 5.
The second to last line, ‘expect “$ $”‘ is for a bash shell. Replace the first ‘$’ with whatever your prompt is.

Save ( ctrl + o ) and Exit ( ctrl + x )
Make the script executable
chmod +x connect.sh

After some searching on Ubuntu’s launchpad, I found the answer:

Open /etc/default/acpi-support

sudo nano /etc/default/acpi-support


Add networking to the STOP_SERVICES. For me it was on line 61.

Before

# Add services to this list to stop them before suspend and restart them in
# the resume process.
STOP_SERVICES="mysql"


After

# Add services to this list to stop them before suspend and restart them in
# the resume process.
STOP_SERVICES="mysql networking"


Your wireless should now come back after Suspend / Hibernate.
