On this episode I show you how to comment out configuration files. This is fantastic for writing yourself notes of what you may have did and why. Not only is it great for notes, it is one of the easiest ways to turn “off” a setting or command in the text file with out deleting the whole line of code! That way in the future you can quickly turn that line “on” by simply removing the comment.

Every programming langue has its own way of dealing with comments. In Linux, by far the most common way to comment files is with the # symbol.

This is true for most configuration files and true for bash scripts. Simply put a # symbol in front of the line you want to turn “off” and it is as simple as that. For lua type configuration files (if you happen to be using the awesome windows manager) the comment symbol is —

It is also a good idea to write yourself a note to a line you may have commented or uncommented out. That way you can remember if you ever need to edit the configuration file again why you did what you did. Notes are super helpful and friendly.

I also quickly show off nano, a text based editor for the terminal. Although I don’t use it that often, it is great to know the very basics! If you fail to get a graphical user interface started but are able to get to a terminal and or shell, nano is an excellent tool to edit text/configuration files in hopes to fix up your system should you have edited something you weren’t suppose to edit (yes I have been there).

On this episode I show off the copy command, cp in the terminal and the move command, mv in the terminal. This is an excellent way to backup configuration files before you modify them. If things do go south, like it has for me in the past, then it is pretty easy to restore via a terminal. If the worst does happen, and you can’t get into your graphical user interface, then this is an excellent way to restore configuration files. Had I known this when I frist started using Linux, it would have saved me a few hours worth of work.

My suggestion is practice this a few times with a mock folder and some mock files. Practice using the cp and mv commands until you feel comfortable. That way in the future, if you need to restore a file, you will feel okay doing this with just a terminal.

In this episode I go over a lot of stuff about package managers and how they work. Here is a link with some great basic information. http://en.wikipedia.org/wiki/Package_management_system

Towards the end of the video I explain PPAs, more info on PPAs can be found here. http://www.makeuseof.com/tag/ubuntu-ppa-technology-explained/

I quickly show you how to install a system monitor tool that runs in your unity bar. Info on the PPA program can be found here. http://www.noobslab.com/2012/02/install-indicator-multiload-in-ubuntu.html

If you want to simply paste the code in your terminal, the code to install this software is this…

  • sudo add-apt-repository ppa:indicator-multiload/stable-daily
  • sudo apt-get update
  • sudo apt-get install indicator-multiload

Warning! You should understand PPAs before installing on your machine. You should understand the pros and cons to installing PPAs. ANYTIME you see sudo you should always understand the commands following it. After all, you are giving that command administrative access.

On this episode I show of a Unity desktop environment bug that is greatly reducing my work flow. I still really like Unity but this bug has me down.environment. Perhaps in the future this bug will be fixed or I will learn to live with it.  For now it is back to the awesome windows manager and xfce desktop.

The Unity desktop environment and this bug as made me think a lot about workflow and how I want my Linux setup to function. I see many videos on desktop environments but few people explain HOW they got there and some of the pros and cons to such a setup. Sadly I haven’t found a lot of videos on workflow and the Linux desktop. Which is a real shame as this is one of the huge pros to Linux, you can really teak some desktop environment to really meet your needs and goals. It is my goal so give you some ideas and show off some tweak-able settings to you can start thinking about YOUR work flow and really take advantage of what Linux has to offer.

Most of the tweaks I show you are in xfce4. Some of these tweaks can also be done in lxde and kde desktop environment. The idea is to get you thinking about how you may want to change some of your settings.

I also show you how to reset your xfce4 settings if you mess things up. Please keep in mind…

This will delete out ALL xfce4 settings, including keyboard shortcuts. All data will be safe, just all xfce4 settings will be reset to default. If you want to reset JUST the panel, navigate to this folder…

~/.config/xfce4/xfconf/xfce-perchannel-xml

Then delete out the file xfce4-panel.xml

This will reset the panels ONLY and will leave all other settings intact.

On this episode, I go over some commonly used applications in Ubuntu 12.04. I show you where you can get more applications and I quickly explain what they do. If you are looking for a quick book to read check out http://www.amazon.com/Ubuntu-Made-Easy-Project-Based-Introduction/dp/1593274254/ref=sr_1_1?ie=UTF8&qid=1352058988&sr=8-1&keywords=ubuntu+based+project

Keep in mind, I don’t get any money for this recommendation, nor do I know the author in anyway, shape, or form. I simply thought it was a decent read for new users. It goes over how to install Ubuntu, basic trouble shooting, some applications, and where to find more help. If you are running Ubuntu 12.04 and you are looking for a book, this is a decent read. Not a must have, most information can be found online, but it is decent for new users.

If you are not running Ubuntu 12.04 then I don’t recommend this book. If you are an advanced user I don’t recommend this book. If you already have Ubuntu installed, you will not need to read the first few chapters.

We finally get to the video of how to set up a dual boot system! Before you being, make sure you have gone though these steps…

1.) Pick a distribution

2.) Make sure you tested that distribution, if applicable, via a live CD or USB stick. Test all your hardware before installing!

3.) Make sure you know where you want to place your master boot record file for Linux, either the default set up, or and advanced setup.

4.) Back up all of your data!

5.) If you don’t want to use the default distribution’s partitioner, partition out your hard drives before hand.

6.) If you do want to use the defualt distribution’s partitioner, make sure you have an idea how you want to set up your hard drives for when the time comes.

7.) Back up all of your data!

8.) Use your CD or USB stick to begin the installation!
