Ubuntu & Linux Software
by Brian K. Lewis, Ph.D.*, Sarasota Personal Computer Users Group, Inc.
I suppose some of you might be wondering why I have been writing about the Ubuntu Linux operating system and Linux software. As I noted in last month's article my laptop is now my sole computer. Although it has a Pentium 4 processor it only has 512 MB of RAM. Naturally, that means it is incapable of running Windows Vista. But it does easily run Ubuntu with more than enough memory to do multi-tasking with no reduction in speed. I also know that there are a number of the members of the SPCUG that use computers that are running Windows 98 or Windows XP. The point is, that it is not necessary to try to upgrade these computers to run Vista or to buy a new computer. Instead you have the free alternative of installing Ubuntu or another version of Linux. This article will discuss some of the range of free Linux software and how easy it is to install it.    The original installation CD of Ubuntu included the OpenOffice software. OpenOffice includes a word processor, spreadsheet and presentation applications. These are fully compatible with the components of Microsoft Office. I frequently receive documents prepared in MS Word and they open directly into OpenOffice Writer. I can edit, comment and save a copy in the OpenOffice format. Then I can return the modified document to the originator in MS Word format with all the edits and comments intact. The same is true for spreadsheets. The OpenOffice presentationapplication (Impress) reads, writes and modifies PowerPoint files as easily as Writer works with documents. OpenOffice also includes a Drawing application. Drawing is an application that I haven't used.    Other included software with Ubuntu are Ekiga (internet phone software), Pidgeon (internet messenger), Evolution (e-mail), and a remote desktop viewer. Graphics software includes the F-Spot photo manager, GIMP Image Editor and Xsane scanner software. Also, there is a CD burner, movie player for DVDs and two music players.    I grant you that the included software doesn't always meet all the needs for many users. So Ubuntu has several ways of installing additional software. I mentioned last month about installing the drivers for my printer, scanner and the wireless modem. This month I will continue with other applications that are the equivalent of those that I used under Windows. The installation of these applications was much easier than installing drivers for the accessory hardware.    The first step in installing any application is to go to the Applications - Add/Remove menu. When this application runs it provides you with a list of all the software available through Ubuntu and its third-party providers. On the left side of the window are listed various categories that you can highlight and the appropriate applications are then listed on the right side. When you highlight a specific application, a description appears in the lower portion of the window. There is also a search box that you can use to find a specific program or a group of programs.    Since I maintain my financial records on my computer I wanted a financial program that ran under Ubuntu. Not knowing the specific name, I just searched on the term "finances". This brought up a list of financial software. One of the interesting aspects of the Add/Remove application is that programs are rated based on feedback from users using 1 to 5 stars. There was a 5 star application listed, GNUcash, which can import files in the Quicken format. So I put a check mark in the box by the application name and then clicked on the "Apply Changes" button. This brought up another window for verification of the changes to be made. After clicking on "OK", the application was downloaded from the Internet and installed on the hard drive without any further action on my part. A shortcut icon was also added to the Office portion of the applications menu. There was no reboot required to complete this process. After the installation, the "Add/Remove" application reported the successful installation and remained open in case I wanted to use it further.    My Windows financial software was Microsoft Money. Supposedly it will export its data files in the Quicken format. I did that and then copied the files from the Windows partition to the Ubuntu partition. However, the import into GNUcash was not really successful. I'm not sure why but I suspect there was information missing which resulted in misidentification of some of the accounts. Anyway, I selected an arbitrary date and entered opening balances for that date. So now, it is working perfectly and is in agreement with my bank balances. Using it is even somewhat easier than working with either Money or Quicken. Plus, the price is right.    Another application that I needed for Ubuntu was a genealogy program. Here again I was able to find a five star program, GRAMPS. (Very appropriate name I thought.) It was also available through the "Add/Remove" application so installation was completed quickly. GRAMPS imports GED files as do many genealogy programs. So I exported my files from my Windows software in the GED format then copied the GED file to the Ubuntu partition. The import into GRAMPS was	essentially a two-click operation. Everything, including notes and references, were now available in an Ubuntu application. GRAMPS also has more report formats than my Windows software included. So I consider it a very successful replacement.    For quite some time I have used a PDA, specifically a Sony Clie which runs Palm Pilot software. The Sony CD loaded the Windows version to the hard drive and also included software to synchronize with the PDA. Since I have considerable contact information in the Clie along with many memoranda, I really wanted to be able to run this under Ubuntu. In the System-Preferences menu there is a selection for PalmOS devices. Now that sounded like it would be quite simple to install the applications necessary to run the Clie. Clicking on the selection runs the Gnome-Pilot application which helps the user to determine the settings for synchronizing with the Clie. Unfortunately, it could not find the Clie PDA. So I had to go back online to the Ubuntu forums to see if I could find the secret. It turns out that getting a PDA recognized and synced with Ubuntu is not always simple. After spending considerable time reading various solutions I came across a command line entry that showed the entries where my Clie was being recognized by Ubuntu. The PDA was properly identified by vendor and product ID's. Now all the information I had gathered indicated that the PDA should be listed as using a USB connection and usually ttyUSB0 and ttyUSB1. Much to my surprise my printout showed the Clie as using ttyUSB9 and ttyUSB10. The Gnome-Pilot software refused to accept either of these as valid locations. However, another application, J-Pilot, accepted ttyUSB10 and synced with the Clie when the sync button was clicked. The synchronization transferred all of my information directly into the J-Pilot software. This software works on the desktop in a very similar manner to the Clie and Pilot software I had used under Windows. Successive synchronizations have also been successful. So that was one less application that would need to run under Windows.    There has been one big disappointment in the hardware setup. I have a multi-function media card reader built into the laptop. It reads SD cards as well as xD, MMC, and memory sticks. This reader works great under Windows as a way to transfer photos from my camera to the computer. However, there is apparently no driver available for this to work under Ubuntu. The card reader is manufactured by 02 Micro and they apparently don't believe Linux is here to stay so they have no plans to create Linux drivers for any of their products. At least that's the quotation from a response to a query from a Ubuntu user. So when I have photos to transfer to my computer I can either reboot into Windows, or I can connect the camera with a USB cable. The USB cable works fine as Ubuntu recognizes the camera right away. It also opens the F-Spot Photo Manager which allows me to choose the pictures and the location where I want them saved.    One of the applications included with Ubuntu is Brasero, a CD/DVD burner. When I first tried to use it, it refused to recognize my DVD+R discs. It would read and write DVD-R/RW with no difficulty. Since I had a supply of the +R discs I decided to look for other DVD burning software. In the ADD/Remove application there were several CD/DVD burners listed. One of them was five star application called K3B. It was written primarily to work with the KDE destop that is an alternative to the GNOME desktop. The KDE desktop comes with Kubuntu and has an interface that is closer to the one found in Windows. Anyway, K3B will work with GNOME, so let ADD/Remove install it. Any software that you add through Add/Remove can be removed simply by locating it in the list and removing the checkmark that indicates it has been installed. So now I have both Brasero and K3B installed. I also found, the next time I wanted to burn a DVD, that Brasero would now work with my external burner and the +R discs. I do like the interface for K3B better than Brasero, but they both work.    As you can see one of the nice attributes of using open license software is the ability to install it and use it at no cost. If you don't like it, you simply remove it. It's certainly not that simple in Windows. So, if you want to try a Linux OS on your computer download a "Live CD" and try it out. Also check out the online help forums. I think you'll find them easier to understand than much of the material Microsoft makes available. Whatever you decide, enjoy your computing!    *Dr. Lewis is a former university and medical school professor of physiology.
