Linux Migration Guide: Installation Tips
linux Migration Guide: Installation Tips
While all Linux distributions are different, they ultimately all go through a similar install process. Rather than walking you through this process step-by-step like you could find in the distribution's documentation, this page addresses the issues you're most likely to encounter and recommendations for solving them.
There will be many cases where the distribution installer offers to make decisions for you. If you aren't sure, go with its recommendations. More often than not, the default options are fine.
Multi-Booting
For a lot of people, there might be one Windows program (or game) they just can't do without. Others would just like the security blanket of knowing they can return to their Windows installation if they need to. In these cases, by far the best option is to leave Windows running on one computer and install Linux on another. However, most people aren't made of money and don't have spare computers just lying around.
If you can't manage a second computer, then the next best scenario is adding a second hard drive to your existing computer. Doing so allows you to dual boot, which means that you can install Linux on the other drive and have a menu that comes up when you start the computer, asking whether you want to use Linux or Windows. Don't worry though if you don't have the room or funds for an additional hard drive. You still have one more option.
The third option is to resize how much room Windows gets on your hard drive, and install Linux in the space you've freed up.
Those who go with the first option can install on their new Linux box with impunity. Choosing option two means you just need to add the second hard drive, make sure you know which drive the second drive is, and then install. The installer will let you choose the hard drive to put Linux on. Just in case, back up your important data first, whether you're going with option two or three.
Speaking of option three, if you're going with this choice, you have some reading to do. It's best not to just jump in and start, make sure you understand what you're getting into first! Really it's not all that hard. However, you don't want to have to go back and reinstall Windows afterwards. That's just an assumption.
The process for setting up dual booting is very similar across distributions, so a resource for one works pretty well as a resource for most until you get into the distribution's installation instructions.
Some excellent materials that will help you prepare your system are:
- How to dual boot Linux and Windows
- A video on how to set up dual booting
- Creating a Dual-Boot Windows XP and Ubuntu Laptop
- The Windows Dual Boot HOWTO from Ubuntu.
GNOME or KDE?
As discussed in Choosing a Linux Distribution to Replace Your Windows Desktop, GNOME and KDE are the two major choices for your Linux GUI. Some people swear by one or the other, but really, it's a personal choice as to which you prefer. Often you have the option of installing both of these desktops. If you have the space, installing both lets you experiment and decide for yourself.
Another option is to try both GNOME and KDE in a bootable distribution before you install. Out of Fedora, Kubuntu, Mandriva, openSUSE, and Ubuntu, only Kubuntu doesn't come with GNOME, and Ubuntu doesn't come with KDE. The others come with both unless you download a GNOME- or KDE-only version.
Updating as Part of the Installation
No operating system or program is 100% secure. Even if it manages to be for five minutes, the next minute someone may find a vulnerability that they can exploit. It's imperative that you keep everything up to date, so start this good habit by allowing the installer update your newly-installed system unless you don't currently have Internet access. The cool thing is that by updating, you'll have all of the latest versions of any other software as well.Getting the Apps You Want
Not every distribution installs the equivalents of popular Windows applications, such as Flash or Adobe Acrobat. Here's how to find and install the apps you'll need to make your Linux installation nice and polished.
Installing Acrobat Reader
You don't need Adobe's Acrobat Reader in order to read PDFs in Linux. There are a number of programs that come by default with your installation that will do the job. However, some PDFs come with features that you can only take advantage of with Acrobat Reader, so at some point you might decide that you want it.
To install Acrobat Reader in your distribution:
- Fedora - See the Unofficial Fedora FAQ.
- Kubuntu and Ubuntu - See the Acrobat Reader Installation Ubuntu Tutorial
- Mandriva - Purchase the Mandriva Linux PowerPack, or go to Adobe's download section.
- openSUSE - Use your package manager. Acrobat is in the Misc. Proprietary Packages section.
Installing Flash
Depending on your distribution, you may need to download Adobe Flash Player or it may come on the installation media. Mandriva Club (paid) members will find Flash available in the Commercial packages section of their package manager. Everyone else will need to use these resources:
- Fedora's FedoraFAQ
- Kubuntu, use Ubuntu's UbuntuGuide
- Mandriva (unpaid) users can get Flash from Adobe's Flash site
- openSUSE users will find the Flash player in their package manager, in the Misc. Proprietary Packages section.
- Ubuntu's UbuntuGuide
Installing Java
Java is a popular programming language because you can write code without worrying which operating system you're dealing with. Some Java applications run from your desktop, while others run in your Web browser. A key bit of information is that you're looking for the Java Runtime Environment, otherwise known as the JRE.
To install Java in your distribution:
- Fedora - See the FedoraFAQ for a quick explanation.
- Kubuntu and Ubuntu - See the Java Design Concepts writeup
- Mandriva - Open up the Mandriva Linux Control Center and search for "java." Install the latest version of the OpenJDK Runtimme Environment.
- openSUSE - See the openSUSE document on Installing Sun's java on SUSE Linux.
Listening to MP3s
Plenty of people like to listen to music. Today a lot of the music either comes in MP3 files, or we put it into MP3 files. No matter how it gets there, we want to be able to listen! The problem is that the MP3 format is patented, which legally complicates a lot of things.
Mandriva users can listen to MP3s out of the box. Everyone else needs to do the following:
- Fedora - See the FedoraFAQ.
- Kubuntu - See the Kubuntu FAQ for how to add MP3 support.
- openSUSE - See the openSUSE Restricted Formats document.
- Ubuntu - See the Ubuntu Restricted Formats document.
Handling Graphics Cards
It is becoming more and more unusual these days for any Linux distribution to have problems with the graphics hardware on a PC. However, if you want to use all of the special features provided by that hardware, you will need to get the driver provided by the hardware manufacturer.
Installing ATI Drivers
If you're using an ATI graphics card, here's how to get the drivers for your particular distribution:
- Fedora's FedoraFAQ
- Kubuntu's ATI Driver hOWTO
- Mandriva's Wiki
- openSUSE's ATI Driver HOWTO
- Ubuntu's ATI Driver HOWTO and the UbuntuGuide
Installing nVIDIA Drivers
If you're using an NVIDIA graphics card, here's how to get the drivers for your particular distribution:
- Fedora - See the FedoraFAQ .
- Kubuntu and Ubuntu - See the nVIDIA Binary Driver HOWTO.
- Mandriva - See the Mandriva documentation about making more applications available and then search for the nVIDIA driver once you have added more software repositories.
- openSUSE - See the openSUSE nVIDIA documentation

The good thing in free software is that you have alternatives. Mostly.
In the case of Java, you definitely have. These days you can can install OpenJDK, which is a fully functional free software version of Java. In fact it functions so well, that the next major Java release by Sun is generated from this one.
In the case of Flash, there are even more alternatives, but Flash is generally a proprietary platform, and Adobe did not show intention to make it open - yet. So Adobe is running away. What that means is you can install Gnash or swfdec which are free Flash players. They work for some part of the web, and they don't work for some other part. It's a shame. But it's a shame for the web, not for the mentioned software...
I would not suggest to people just migrating from Windows those software. If you install one of them instead of Adobe's proprietary player, you will face that a large albeit shrinking part of the web is only for users of proprietary software. It's not an immediate issue for the average user, but it's a big issue for users having disabilities and users certain about their freedom.
So if you care about your freedom, use free alternatives of Flash: swfdec or Gnash!

ow to Use CYDIA
ow to Use CYDIACydia is the new and improved source for all your third party apps not found in the AppStore or regular iPhone. Over 500 applications and extras for download - free of charge! Below is all you need to get the most out of Cydia and its features: 1. Click on the new Cydia icon on your Springboard.
Wait patiently while it loads all sources and takes you to the welcome screen. 2. Upgrade Cydia (if required) From here if you haven’t run Cydia in a while, or this is your first time running, you may get a notice about ‘Essential upgrades’. These are upgrades to the Cydia application itself that may be required for installing new packages and apps:
NOTE: After installing essential upgrades, it’s always a good idea to restart Cydia to make sure the new packages are reloaded. Repeat Step 1 to open Cydia again (though you probably already guessed that). 3. Update Applications If you’ve installed applications previously you may see a numbered notification next to the “Changes” menu. This indicates that there are updates available for currently installed applications. For our walkthrough I’ll update the NES emulator I downloaded a couple of days ago. To update applications:
You’ll notice on the last shot that NES has disappeared from the list and the notification NOTE: Changes also contains applications that have recently been added or changed, this is a good place to go to find new applications on a regular basis. 4. Installing New Applications Let’s install something new. I love Pac-Man, and it just so happens that the developer of Mac-Man, a great Pac-Man clone, is available on Cydia under the games category. To install an application:
You will see it run through a series of steps . . . Downloading . . . Preparing . . . Complete.
Now Macman is successfully installed, you should be able to hit your home key, wait for your homescreen to refresh, and a tempting new Macman icon will be waiting for you. Let’s go eat some ghosts!
5. Removing or Reinstalling Applications Ok, so now you have an application installed, but you don’t really want to play it anymore. Removing it is as simple as a few taps:
6. Searching for Applications One of my favorite features of Cydia is Searching. I can find an app without having to go through countless categories because I can’t remember where it was located:
The list is filtered as you type, and all matching applications are shown. Select one to install and follow step 4 above.
Check the Changes section in Cydia daily for updates. New applications are always being added and updated. Check Out Our Cool Cydia Applications for More Fun Apps To Download!

Cycorder is a Video Recorder for your iPhone. This is a powerful app that lets you record at least 5 hours of video and sound. Very good video quality. .
The only real functionality for Cycorder at present is simply this: clear, seamless video. It encodes immediately, so there is no significant wait time as compared with iPhone Video Recorder. You point, click on the round record button icon, and when finished, click it again. Your video is there to view in a list, immediately. It is also labeled clearly and without confusion. To begin recording just tap on the little round icon down on the bottom of the screen. It will then turn red which means recording has started. Just tap on the icon again to stop recording. Just tap on the upside down arrow on the lower left side of the screen and it will bring you to a list of all your recordings. There are no other features at present. Pressing the edit button simply allows you to delete the video. You can SSH into the iPhone to grab your video, but there is no interface to share or export your video from the phone. Features:
One nifty feature of Cycorder now is that if you exit the app while recording (pressing the home button), it will continue recording! This allows you to check on email or whatever while it is recording in the background!
Cycorder records in .mov format at 7-15 fps. The result is exceptionally clear video. Cycorder is very easy to use and will bring the most out of your iPhone. Enjoy!!!
