Too many reasons to install ubuntu 10.04 lucid lynx in your system


It’s that time of the year again—another Ubuntu version is being released today, April 29th. To celebrate, we’ve put together a gaggle of screenshots, and reviewed the two biggest features to be offered in Lucid: social networking integration, and the Ubuntu One Music Store.


Ubuntu One Music Store


The new Ubuntu One Music Store is being touted as iTunes for Linux. This music store sells high-quality DRM-free MP3 music files for $0.77 USD. Users purchase this music via the Music Store in Rythmbox (plugin available for AmaroK and Banshee), logging in with their Ubuntu One account. If users don’t have an Ubuntu One account, they are required to register one (it is free). After a song or album is purchased, it is automatically backed up onto the user’s Ubuntu One storage account.

So, what’s it like, you ask? Very nice, actually. Browsing through the music selection reveals a wide range of music available from modern artists like Lady Gaga and Breaking Benjamin, as well as obscure artists, such as Blue Lunar Monkey. The music can be searched by album, artist, song, or genre.

The Music Store is very well organized. Clicking on an album or song will bring you to a concise page that lists all the songs on that particular album, as well as a preview feature, album artwork, relevant information, and the ability to download.


To buy the song, users must click “Download”. This will bring you to a summary purchase page, where you can review the information and, if you’re sure you want to purchase said song or album, you can proceed to checkout. You can go back to the store and download more songs, then pay for them all in one lump sum to make things simple. As far as I could tell, you can also remove songs from Checkout that you decide you don’t want.


For first-time users, billing information will need to be added. This information is then saved to make future purchases faster.


Unfortunately, you cannot pay with a Paypal account (which isn’t a big surprise anyway). You must plug in the info for a Visa or Mastercard, plus your country and zip code. All information is secure, but paranoid individuals can use a prepaid Visa or Mastercard (I know this because I used a prepaid Visa).


Once the relevant information is provided, the song will be downloaded to your Ubuntu One account, where you can then access if from any computer and download as many copies as you please, including burning them to CDs and copying them to different portable players.


Is it an iTunes substitute? Yes and no. You can’t use iTunes on Ubuntu, obviously, so it is certainly a convenient and handy way to legally purchase and download music, and is much, much, much easier to use than Amazon’s bloated download contraption they call software (mandatory for purchasing music from Amazon). With that said, calling it an iTunes substitute isn’t really true; iTunes offers podcasts and eBooks, plus video content, while the Music Store does not. Overall, the Ubuntu One Music Store is a very good first step in the right direction.

Social Networking


Ubuntu Lucid Lynx seems to be targeting the younger crowd—namely, the social marketing crowd. The wonderful application known as Gwibber is now integrated into the desktop in such a way that users can manage their Flick, Facebook, Twitter, chat, and other various accounts from one easy-to-access menu on the desktop panel.

Is this feature convenient? Absolutely. I was able to update my Facebook status in less than five seconds between working and emailing via the little drop down menu by the log out button.


What’s better, you can click that little envelope icon, choose “Broadcast Accounts”, and it will pull up Gwibber, where you can toggle through your various social networking accounts, view friends updates, upload images, and more.

If that wasn’t cool enough, you can set up a variety of different options and customizations that apply to your accounts.


Are these additions worthy, you might ask, or are they fluff that simply took up time that could have been used for those things. The answer to that is….maybe fluff, maybe not. That depends on you. For someone like myself, who works from home and frequently toggles between social networking accounts, chat, and email, these integrated features are a wonderful addition that streamlined connectivity and made it as integral on my computer as it is in my life.

Appearance


For anyone who has spent any appreciable amount of time using Ubuntu, the first thing you would have noticed upon peeking at the beta screenshots was the slap of color—purple, to be exact. Having come from a long-line of desert colored themes, Lucid’s smear of color is very appealing, as are the nice icons lined up on the desktop panel’s right side.

We don’t really have much to say in terms of the theme: some find it beautiful, others are ‘meh’ about it, and others hate it. Instead of telling you what we think (it’s awesome!!!), we’ll give you a full screenshot and let you form your own opinion.


Bugs


And now for the sad part. Yes, Lucid has gone through a ton of beta-testers who have dutifully reported bugs. As is always the case, however, some squeaked by, and they’ll be fixed in due time. Here are the couple we came across.

Ping Tab Crash

If you select the ‘ping’ tab in the Network Tools under System Administrator, the dialog crashes and you get a warning that the utility crashed unexpectedly.

Screenshots

It seemed like no matter how fast I pressed the screenshot button, the screenshot dialog would appear seven or eight times. I would have to accept the first one, then cancel the rest. This happened while taking a dozen different screenshots.

Wifi

Erm, this isn’t so much a bug as it is a nuisance. I have used the last four editions of Ubuntu on the same laptop (Dell Latitude D620), and this is the first one that hasn’t worked out of the box. In fact, the wifi is still giving me problems. Lucid recognized my hardware and connected to both Ethernet and WiFi without problems. There was a DNS problem, however, and it wouldn’t load any webpages.

After editing config files and plugging in gateway IPs manually, it spontaneously worked after almost four hours of twiddling…then stopped working an hour later for no apparent reason. I’m yet to get it to load any pages.

The same thing happened on my Asus laptop.

This may not be a bug—this might just be my just desserts after having such an easy experience with Ubuntu for so long. Who knows. This problem is very real, however, and very frustrating, so I highly recommend playing with that LiveCD first and making sure that everything runs smooth on your system before installing.

Improve speed of Linux


When people hear about Linux, they either think about speed, or about being really confused. Either way, sometimes Linux runs a little slower than you’d like. Luckily you can speed the system up a little bit (or a lot, depending) using one or more of the simple tricks below.


Remove Unnecessary Apps

This happens to many computer users—they see an app, think it looks cool and useful, then download it and never use it again. These apps build up overtime and bog a system down. Start uninstalling apps you don’t need and your system should increase in overall speed.

Reduce Start-Up Apps

There are a number of different processes that start up when you first boot, and probably don’t use most of them. The startup processes will vary based on the distro, but all have the same effect—they slow things down. Pull up the startup processes (which will also vary based on distro), disable them, and they won’t slow things down anymore.

Reduce Swap Space

Swap space is for people too cheap to buy RAM (ok, so maybe you’re using old hardware). Swap space is basically an empty part of your hard drive that has been reserved specifically for swapping info out with the RAM. If you have a lot of processes going, your system will swap the data in the RAM with the data in the swap space as a way to let you run more apps. The problem is that this is a slow process, and unnecessary if you don’t need it.

Increase App Memory

Some programs will slug along, making it appear that your system is slower than arctic ice, when in reality, the program is simply being starved of adequate memory. Crack open the help files and see if there is a way to increase the memory for that particular application. If there is, increase it and things should speed up.

Burp Your Apps

Alright, this might sound odd, but so does “bloated apps” if you think about it. By ‘burps apps’, we mean, “Uninstall the crapware”. Some people might gasp at this suggestion, not because they think it won’t work, but because of the insinuation that Linux has bloatware. Sorry, but it’s true. Some programs for Linux are just too clunky, chunky, and memory hungry to have on a fast machine. Burp your apps and notice the speed increase.

Increase RAM

This isn’t a software tweak, but oftentimes it can make a big difference. Look for a small flap on the back of your laptop (or a slot inside the your tower) and add some more. Going from 1GB to 4GB will make a big difference in many cases.

Disable Eye Candy

Those sweet Compiz tricks, those menu effects, those fancy mouse pointers and jumping icons are all nice for showing your friends how awesome Linux is, but isn’t so great when it comes to getting maximum speed on your system. Depending on how many things you are running, those graphics can slow a system down considerably. Disabling the various effects will greatly speed a system up.

Eliminate Hardware Bottlenecking

You end up with a bottleneck when one piece of hardware is faster than another. This can happen because you have a slower-than-dirt hard drive, a slow CPU with a fast graphics card, etc. Look at your hardware, make a list if you need to, and update things that are slower. On the other hand, make sure your system isn’t slowing down your hard drive as a way to insure stability.

Update Kernel

A newer kernel will, in most cases, be faster than an older one. If you’re running an old kernel, update it, or switch to a different distro with a kernel that plays nicer with your particular hardware.

Changing File Systems

If you’ve been running the same system for awhile, you might be using an older, slower file system. Updating from EXT2/3 to EXT 4 will speed things up a bit, though it will likely necessitate a complete system overhaul, which might speed things up as well.

Use Command Line Apps

Technically, all apps are command line. The wonderful geeks of the world then add a graphical user interface, most commonly called a GUI, which gives you a nice program to click and point in, making it easier for the everyday user or someone unfamiliar with the program to use. The downside to a GUI is that it automatically makes an app a little more bloated then it otherwise would be. You can reduce its impact on your system by using it as a command line app, and only requires a little bit of memorization.

Eliminate Boot Timer

If you use GRUB, then you’re no doubt familiar with the annoying little timer that counts down when you first start the computer up. That timer is handy if you are dual-booting, but mostly just annoying if you’re only running Linux on the machine. To speed the boot-process up a little bit, crack open the Terminal and edit the ‘grub’ file, changing the timer countdown value to ‘0’.

Remove Menu Icons

Menu icons are mostly useless if you’re capable of reading, especially since most users concerned with speed already have shortcuts to launch their favorite apps. To get rid of that delay that happens when you click on the menu, disable the icons. This can usually be done by right-clicking on the menu and unchecking the box for displaying icons.

Change Desktop Environment

If you’re using Linux, there’s a good chance you’re using either Gnome or KDE. KDE is even slower than Gnome, but both are slower than many of the other systems available. If you still want menu bars but don’t want to be as bogged down, look at the XFCE desktop environment. If you’re really looking for speed, you can download Fluxbox, Icebox, or Blackbox, all of which are as Spartan as you can get. Some distros come with these desktop environments preloaded. With others, you need to download them and switch. Don’t worry, the process can be reversed in case you don’t like how it functions.
