The panel encountered a problem while loading Gnome desktop applet
Last time while I come to desktop after starting my Ubuntu 10.10 (Maverick Meerkat) machine, a message appear infront-of me. A dialogue box say:
The panel encountered a problem while loading "OAFHD:GNOME_NotificationAreaApplet".
Do you want to delete the applet from your configuration?
I click on Dont Delete. I restart my computer and everything goes fine. No any warning message shows its ugly face anymore. I searched google if there are anybody facing this kind of problem. I found many result. I understand that this problem occurs when applets start on panels. I add 20 applet on top panel. It is a heavy panel to load quickly. Dont blame me for this practice. I am a Ubuntu guy man. And I leave windows for greed of this kind of customisation ability. But what about the problem?
I found that when you see this kind of crash report, please restart of simply logout and login again. Wish to solve the problem.
You can try some more way to solve it.
Create a new user and use this account.
Reinstall gnome-applets and gnome-applets-data from synaptic package manager.
Logout and login again
Update/upgrade system. (System should fully patched and updated)
The sheer variety available to the Linux desktop brings with it a level of discussion and debate most other platforms do not know. Which desktop is the best? Should Linux hold onto what has always worked? Should the Linux desktop mimic what others already know? Dare Linux look and feel like OS X?
That last idea is a bit of a conundrum � one with multiple arguments. First and foremost, there is no debating that OS X is a fast-growing platform. It not only has deep roots in Linux architecture, it has been accepted by numerous types of users. There have been many attempts at �cloning� the OS X desktop on Linux. Some of those clones have succeeded, to varying levels. One in particular (PearOS) succeeded so well it was bought by an unknown American company and removed from existence. That company is rumored to be Apple (a Black Lab Linux developer announced (in a goodbye letter) he was leaving the team to join Apple �...in a Linux endeavor they recently acquired.� Its fairly easy to put that two and two together.) But still, until there are facts, it is conspiracy, at best.
But what is it about OS X that not only draws the users, but has Linux developers scrambling to clone? One fact that cannot be denied about OS X is the consistency found throughout. No design element has been overlooked and every window opened retains the overall look and feel better than any other desktop. Beyond that, you have to start looking at apps...even more specifically, the likes of iTunes. Since the smartphone has become such an incredibly integral component of day-to-day life, users rely upon the tools to keep those devices in sync with their data. Whether you like the app or not, few apps do a better job of syncing multi-media and other data as does iTunes. Without something similar � Linux loses out.
Matthew Garret, in his essay The Desktop and the Developer proposes that �A combination of improved desktop polish and spending effort on optimising developer workflows would stand a real chance of luring these developers away from OS X with the promise that theyd spend less time fighting web browsers, leaving them more time to get on with development.� Improved desktop polish. That statement alone should ring very true with Linux desktop designers across the globe. I would add modern to that � Improved modern desktop polish � because users are no longer happy with the likes of flat desktops, such as Gnome 2, Fluxbox, or KDE. Users, especially the average user, wants polish, they want something that looks as modern as the mobile tools they use. Distributions, such as Ubuntu, have gone to great lengths to take that idea of consistency and elegantly apply it throughout. Unity does an incredible job of working the look and feel of the design to every aspect of the desktop. Linux Mint also has grown, leaps and bounds, with unifying the look and feel of the desktop. Have Ubuntu and Mint caught up to OS X? With respect to unification of look and feel, its becoming a very close race. As for application familiarity, thats another debate all together.
OS X-Like Linux Distros
As for distributions cloning OS X, PearOS has been forked, but even the fork is running into some levels of resistance. At first it was named Clementine and showed promise. The distribution then ran into legal issues with the name (the original name belongs to my media player of choice, Clementine). Now, Klementine OS is nowhere to be found. Beyond the conspiracy theories, beyond the purchasing and obfuscation, why would a Linux distribution want to mimic the look and feel of OS X? When you do a search for �OS X Linux clone�, you generally come up with the following distributions:
PearOS
Elementary OS Luna
Clementine (now Klementine)
Red Star OS.
After much digging, I discovered yet another Linux distribution with a desktop aimed at resembling OS X. This distribution is called Pirum OS. This distribution was started by high school developer Tyler Wolf and, almost as quickly as it started, was re-branded into The Pear Project. No development, no signs of life. This disappointment sent me reeling back to Google to discover LuninuxOS. Outside of having a double-take of a name (its pronounced loon-e-nux o-s), the platform has a single idea: that an alternative computing operating system should be beautiful, simply, fast, reliable and fun. After a bit of digging, it turns out this distribution is also no longer in development.
Why try to clone OS X?
All of this leads me to a single question: With so many challenges (some legal), why do developers insist on attempting to create an OS X clone of Linux? Ive scoured through the various pages of the different distributions to seek out that answer. There are numerous conclusions to draw:
The developers want to mimic the OS X look because of its popularity
The developers feel the familiarity of the OS X interface will draw users
There is some truth to the ease-of-use claims that surround OS X.
Once you give some of these distributions a try, you quickly come to realize that some are simply a standard GNOME (in most cases) desktop with a Dock and a Panel. Once you get beyond the theme of the desktop, there is little OS X to be found. You wont find iTunes or any of the other software stacks that draw people to Mac. What you will find is the standard Linux software. And that is nothing to hide. In fact (outside of the desire to look like OS X), when you examine the single most common goal of all of the OS X clones to have come and gone, you have one common goal: Beauty. All of these clones want to emulate what is often considered the de facto standard when it comes to elegance on the computer desktop: OS X. But by whose standard? Compare OS X to some of the modern Linux desktops, such as:
Unity
GNOME 3
Deepin Linux.
All of a sudden, OS X doesnt look so modern. In fact, OS X is still hanging on to the same metaphor its used for thirteen years. The true beauty to OS X stems from the hardware, not the software. Install an OS such as Ubuntu 14.10 or the latest Deepin Linux on a Macbook Pro Retina and see what real, modern elegance looks like.
Focus on innovation
With every OS X project that comes and goes, hardship seems to follow. Either its crossing the boundaries of copyright (and having the project closed), failing to drum up enough developer interest to get the project truly off the ground, or having the project purchased (insert your own conspiracy theory here). So the big question still remains. Why? Why not focus on doing what Linux has always done better than any other platform � innovate. If you want to create a platform similar to OS X, take what Apple has done well and blend it with what Linux has done well and create something completely unique. Remember, trademark and patent law is very confusing and challenging. The owners of those patents will go out of their way to prevent you from infringing on what theyve created. Dont think, for a second, that the likes of Apple will allow someone to perfectly mimic their desktop without putting up a fight. Some outstanding distributions have come and gone because they desperately wanted to cling to what Apple was doing. PearOS was a darling among a large crowd and could have gained a strong foothold for the Linux desktop. It disappeared in a shroud of mystery. Is it an impossible battle to fight? All in the name of cloning something that people either love or hate? No matter how you slice it, Apple is mighty. We may never know if they flexed that might to prevent a clone desktop from gaining any momentum. What we do know is that Linux is the king of innovation and will continue to enjoy a number of brilliant and modern desktops.
This tutorial is the textversion of the original found here: link
This tutorial shows how you can set up an Ubuntu 10.10 (Maverick Meerkat) desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge. I want to say first that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you!
1 Preliminary Note

Lots of our desired applications are available in the Ubuntu repositories, and some of these applications have been contributed by the Ubuntu community.
As you might have noticed, a few applications are redundant, for example there are two CD/DVD burning applications in my list (Brasero, K3B). If you know which one you like best, you obviously dont need to install the other applications, however if you like choice, then of course you can install both. The same goes for music players like Amarok, Banshee, Rhythmbox, XMMS or browsers (Firefox, Opera). I will use the username falko in this tutorial. Please replace it with your own username.
2 Installing The Base System
The installation of the base system is easy as 1-2-3 because the Ubuntu installer doesnt offer a lot of options to choose from, so you cannot go wrong. Download the Ubuntu 10.10 desktop edition iso image from http://www.ubuntu.com/desktop/get-ubuntu/download, burn it onto a CD, and boot your computer from it:
Select your language and click on the Install Ubuntu button to start the installation:
On the next screen you see a few requirements for the Ubuntu 10.10 installation (the system should have at least 2.6GB available drive space, should be plugged into a power source (to make sure that the system doesnt shut down during installation because of an empty battery), and should be connected to the Internet). Please check the Download updates while installing and Install this third-party software (this will install the software necessary to process Flash, MP3, and other media files) checkboxes and click on Forward:
Now we come to the partitioning of our hard disk. Usually Erase and use the entire disk is a good choice, unless you need custom partitions and know what youre doing. Erase and use the entire disk will create one big / partition for us:
Select the hard drive that you want to use for the Ubuntu installation:
Then choose your time zone:
Change the keyboard layout, if necessary:
Type in your real name, your desired username along with a password, and click on Forward:
Afterwards, Ubuntu is being installed. This can take a few minutes, so be patient:
After the installation, you will be asked to reboot the system. Click on Restart Now:
Your new Ubuntu system starts. Log into the desktop with the username and password you provided during the installation:
This is how your new desktop looks:
Now the base system is ready to be used.
Now its time to check for updates and install them. You can start the Update Manager by going to System > Administration > Update Manager:
The Update Manager tells you which updates are available (you can click on the Check button to refresh the list). Click on Install Updates to install them:
Type in your password:
The updates are being downloaded and installed (this can take a few minutes):
When the update is complete, click on Close (if a new kernel was amongst the updates, a system restart is required to make the changes effective. If this is necessary, you will see a Restart Now button. Click on that button to restart the system.).
The system is now up-to-date.
4 Flash Player And Java
If you have checked the Install this third-party software checkbox during installation, the Flash Player and Java should already be installed on the system. To check this, open Firefox and type about:plugins in the address bar. Firefox will then list all installed plugins, and it should list the Flash Player (version 10.1 r85)...
... and the IcedTea (Java) plugins among them:
5 Inventory Of What We Have So Far
Now lets browse all menus to see which of our needed applications are already installed:
You should find the following situation ([x] marks an application that is already installed, whereas [ ] is an application that is missing): Graphics: [ ] The GIMP [ ] F-Spot [ ] Picasa Internet: [x] Firefox [ ] Opera [x] Flash Player [ ] FileZilla [ ] Thunderbird [x] Evolution [ ] aMule [x] Transmission BitTorrent Client [ ] Vuze [x] Empathy IM Client [ ] Skype [ ] Google Earth [ ] Xchat IRC Office: [x] OpenOffice Writer [x] OpenOffice Calc [ ] Adobe Reader [ ] GnuCash [ ] Scribus Sound & Video: [ ] Amarok [ ] Audacity [ ] Banshee [ ] MPlayer [x] Rhythmbox Music Player [ ] gtkPod [ ] XMMS [ ] dvd::rip [ ] Kino [ ] Sound Juicer CD Extractor [ ] VLC Media Player [ ] RealPlayer [x] Totem [ ] Xine [x] Brasero [ ] K3B [ ] Multimedia-Codecs Programming: [ ] KompoZer [ ] Bluefish [ ] Quanta Plus Other: [ ] VirtualBox [ ] TrueType fonts [x] Java [x] Read/Write support for NTFS partitions So some applications are already on the system. NTFS read-/write support is enabled by default on Ubuntu 10.10.
6 Configure Additional Repositories
Some packages like the Adobe Reader are not available in the standard Ubuntu repositories. The easiest way to make such packages available to your system is to add the Medibuntu repository. First we open a terminal (Applications > Accessories > Terminal):
First off, we edit /etc/apt/sources.list...
sudo gedit /etc/apt/sources.list
... and enable the maverick partner and Ubuntu Extras repositories (if they are not already enabled):
[...] ## Uncomment the following two lines to add software from Canonicals ## partner repository. ## This software is not part of Ubuntu, but is offered by Canonical and the ## respective vendors as a service to Ubuntu users. deb http://archive.canonical.com/ubuntu maverick partner deb-src http://archive.canonical.com/ubuntu maverick partner
## This software is not part of Ubuntu, but is offered by third-party ## developers who want to ship their latest software. deb http://extras.ubuntu.com/ubuntu maverick main deb-src http://extras.ubuntu.com/ubuntu maverick main [...]
Then save the file. To enable the Medibuntu repository, please do the following: Import the repository:
to make Synaptic display packages from third-party repositories.
7 Install Additional Software
To install additional applications, open the Synaptic Package Manager (System > Administration > Synaptic Package Manager):
Type in your password:
In the Synaptic Package Manager, we can install additional software. You can use the Quick search field to find packages. To select a package for installation, click on the checkbox in front of it and select Mark for Installation from the menu that comes up:
); //
If a package has a dependency that needs to be satisfied, a window will pop up. Accept the dependencies by clicking on Mark:
Select the following packages for installation (* is a wildcard; e.g. gstreamer* means all packages that start with gstreamer):
amarok
f-spot
gimp
flashplugin-installer (necessary only if you didnt check the Install this third-party software checkbox during installation)
amule
audacity
vuze
banshee
bluefish
dvdrip
filezilla
ttf-mscorefonts-installer
gnucash
gstreamer* (necessary only if you didnt check the Install this third-party software checkbox during installation)

xine-plugin
thunderbird
virtualbox-ose
skype
After youve selected the desired packages, click on the Apply button:
Confirm your selection by clicking on Apply:
The packages are now being downloaded from the repositories and installed. This can take a few minutes, so please be patient:
You might have to answer a few questions:
After all packages have been installed, click on Close:
8 TrueType Fonts
To check if the TrueType fonts have been installed correctly, open a word processor like OpenOffice. You should now find your new Windows fonts there:
9 Inventory (II)
Now lets check again what we have so far by browsing the menus again:
Our inventory should now look like this: Graphics: [x] The GIMP [x] F-Spot [ ] Picasa Internet: [x] Firefox [ ] Opera [x] Flash Player [x] FileZilla [x] Thunderbird [x] Evolution [x] aMule [x] Transmission BitTorrent Client [x] Vuze [x] Empathy IM Client [x] Skype [ ] Google Earth [x] Xchat IRC Office: [x] OpenOffice Writer [x] OpenOffice Calc [x] Adobe Reader [x] GnuCash [x] Scribus Sound & Video: [x] Amarok [x] Audacity [x] Banshee [x] MPlayer [x] Rhythmbox Music Player [x] gtkPod [x] XMMS [x] dvd::rip [x] Kino [x] Sound Juicer CD Extractor [x] VLC Media Player [ ] RealPlayer [x] Totem [x] Xine [x] Brasero [x] K3B [x] Multimedia-Codecs Programming: [x] KompoZer [x] Bluefish [x] Quanta Plus Other: [x] VirtualBox [x] TrueType fonts [x] Java [x] Read/Write support for NTFS partitions
Open a browser and go to http://www.opera.com/browser/download/; select Ubuntu as the distribution and then default package and click on the Download Opera button:
A download dialogue should come up. Select Open with Ubuntu Software Center (default):

This article is a collection of "The Year of the Linux Desktop" over the years.
2013 As I came up with the title for this article, I did so fully realizing that many of you will likely groan at the thought of yet another "tis the year of the Linux desktop" article. However unlike other articles, I have actual concrete examples of why I think that its fair to suggest that 2013 could be a huge year for Linux on the desktop.
2012 In the 21 years or so since its inception, Linux has gained some amazing enthusiast street cred, but failed time and again to enter the mainstream. This year, however, may afford it an opportunity it�s never had before: to gain the momentum necessary to join the big boys in the operating system world. If that happens, Linux devotees the world over � from users to developers to even Linus Torvalds himself � may have Microsoft and Windows 8 to thank.
2011 Ever since Android has come out I have assumed the growth path of Linux (and the ultimate strategy of Google) will be Android on phones -> Android on desktops. My take on the Netbook episode is that, where customers returned Linux netbooks they returned them because they were unfamiliar.
2010 It kills me to say this: The dream of Linux as a major desktop OS is now pretty much dead.
2009 "Although I dont consider 2009 as the year of the Linux desktop, most of you will probably agree with me that this is the year of the Linux-powered smartphones. We can mainly thank Android for this as its popularity and market share has been growing at a rapid pace."
2008 When Evans Data released its survey on Tuesday showing a sharp shift toward Linux (and away from Windows) among developers in North America, the Linux world went wild. Wistful pengiun heads heralded the coming Open Source Age. But the real measure of OS success is in the number of users, not the number of developers. After all, most of the worlds PCs end up in the hands of ordinary people who have no interest in coding. Fortunately for open-source addicts, there are several signs that the coming year could bring a sea-change among end users, making 2008 the year of the Linux desktop.
2007 "This past month has seen a flurry activity from a number of players in the Linux desktop space. Red Hat, Suse, Ubuntu, Dell, Lenovo and even Intel white box system builders are getting into the act. Is the year of the Linux desktop finally upon us or is this just another flare up generated by the Linuxworld conference in San Francisco?"
2006 See, every time someone spouts off about this mythical year it just gives more fodder to the doubting thomases and plain ol anti-open-source-desktop people. and i dont blame them: it amounts to crying wolf.
You can see the trend and hope among Linux enthusiasts by reading these articles over the years. The release of iOS and Android have put a dampener on the question. PS. Urban Dictionary defines Linux as Communism in electronic form.
Last time while I come to desktop after starting my Ubuntu 10.10 (Maverick Meerkat) machine, a message appear infront-of me. A dialogue box say:
