fedora what’s this….:P

Some trivia about Fedora

What is Fedora?
Fedora is an operating system based on Linux, a collection of software that makes your computer work.You can use Fedora as a whole, or instead of, other operating systems like Microsoft Windows ™ or Mac OS X ™ . The Fedora operating system is completely free of cost to be able to enjoy and share.
The Fedora Project is the name of a worldwide community of people who love, use and free software developers around the world. We want to lead in the creation and dissemination of free code and content, working together as a community. Fedora is sponsored by 
Red Hat , the leading global provider of open source technology more reliable. Red Hat invests in Fedora to foster collaboration and incubate new technologies and innovative free software .
What makes Fedora different?
We believe in the value of free software and we strive to protect and promote solutions that anyone can use and redistribute. The Fedora operating system is not only done in free software, but also use free software exclusively to provide you. Our programmers work with Anyone can get in Fedora and change it, creating a new product with a new name.In the Fedora Project website is provided some tools in Fedora itself.Actually, Fedora is already the basis for derivatives such as Red Hat Enterprise Linux , the One Laptop Per Child XO , and the DVD Live Contentat Creative Commons.
Want to know more?
There is much more than Fedora in a great operating system. Fedora is also a wonderful community of people working together to improve free software. There are even ways to help if you want. If you want to learn more, see some of the following resources full of information about the Fedora Project, Fedora operating system and the people that make Fedora possible.

Problems related to hardware on Fedora

I observed with most of the my friends that they are having probelm with fedora n in most of the cases tht was hardware problems with fedora. as in f13 their was prblem wid sound…..bt the bug was removed in f14…..finallly we can solve the issue   by simply changing the kernel mode setting so just try it……………………………..:)hav a good luck

 

 

Problems related to hardware on Fedora

Miscellaneous problems with Intel graphics adapters

If you’re having problems like failure to start X, crashes or freezes in the GUI, the screen corruption, failure of 3D acceleration in applications or similar problems, and your problem is not specifically addressed in this page, the following measures can be taken:

Many problems can be avoided by disabling the “kernel mode setting.” To do this, add

---------------------------------------- 
nomodeset 
--------- -------------------------------

as a kernel parameter. If this solves your problem, please check if a bug has already been reported, and if not, open a new bug in the component xorg-x11-drv-intel explaining their symptoms and providing all the information normally required to report bugs of X.org . In the future, “kernel mode setting” is the only method available, and therefore want to ensure that all the problems caused by the “kernel mode setting” are resolved.

If this does not resolve your problem, another potential solution is to change to a different acceleration method. To do this, add the line:

---------------------------------------- 
Option "AccelMethod" "EXA" 
--- ------------------------------------- 
or: 
----------- -----------------------------  
Option "AccelMethod" "XAA" 
-------------- --------------------------

in the “Device” in Template: Filename . If this file does not exist, seeHow_to_create_xorg.conf for instructions on how to create it. Again, if this solves your problem, please check if a bug has already been reported, and if not, open a new bug in the component xorg-x11-drv-intel explaining their symptoms and providing all the information normally needed to X.org bug report . These old methods of acceleration will be removed in the future, then all the bugs in the new acceleration method (UXA) need to be resolved.

Predicament with several graphics adapters from ATI / AMD

If you are having problems starting the graphical desktop, crashes or freezes, corruption or poor performance in graphics adapters from ATI / AMD, you can try the following.

Some problems can be avoided by disabling the “kernel mode setting.” To do this, add

---------------------------------------- 
nomodeset 
--------- -------------------------------

as a kernel parameter. If this solves your problem, please check if a bug has already been reported, and if not, open a new bug in the component xorg-x11-drv-intel explaining their symptoms and providing all the information normally required to report bugs of X.org . In the future, “kernel mode setting” is the only method available, and therefore want to ensure that all the problems caused by the “kernel mode setting” are resolved.

If this does not resolve your problem, another potential solution is to change to a different acceleration method. To do this, add the line:

---------------------------------------- 
Option "AccelMethod" "XAA"  
--- -------------------------------------

in the “Device” in Template: Filename . If this file does not exist, seeHow_to_create_xorg.conf for instructions on how to create it. Again, if this solves your problem, please check if a bug has already been reported, and if not, open a new bug in the component xorg-x11-drv-ati explaining their symptoms and providing all the information normally needed to X.org bug report . These old methods of acceleration will be removed in the future, then all the bugs in the new acceleration method (UXA) need to be resolved.

If this does not resolve your problem, there is another configuration option.Add a line:

----------------------------------------  
Option "AccelDFS" "off" 
--- -------------------------------------

in the “Device” in Template: Filename . If this file does not exist, seeHow_to_create_xorg.conf for instructions on how to create it. Again, if this solves your problem, please check if a bug has already been reported, and if not, open a new bug in the component xorg-x11-drv-ati explaining their symptoms and providing all the information normally needed to X.org bug report .

Finally, if it still does not solve your problem, try adding this line:

---------------------------------------- 
Option "DRI" "off" 
--- -------------------------------------

in the “Device” in Template: Filename . If this file does not exist, seeHow_to_create_xorg.conf for instructions on how to create it. Again, if this solves your problem, please check if a bug has already been reported, and if not, open a new bug in the component xorg-x11-drv-ati explaining their symptoms and providing all the information normally needed to X.org bug report .

Plugins and codecs in Fedora 15

Plugins and codecs in Fedora 15

MP3 Player and Audio

NOTE : To install multiple packages then you should have the repository RPM Fusion enabled.

        • Installing the Free and nonfree repositories

We have two separate software repositories:

free – to distribute open source software (as defined by the Fedora Licensing Guidelines), but Fedora does not send for other reasons.

nonfree – for the distribution of software that is not open source (as defined by the Fedora Licensing Guidelines), which includes software with source code available publicly that “has no commercial purposes.”

$ su -c 'yum localinstall - nogpgcheck http://download1.rpmfusion.org/free/fedora/
rpmfusion-free-release-rawhide.noarch.rpm http://download1.rpmfusion.org/nonfree/
fedora / rpmfusion -nonfree-release-rawhide.noarch.rpm ' "Copy the three lines together"

The first time you try to play an mp3 file in Totem Movie Player, it will ask you to look for the MP3 decoder. While you have enabled the RPM Fusion repository as mentioned earlier, will find it and install it automatically. Just like that! Learn how to do this and much more! continue reading below.

        • To add support for mp3 audio type in terminal:

$ sudo yum -y install k3b-extras-freeworld
        • Rhythmbox

Rhythmbox is already an mp3 player better than Totem, and is the default player in Fedora 15 . You can find it in Applications -> Sound & Video -> Rhythmbox Music Player.

        • Audacity

Audacity lets you record sounds directly or import files in various formats. He has some simple effects, all necessary editing features.

$ sudo yum -y install audacity

DVD and Video players

NOTE : To install multiple packages then you should have the RPM Fusion repository enabled, as described here. If you have most likely you will be prompted to automatically search for the necessary codecs. They will be installed automatically. Simple as that!

        • Playing DVDs

In order to play DVDs you must install the appropriate codecs.

$ sudo yum -y install libdvdread libdvdnav lsdvd

These files are enough to touch your unencrypted DVDs. However, if you want to decrypt an encrypted DVD you will need library libdvdcss , which is not included in RPM Fusion because of legal issues in some countries like the U.S.. As mentioned in RPM Fusion.

Views among members of RPM Ffusion differ on the legality of libdvdcss, however, no one is ready to testify to resume the legal responsibilities.

So libdvdcss is being abandoned. See also comments on legal issues on the link above. So we have to wait and see what solution they provide.

NOTE : Livna could be a temporary solution.

$ sudo rpm -Uvh http: / / rpm.livna.org / livna-release.rpm $ sudo yum-y install libdvdcss
        • Play Videos

When you try to open a video file with Totem Media Player it will ask you to seek the necessary codecs. They will be installed automatically! If you have mp3 set additional packages that were installed as dependencies. These packages include video codecs like ffmpeg xvidcore and others.

To check if you have some of them:

$ Sudo yum -y install gstreamer gstreamer-plugins-good gstreamer-plugins-bad
gstreamer-plugins-ugly ffmpeg ffmpeg-libs ibmatroska xvidcore
  • Totem

In Fedora 15 Totem Movie Player is already installed. But if you want to play DVD files also with him:

$ sudo yum-y install xine-lib-extras-freeworld
        • SMPlayer

I prefer smplayer (mplayer’s GUI) for video playback. It supports almost any video type, external subtitles and DVD playback while you have the necessary codecs installed as described earlier.

$ sudo yum -y install smplayer

Open smplayer from Applications -> Sound & Video -> SMPlayer

        • VLC

VLC (Video Lan Client) supports almost any video without the need of installing external codecs.

$ sudo yum -y install vlc

Video Editor

        • Kdenlive

Kdenlive is a popular and effective video editor, in Portuguese.

$ sudo yum -y install Kdenlive

fedora 15 released..:)

Fedora 15 Beta

Fedora 15 is coming!  Check out the Beta!

The Fedora Project was created in 2003, shortly after the announcement by Red Hat on the discontinuation of one of his most famous systems, Red Hat Linux.Since then, the distro’s development was continued by the project, which has volunteers around the world and support Red Hat’s own

One of the biggest advantages of using Fedora is that it is free software and free.That means you can use it, pass on to other users and even assist the development team to improve the system, with suggestions, testing and searching for bugs with the creation and adaptation of new functions, for example.

Currently, programmers and technicians involved with the distribution working in Fedora 15, the next operating system version, to be launched in May 2011. Who goes looking forward to the news and would like to experience what comes around, you can now download the first beta released by the team.

But first of all, it’s always good to remember that this is a development version, it is not advisable to install it on production machines, servers, or in any other context in which issues such as stability and security are essential.

But if you have that taste for adventure and likes to be always up to date with news from the open source world, nothing more just to be prepared to know what is ahead, right? So here are the new Fedora 15 Beta!

CHANGES IN GRAPHICS MODE

This is probably the area where changes are most noticeable to the end user.After all, just a look at the desktop to start noticing that many changes have happened since the last version.

GNOME 3

GNOME in Fedora 14 Beta 3

For starters, the Fedora Project was one of those who adopted the new version of the GNOME desktop. However, unlike Ubuntu 11.04, the distro has not resolved to set aside the new GNOME Shell, adopting it in its entirety.

The changes are enormous. Basically, GNOME has remodeled the look, which implies new forms of user interaction with the desktop. For starters, this is a new bar at the top of the desktop. From there the user can check schedules, and manage some devices, most importantly, access the menus of all open applications. That’s right, now the applications no longer have the menu bar on your windows, which makes the operation similar to Mac OS X.

In the upper left corner, you find the button to access all applications installed on the machine. If the icon for the desired program is not visible, you can search for it by typing the name of the application, similar to Spotlight, Mac OS X.

Below that button is the dock that lets you manage running applications, as well as configure which programs should remain there for easy access. This is another function that has a counterpart in the Apple system. However, in the case of GNOME it was implemented with its own characteristics, distinguishing it from its “distant cousin”.

GNOME 3 requires a 3D card to work well

In addition to the Control Panel, which provides the user with a more practical way to make adjustments in the system, the GNOME Shell also provides the possibility to be operated via the keyboard, thus eliminating the use of the mouse.Obviously, this is a secondary function, but can be useful for those with poor coordination or even a defective mouse.

However, that novel has a price: GNOME 3 requires a video card with 3D acceleration to work properly. Fedora 15 supports a wide variety of plates by means of open source drivers, including those made by Nvidia, AMD and Intel. If the system can not recognize a 3D video card installed, a simplified version of the desktop is enabled, allowing even so, the user can try the new system.

The news related to GNOME and would be a lot of text to the. Therefore, we recommend that you consult the official website of the project, to learn more and to maximize the features of the graphical environment.

KDE 4.6

Konqi, the KDE mascot

Those who prefer the KDE graphical environment you can count on one of the latest software version. It’s all there, the Plasma Workspace, which brought a new look to the desktop, the numerous applications that are part of the KDE packages and even necessary for the development of programs for the platform.

The function of Activities (Activities) is easier to use, allowing you to configure which applications should be executed or closed at the same time. In addition, another tool that has gained a manager was remodeled power control (Power Management), which was rewritten from scratch, with improved performance and stability.

The KWin window manager is now able to adjust the details of the graphical environment according to the video card identified by the system, thus ensuring that you have performance problems.

The Dolphin file manager also won improvements, such as a search bar and a side panel that allows you to filter the search better. In addition, there is also a better integration with Nepomuk and the tags of “semantic desktop”.

Other environments and software

LibreOffice debut in Fedora 15

Those who prefer to leave the fight “GNOME x KDE” aside and move on to another environment also finds a solution in Fedora 15. The distro features Xfce 4.8 with all its features.

Who could not miss this selection of programs is Mozilla Firefox 4, which comes with a new look and improved performance in the category. In addition, the browser also features improvements in the management of extensions, password control, protecting the browsing history and the ability to synchronize your bookmarks with the cloud.

OpenOffice has been replaced by LibreOffice. The changes are not significant, but the user can continue to use the well-known suite of software: the Writer word processor, the Calc spreadsheet, Impress presentation software and Draw for vector drawings.

A new research tool was also incorporated into the distribution. The Recoll is able to perform searches in the most common document formats, even if they are compressed files or as attachments in email messages.

GAMES

Alien Arena, one of the highlights of Fedora 15

Who says that Linux has no games? If you depend on Fedora 15, the fun is not lacking for users. There are at least nine games ranging from first-person shooting (FPS) to kart racing played with Tux and his gang. These are in the list of games included in the distribution, the title Alien Arena, Colossus Arena, Flaw, Freeciv, FreeCol, FreeDink, gBrainy, SuperTuxKart and zas.

FOR SYSTEM ADMINISTRATORS

Of course, the Fedora Project does not leave out one of the public more interested in the distribution. System administrators have also gained more stability and security with the new versions of essential software for the proper functioning of the OS. For starters, the distro in the Linux kernel used is 2.6.38, which has a better management of resources in stressful situations or use the overloaded processing and memory.

SysVinit and were replaced by Upstart systemd, which now becomes the distribution system daemon. With code written from scratch, systemd makes Fedora 15 has a faster boot, especially when installed on a SSD.

Some changes also occurred in the directory structure. Now, “/ var / run” and “/ var / lock” are links that reference to the new / run and / run / lock . This is a change that seems to still be far from consensus in the Linux community, but Fedora comes out in front leading the new direction. If you are curious to know more about the reasons for this, see this message sent to a mailing list of the project.

GNOME 3 without 3D acceleration

In addition, server packages were also updated. The distribution includes Apache 2.2.17, Drupal6, MySQL 5.5.10, PostgreSQL 9.0.3, and the software for virtualization, such as
Boxgrinder, support for Spice in virt-manager and libvirt in numerous improvements. The Xorg X server has been updated to version 1.10 and numerous advances were made ​​in the question of hardware support.

MORE SECURITY

Before it was necessary to restart the firewall daemon (FirewallD) every change, even if minimal. Now, these changes can be made dynamically, ie without interruption of services for their actualizations. For now, the daemon has support for iptables and ip6tables ebtables. An icon appears in the system tray allows the user to enable or disable the service and check its status.

Another novelty is the concept of a group administrator, allowing registered users to it can run sudo with their respective passwords, to authorize the execution of administrative tasks and tools, also through their own passwords.

 

 

SO ENJOY THE NEW STUFFS OF LINUX……………………:)

Why i should use linux..:)

When firstly i came to know about linux. i installed it n reallly it was amazing bt i felt to much problems with linuux…bt i was continue to solve the problems…n now i can say tht linux is really to bettter thn windows..:) Here i am giving some points which will definately prove how its too better.

· Linux doesn’t have the virus problems : Even Microsoft’s CEO Steve Balmer couldn’t clean Windows Viruses. Still not convinced? Its not that there aren’t any viruses for Linux but Linux is more secure and less virus prone.
· No Spyware: Not just spyware but none of those funny applications that keep doing things in the background.
· Linux doesn’t need defragging: The Linux file systems work very efficiently such that it arranges data in a way that it doesn’t require defragging.
· Linux doesn’t crash without any apparent reasons. In Linux the core operating system (kernel) is separate from the GUl (X-Window) from the applications (OpenOffice.org, etc). So even if the application crashes, the core operating system is not affected. In Windows (Microsoft prefers to call this tight integration) if the Browser crashes, it can take down the entire operating system.
· Linux doesn’t crash if you accidentally pulled out your USB key/pen drive. Try this a 100 times if you don’t believe me. But don’t blame me if your pen drive data gets corrupt.
· Linux doesn’t require frequent re-installation: In Windows if the OS crashes, there is no easy way to recover this. Many IT support staff doesn’t know what to do and all they can do is re-install Windows. Which means that users applications and preferences are lost, and needs to be installed again. I haven’t seen anyone using Linux, requiring re-installing unless there is a hard drive failure. Most things in Linux can be fixed without requiring re-installation.
· Linux doesn’t require frequent rebooting: Linux runs extremely stable, even if an application crashes, there is no need to reboot the whole system, just restart that application or service. Linux also doesn’t require rebooting when a new hardware device is added configured. Linux doesn’t require rebooting when you change any setting or re-configure your Network or when you install a new application.
· No licensing headaches: Yes Linux is free and you don’t know need to bother about the complexion licensing of per user/per PC/per server/etc. Note: Some Linux distributions charge a yearly subscription to get the updates and patches, however this is still simpler than the proprietary world.
· 100 File Systems: Linux can read over a 100 different types of file systems. Windows is limited to its own two file systems. Well most general users may not care about this but its extremely useful is you are working in a mixed environment or you need to extract some data from a hard drive formatted on another computer.
· Source Code: You have access to the source code and the right to modify or fix things if you are a programmer. Many end users think this is not necessary but they will realize how important this is when their application vendor decides to discontinue support on an older version to promote a newer one.
· No Piracy: You can also share the software with your friends and its completely legal to do so. Didn’t your teacher tell you in kindergarten that you should share things with your friends? Linux and Open Source actually encourage that while if you do that in Windows its not only considered illegal but they will call you a pirate!
· Linux costs less , because not only the OS is free but the applications are also free. Plus since Linux doesn’t have a virus problem, you also save on the recurring cost of Anti-Virus software. Note: You may still have to pay for support/training but the overall running cost is low.
· Powerful Shell: Both Linux and Windows has shell environment Windows (know as command prompt). The shell environments in Linux (such as bash) are more powerful and you can write entire programs using the scripting language. This is extremely useful to automate repetitive tasks such as backup.
· Portability: Linux can run from a CD or can be installed on the hard drive. Windows by default doesn’t have any such option. Using live CDs such as Ubuntu/Knoppix, users can try out Linux by booting from the CD, without the need to install the operating system. Linux is extremely portable, it can also run off usb pen drives/portable hardrives/thumb drives and more.
· US government have Window Backdoors: Did you know that in Windows, there is built in back-door entry so US government can see you data as and when they like? Yes the US NSA has the key build into every copy of Windows. In Linux there is no such thing possible as the operating system is open source and can easily be detected and disabled.
· Linux has built in virtualization (XEN/KVM/Virtual Box/etc.) so you can run multiple copies of Linux or Windows simultaneously.
· Complete Driver Packages: The Linux kernel comes shipped with large number of hardware drivers. 3000 Printers, 1000 Digital Cameras and 200 webcams were supported by Ubuntu. On Windows, a lot of hardware doesn’t work until you install the driver, this problem is worse with Vista as Microsoft doesn’t allow drivers to be installed which are not supported/certified by Microsoft. On Linux, a huge percentage of today’s common hardware works perfectly out-of-the-box.
· No registry Keys: Unlike Windows, Linux doesn’t use registry. Most of the configuration is stored in plain text files, which are easy to manage/backup and transfer between systems. Registry is a pain to manage, very complex and your system configuration is stored in a proprietary format which needs special tools to open. The biggest pain with registry is when it gets corrupted, this problem is eliminated in Linux because it doesn’t use registry.
· Linux is the most documented operating systems and most of these documentations are available for free. These documents are well written and explain computing concepts too.
· No more hardware upgrades: Linux runs happily on older hardware and the hardware requirements don’t increase with every new version. If you have really old computers like Pentium I/III, you can still convert them to thin clients using LTSP and still use them. If you compare the hardware requirements between Ubuntu and Windows, you would notice that Ubuntu’s hardware requirements haven’t changed for many versions.
· Completely localized: As there is a strong community and the source code is available, Linux is localized into almost every language in the world. You can further customize it for your needs, you can easily do that.
· Excellent package management: Linux has excellent package management tools which make it easy to install and upgrade applications, Most Linux distributions makes it very easy to upgrade from one version to another.
· Excellent Development platform: If you are a developer, you will like Linux. Linux has all the development tools, libraries and compilers built in. If you are Java developer or a Web developer using PHP/Perl/Rub or doing C,C++ development, you will feel at home.
· No Hidden APIs: Windows many hidden or undocumented APIs which is used for unfair advantage to Microsoft. In Linux all APIs are completely open and documented. For example Microsoft specifies that everyone writing Internet application should use the Winsock API while Microsoft Internet Explorer doesn’t use the Winsock API, it uses an undocumented API allowing Internet Explorer to run faster than other browsers.
· No Execute by default: By default if you download any file, it doesn’t have the execute permission, making your system more secure. The app cannot execute unless you go and change the permissions.
· No write access to applications: By default users cannot install applications unless they change their permission or login as a supervisor. This ensures that any virus or malicious code cannot go and write to your application folder.
· No open ports: By default most Linux distributions have all their incoming ports blocked, thereby making their Operating more secure from network attacks.
· Centralised repository of applications ensures that you are downloading your applications/patches only from a known source only. The repository is digitally signed which ensures that only the right application and code can be downloaded and installed on your computer.
· Faster release cycle: Many Linux distributions have a fixed release cycle of 6 months which makes it easy for them to incorporate all the latest applications, bug fixes, improvement and support for newer hardware. Windows release cycle is not predictable. Takes a few years and is often delayed.
· Multiple Interfaces: While both Linux and Windows have a GUI, Windows has only one default GUI. Linux is all about choice and has a option to use different type of GUIs or Window Managers as they are know as in Linux. Users can choose from something that looks like their favourite Operating System or they can choose something that’s simple and fast. Popular ones are Gnome and KDE.
· Free Applications: Most Linux distributions come bundled with whole lot of applications such as Office Suite, Photo Editing, etc. You not only get the OS for free but you also don’t have to pay for the applications. Yes many of these open source applications such as OpenOffice.org also run on Windows but you need to find, download and install them where as there are available in most Linux distros by default.
· Linux saves bandwidth cost: The volume of Updates that Windows, Antivirus and similar applications do, is much more as compared the updated in Linux. So if you are paying for every MB that you download, its a big consideration.
· No automatic updates: Windows Vista it setup to automatically update your system by default. In Linux it will alert you for an update but you have to choice to click and apply the update. You can setup to automatic update if you like. So you can update when you like and not when your operating system decides to update.
· Chat and Social Networking: Empathy/Kopete popular IM clients on Linux are single clients that can connect to all the protocols – Facbook Chat, Google Talk, Yahoo, MSN, Jabber, ICQ, AOL and more. Twitter/Facebook broadcast from the desktop. With Gwibber client, you can view your social network status right from your desktop or update your status to all your accounts without logging onto each of them separately.
· Superb Graphics: Linux already has a usable 3D Desktop – Compiz. This makes it easy to switch and view multiple desktops simultaneously. It also adds a nice eye candy to Linux. If you still believe Linux is only for geeks, this feature will definitely change your mind. This doesn’t require you to purchase expensive graphic cards, it very comfortably works with on board graphic card.
· No annoying message like Vista keeps telling you that xyz application is trying to access your system. Vista confuses the user, either the user will always click allow or don’t know what to do.
· Easy to dual boot: Linux makes it easy for it to exist with any other operating system. If you install Linux on a system which already has Windows, Linux will not mess your Windows. Windows on the other hand messes up your Linux partition, if it finds one.
· Linux has bundled Databases such as MySQL and PostgreSQL which are extremely powerful and used in production environments. Customer doesn’t need to purchase expensive databases.
· Linux is been used for super computing clusters, most of top super computers in the World use Linux. Windows just can’t scale to that level.
· File system scalability: while NTFS file system can scale up to 16TB, XFS on Linux can scale up to 18 million TB! Yes that bigger than what you would ever need.
· Processor scalability: Linux can scale to unlimited processors. It is already running on a single system with 2048 CPUs. Windows can’t even claim to come anywhere near that number.
