What do you know about the three top Linux distributions?

What do you know about the three top Linux distributions? -- Linux general technology-Linux technology and application information. For details, refer to the following section. At first glance, RedHat's Fedora 12, Novell's OpenSUSE 11.2, and Canonical's Ubuntu 9.10 are almost identical to the top three Linux distributions. They are all based on the latest Linux kernel and contain open-source applications such as OpenOffice and Firefox. However, as long as you observe carefully, you will find the real difference. Each release is for different users.

At the bottom layer, all three systems use the 2.6.31 Linux kernel, but the differences between the three systems begin to emerge. For example, Fedora and Ubuntu use GNOME 2.28, while OpenSUSE uses KDE 4.3.1.

Test Environment

To keep them at the same pace, I have installed these three releases locally on a Dell-based instance, with the 2.2 GHz Intel Pentium E2200 dual-core processor (MHz front-end Bus ), 4 GB memory, 3100 gb sata hard drive, motherboard integrated Intel GMA chipset.

I also tested the three contestants installed on Sun's VirtualBox 3.0.12 virtual machine as the main operating system. Finally, I installed Fedora and OpenSUSE on the Lenovo ThinkPad R61 notebook and installed Ubuntu on the Dell Mini 9 netbook.

I have not encountered any trouble during installation. In each case, all I need to do is to insert CD, DVD, or USB memory stick and start the PC as required, let the release complete the installation by yourself.

Fedora 12

Paul Frields, Red Hat's ora Project Leader, once described Fedora as "the first choice for open-source contributors ". Therefore, if you are a senior Linux user, you will like Fedora. But if you do not, it may not be the release suitable for you.

This does not mean that Fedora is very difficult to use. Although it is not as friendly to new users as Ubuntu, most Linux users should be able to get started, even if they are not Linux developers.

Fedora 12 has many advantages, especially when using low-energy processors such as Intel Atom. After the startup, the beautiful GNOME interface is also very convenient to use. Internally, GNOME 2.28 has been optimized to deliver excellent performance on low-end hardware. Memory Management is also better than in the past. This is reflected in the fact that when you run a KVM Virtual Machine in Fedora, you can now run more virtual machines on the same hardware than before.

More interesting is that ora provides better support for Bluetooth wireless devices and network cameras. Another change I particularly like is that the network manager of Fedora now supports more network options, including IPv6.

However, enterprise users should be reminded that if you want a solid and reliable Desktop Linux, it is best to choose RHEL, and Fedora is not the ideal choice. Fedora features are rich, but it is not a release version for new users or enterprise users. However, if you are a person like me who already lives in Linux, Fedora is definitely a great choice. If readers of 51CTO.com are interested in Fedora12, take a look at the following detailed report titled Fedora 12 system, which specializes in introducing the latest technology.

OpenSUSE 11.2

I have tried hundreds of Linux distributions over the years, but I always go back to OpenSUSE. Why? Because it does help me complete the work. No operating system is perfect, but I have gained benefits and happiness in the update of OpenSUSE.

In OpenSUSE, you can easily click the Yast interface to complete almost all management tasks. This is the main difference between OpenSUSE's default KDE 4.3 desktop and GNOME-based Fedora and Ubuntu, this also makes it easy to use and access frequently-used programs and settings. However, if you want to access uncommon applications or perform system maintenance, it requires more trouble to process shell interfaces and configuration files.

OpenSUSE also allows you to easily use proprietary plug-ins such as Adobe Flash and Microsoft Windows Media and Silverlight. Other Linux releases, including Fedora and Ubuntu, can also be achieved, but you have to go around several circles.

Another convenient feature of OpenSUSE is online upgrade, which is the first major Linux release. For most releases, You need to download a new ISO image and start the upgrade. However, I successfully upgraded from OpenSUSE 11.1 to 11.2 through Wi-Fi connection on ThinkPad, which makes the upgrade very convenient.

In short, I am again satisfied with the latest version of OpenSUSE. Although I know that Novell's cooperation with Microsoft has made it unpopular in some Linux circles, I think the overall quality of this release is high enough and I will continue to use it, interested readers can experience openSUSE 11.2 preview in greater detail.

Ubuntu 9.10

The latest version of Ubuntu is still very easy to use. It has always been my recommended home operating system and has complete functions and is simple and convenient. It has the security that Windows has dreamed of and enough software. You can use Evolution to read emails, use Firefox to browse webpages, and use OpenOffice to edit documents.

If you need more professional applications, the Ubuntu Software Center can provide you with the simplest way to find, download, and install mainstream Linux Software. You can also use Ubuntu for business purposes. The partnership between IBM and Canonical will be happy to provide your Ubuntu with a complete set of business software.

However, the bad news is that Ubuntu has two problems in hardware: It is compatible with some Intel graphics chips and some hard disks.

Intel Graphics problems are real pain points. Sometimes I start to run a program and find that the screen suddenly freezes like ice. In theory, Ubuntu is accelerating Intel's integrated graphics card, but it actually causes a crash. The most reliable way to avoid this problem seems to be to recover to the old Intel display driver. I did this successfully, however, such an important issue should not appear in the official release. This is a serious problem. If Canonical does not change quickly, Ubuntu will soon lose the most popular Linux desktop in the world, but it does not affect everyone's preference for Ubuntu9.10, otherwise, there will be no such results as "Evaluation of 7 Linux releases: Ubuntu wins.
