Ubuntu is the most popular Linux desktop, the latest version Ubuntu 11.04 (code name : Natty Narwhal) has arrived a month ago with a lot of changes, modification and surprises (such as Unity is now the default desktop in Ubuntu). If you’ve been using Ubuntu from long time then upgrading to Ubuntu 11.04, may not be a good idea as Unity is almost different and so you have to customize and learn new tricks as well as keyboard and mouse shortcuts for better experience.

Unity desktop has removed the bottom panel, which is helpful in accessing opened windows and other running applications, instead of that – it has a left panel – Launcher (with auto hide features) seem almost similar to Dock Application but with some different functionality and 3D effects.

Why should you try keyboard shortcuts in Ubuntu?

Although an average computer user do not use shortcuts a lot but shortcuts can improve (a lot) the experience with Ubuntu (or any other Linux based distribution because all are 100% customizable) and it will also save a lot of time and effort, eventually resulting in better productivity. That’s the importance of keyboard shortcuts. Let’s consider an example – to open a terminal you will have to spend 3-6 seconds, if you don’t use any shortcuts, on the other hand if you use shortcut then 1-2 seconds will be enough; it means you saved 2-4 seconds in opening an applications…so finally you will save a lot of time if you apply this to some of your favorite applications or actions. The layout of unity also encourage us to use keyboard shortcuts, because there is no bottom panel is available from which we can select the apps window in single mouse click, instead of that first we have to move the mouse to launcher’s location, then launcher will appear, now we can select the desired apps.

Okay, lets come to the point – learn some cool and best keyboard shortcuts (these are default shortcuts, if you want you can customize/configure out in your way) that you can use in Ubuntu 11.04 with unity Desktop (although some of them may works with Gnome desktop as well as in older versions of Ubuntu such as 10.10 (Maverick Meerkat) or 10.04 LTS (Lucid Lynx)..just try (of course carefully) you will figure out in minutes).

Qimo is a desktop operating system designed for kids. Based on the open source Ubuntu Linux desktop, Qimo comes pre-installed with educational games for children aged 3 and up.

Qimo’s interface has been designed to be intuitive and easy to use, providing large icons for all installed games, so that even the youngest users have no trouble selecting the activity they want.

Download Qimo

In order to try Qimo, you will have to burn the ISO file to a CD-R/CD-RW as a CD Image, not as a regular file. Some CD burning software can do this, othes can’t. If yours doesn’t have an option to treat the file as an image, you can get a free program here that will.

Once you have the CD created, just leave it in your CD drive and reboot your computer. When Qimo first boots, it gives you the option to try it from the CD, or install it to your computer. Trying it from the CD means that nothing on your computer will be changed, you can reboot without the CD and everything on your computer will be exactly as it was before. This is the easiest way to try Qimo, though it will run a bit slower this way.

Linux

Linux server in the world is no doubt the ability and scalability + security + available and others. But for desktop use Linux to clean up a lot in order to meet customer needs in a variety of users ranging from the home users, the new students know computers, office users and so on.

I myself again try and experiment with all kinds of desktop Linux with parameters (demand) of my own. Here are some parameters that the author made a reference, for at least one or more suitable Linux distro for the desktop. I happened to work in private enterprise and developer PL / SQL and also concurrently the administrator.

The following parameters (in this case again I use the word need) that I managed to find within the scope around where I work:

1. Easy installation and usage
2. Easy file sharing
3. Rapid loading
4. Hurry and lightweight
5. Responship
6. Multimedia (audio and video)
7. Browser
8. Email
9. Chatting
10. Best in show
11. Drag and drop a good
12. Application shortcuts and folders
13. Stable
14. Office
15. Graphic design
16. Authoring
17. Ease of install and uninstall applications
18. Handling files (PDF, txt, png, jpeg, gif, xls, doc)
19. Stable
20. Safe (at least more resistant to viruses and spyware
and Trojan)
21. Cheap (no license and be hijacked)

Requirements above may still incomplete but at least as early starter for us-we are all in realizing Linux as a desktop solution that is appropriate for all circles. Here is also list of Linux distro I have tried a few and not so much because of time.

1. Xandros
2. Ubuntu
3. Kubuntu
4. Mandrake 10
5. Fedora Core 4
6. Lycoris
7. Knoppix 3.6
8. Simply Mepis
9. Redhat 9

Some distros I have tried the above and from some of these distributions have an advantage and a deficiency.
