Thoughts about ubuntu–ubuntu Newbie Series

leave a comment »

Using ubuntu likes using a knife to survive in wild. You cannot access to most of the convenient facilities you use daily.

Two weeks ago, after crying painfully for a whole night (I leaved it downloading something and went to sleep), my hard disk failed. I replaced it with a new one, and installed windows and ubuntu in it again. But I have not touched ubuntu from then on.

These days and in the next few months, I will be busy in applying U.S. graduate schools, writing personal statements, doing research on the schools’ requirements and so on. I have no time and no interest in surviving in wild; I need to stay in civilized society, using all the efficient ways to finish my works.

In my experience, if you want to use ubuntu, you’d better make good use of Firefox. When you need doing something, find solutions in Firefox extensions first. There are many programmers have the same needs as you (you will find that all your strange needs are not unique in the Internet world), they write the extensions for themselves, and publish them.

Maybe in the future, there’s a very simple and small operation system just for running Firefox, and Firefox with its extensions can do all things you want. Combing the promising web based services, desktop based on browser may come true.

Download BT–ubuntu Newbie Series

leave a comment »

There’re many bittorrent download softwares can run on ubuntu, but they cannot recognize the torrents I want to download.

If you have the same problems of mine. Try the lastest verstion of Azureus. It works well, though the download speed seems not high.

Play video in ubuntu — ubuntu Newbie Series

leave a comment »

The ubuntu 7.10 cannot play most of the media type if you don’t install package.

I have tried many ways to make it play popular video types, including rmvb, avi. Some ways may work for you, but not me.

If you don’t want to waste your time in trying many failed ways, you should try to install w32codecs first. The player in ubuntu 7.10 can play rmvb and avi now with this package, though it seems a bit darker than usual when it plays rmvb. (I don’t figure out how many media types it supports.)

w32codecs is not provided by ubuntu official sources. You must download it from web(search it in google). You may have some troubles in installing it. Find helps in ubuntu’s “help”(on your desktop tool bar) about how to install software.

Screen flashes? ubuntu Newbie Series

with 2 comments

After I had installed ubuntu on my laptop, the first problem was my screen flashes severely.

I had tried most ways given in the ubuntuforum.org to fix this problem, editing documents, installing software, but failed.

At last, I remembered a extraordinary simple way referred among hand of complex technical instructions.

Press video output button on your keyboard.

God damn! It works!

No Sound problem –ubuntu Newbie Series

leave a comment »

In Last post I write about how to install ubuntu, and syslik asked help for solving sound problem of his ubuntu.

I am sorry that I reply this help so late, and syslik may has already solved it now. syslik’s trust on me just a little scares me, as he/ she report the hardware data of his computer to me, which making me seems like a master. But I don’t know more than you.

I have found some pages about the sound problem in ubuntu, hope that helps.




Some of the information may be outdate now, but you can find most of the answers in ubuntuforums.org and google.

I have met sound problem too. It’s too low to hear clearly. This is how I solved it.

double click the sound icon on the top of the desktop


then, there’s a mixer


File>>Change Device
choose another available device, and adjust the volume, you can higher your computer sound in this way.

If this cannot solve your problem, try Edit>> Preferences, tick all the possible controls, and try them all.

Good luck!

Install Ubuntu– Ubuntu Newbie Series

with one comment

Before installing Ubuntu, you should have at least 3G free space in your hard disk. (5G is recommended.)

I assume that you have the Ubuntu CD now. (You can download the iso file from ubuntu.com  and  record it into a cd or order a copy from the

This CD is also a LiveCD, which means that you can run Ubuntu without installing it in your computer for just a try.

Insert the CD into your CD Rom and reboot your computer. (You should set your computer boot from CD Rom.)

The installation of Ubuntu is very easy, you may just be confused by the followings:

1. If you have Windows in your computer, it will ask you weather you want to import the Windows settings. I choose this function, and after installation, I can access to other partitions in the computer, that is C: D: or E: (I don’t know weather you can access the partitions if you don’t choose to import the Windows settings.)

2. In the process, it will ask you to build partitions for Ubuntu. I divide my 3G free space into two part, ext3 and swap. (These two are the types of the partition, not the names of the partitions.)

ext3 is used to stored the files (including system files and your own files if you like, or you can build another partition for your own purpose). This part should be at least 2G. (In my experience, 2G is too small, because the system files occupy near 2G.)

swap is something like virtual memory in Windows. It is used for running programs, I recommend at least as much as your computer’s memory. (My laptop’s memory is 512M, I set the swap 512M. Now, sometimes more than 300 memory and more than 200 swap is in used.)

Except above, there’s no other problem you will face when you installing Ubuntu. Have fun with it!

In the following posts in this series, I will write something about how to make your Ubuntu satisfy your daily usage, for instance, listening music, watching video.

Ubuntu, A promising desktop OS–Ubuntu Newbie Series

leave a comment »

After a few days try, I believe that Ubuntu can replace Windows as long as you just want to surf the Internet, write something, listen music and watch video on a computer.

I know Ubuntu in an article written by Wall Street Jounalist Jeremy Wagstaff. And I decide to try it since the jounalist call it a revolution of the desktop use of Linux.

A few years ago, I tried Redhat, an popular edtion of Linux. After struggling in making it run on my computer, I clean it from my harddisk. Ubuntu, another edition of Linux, doesn’t dissapoint me this time, at least up till now.

If you are a person who likes to try new things and solving problems, Ubuntu worths your try.

 Ubuntu 7.10 desktop

You can download Ubuntu or order a copy from its website ubuntu.com.

I will write Ubuntu Newbie Series to help you, who have no programming background, like me, to use Ubuntu with convenience. So, don’t be scared by Linux, we will solve any problems as long as we connect to the Internet.

Next post I will tell you how to install it in you computer.
