24 user experiences that Ubuntu has to share

I used Linux from ubuntu7.10 and was not familiar with windows at that time. Since learning programming happens to be lamp, I think I am not familiar with it, but I have few people to learn. During this period, it has been from 8.04, 8.10, 9.04, 9.10 to the latest Ubuntu 10.04.

I really like this operating system shared with people all over the world. There are not a few people praising the system. It is particularly interesting that an old man named Yuan Meng will repost his blog post on major IT websites. He will talk about Ubuntu when he opens his mouth closed, and often uses brackets to explain it, for fear that people will not understand it.

Oh, this old man, in his 70 s, is so crazy about ubuntu. The use of ubuntu on the desktop is really good. Although it is easy to use, it is not as good as windows in terms of games. However, the spirit of openness and sharing is commendable. In addition, do the lamp line, do not use Linux, say no.

Last time I asked Jin Hao what version of your Jinshan Linux server was. He replied to Ubuntu server 8.04. Haha, I really don't believe it. After all, most of them use centos (which is the same as RedHat, more free and supports YUM). I said why I chose it, and he answered, simple, just a few commands. Wikipedia also uses ubuntu8.04. Recently, it was directly updated from 9.10 to 10.04, with a small problem. It mainly displays brightness and flash garbled characters. Compared to the previous tedious configuration, there is no configuration for this installation. I have accumulated some practical experience. The previous time the teacher asked me to write a Ubuntu document, which has never been written. I will add this document and share it with you.

1. Source list: I am a telecom user, and I have been using 163 of the source, which is not bad.

2. Check the CPU temperature. My colleague laughed at me and used the notebook for CPU and memory. If this is true, I often enter top to check which resources are occupied. CPU temperature is very important.

 
 

  
  
sudo apt-get install lm-sensors  
  
  
sudo sensors-detect 
 
 

View: Sensors

3. The palimpset disk tool is provided in 9.10. I was shocked when the prompt "one or more disks are failing" was installed. I thought the disk was broken and a bad track was prompted. Hurry up and clean up. After cleaning and restart, you will not be able to enter the system. It was reinstalled again. In 10.04, this problem is gone. View disk temperature:

 
 

  
  
sudo apt-get install hddtemp  
  
  
sudo hddtemp /dev/sda 
 
 

4. Install the hardware detection tool. Ubuntu power management has a defect. This bug has been on the official bug list but has not been taken seriously. When the power supply is used, load_cycle_count is increased twice every few minutes. At the beginning, I also looked for solutions everywhere. Later I found that this was not important at all. The disk can be load_cycle_count for more than 0.6 million times. Let's see the results of my six months of use (2373 ):

 
 

  
  
Sudo apt-Get install smartmontools // install
  
  
Man smartctl
  
  
Sudo smartctl-A/dev/SDA | grep load_cycle_count
  
  
193 load_cycle_count 0x0032 100 100 old_age always-2373
 
 

5. There are five CPU frequencies: cpufreq-info will tell you: available cpufreq governors: Conservative, OnDemand, userspace, powersave, and performance. The default value is OnDemand;

 
 

  
  
First install sudo apt-Get install cpufrequtils
  
  
Man cpufreq-Set
  
  
Sudo cpufreq-set-G powersave // set to the lowest
  
  
Sudo cpuferq-set-C 1-G powersave // set the second CPU
 
 

Open a virtual machine, high CPU is scary, motionless 130%, the temperature is soaring. No way. The CPU is set to the lowest frequency, and the temperature will not rise as the CPU usage increases.

6. The default font is not flattering. Use. Jin Hao said that Vista has made a great contribution. True or false.

 
 

  
  
wget -O get-fonts.sh.zip  
  
  
unzip -o get-fonts.sh.zip 1>/dev/null  
  
  
chmod a+x get-fonts.sh  
  
  
./get-fonts.sh 
 
 

The four-step solution, especially the Monco font, is used by gvim.

7. scim input methods conflict with many software. Ficx has heard that it is good and has never been used. After using ibus, it has not changed to another one. 9.10 is already ibus by default. However, there is no commonly used ibus Chinese pinyin before the Language Pack is updated.

Install sudo apt-Get install ibus // ibus-table is an additional code table with five strokes, Zheng code, and cangjie

 
 

  
  
Download ibus-pinyin
  
  
Sudo im-switch-C/
  
  
Sudo im-switch-s ibus
 
 

Restart x

8. The world of browsers is Firefox in Linux. However, although this gentleman is excellent, it is not a fuel-saving Lamp. Memory usage, too much CPU. Without Ajax debugging, I have to use firebug, and I rarely use Firefox. Google Chrome for Linux is a common web browser with a single word, fast. Opera10 was launched, but its share of browsers declined. However. The default font of opera is poor, and the settings in the preferences do not work. The following method is feasible.

 
 

  
  
cd ~/.opera/styles/user/  
  
  
touch user.css  
  
  
gedit ~/.opera/styles/user/user.css 
 
 

Enter the following content:

 
 

  
  
html,body,*{  
  
  
font-family:”Microsoft YaHei”!important;} 
 
 

Restart the browser and choose View> style> user.css.

9. Wireless Driver: Broadcom sta Wireless Driver 9.04 system-> System Management-> hardware driver sometimes does not exist. This is a wireless NIC Driver. Fortunately, 9.10 does not.

Command Configuration:

 
 

  
  
sudo iwconfig eth1 essid ZTE4E8DA4 key s:dfasdfd  
  
  
sudo dhclient eth1 
 
 

Wicd network management is better than the default networkmanger in wireless management. However, I seldom use tools and get used to modifying the configuration file. The three methods for configuring the wired network are as follows (without mentioning the campus network ruijie, You need to download special files)

 
 

  
  
sudo vim /etc/network/interfaces 
 
 

Static IP configuration file/etc/Network/interfaces

 
 

  
  
auto lo  
  
  
iface lo inet loopback  
  
  
auto eth0  
  
  
iface eth0 inet staticaddress 192.168.1.109netmask 255.255.255.0  
  
  
gateway 192.168.1.1  
  
  
ifconfig eth0 up 
 
 

Dynamic IP configuration

 
 

  
  
auto lo  
  
  
iface lo inet loopback  
  
  
auto eth0  
  
  
iface eth0 inet dhcp  
  
  
ifconfig eth0 up 
 
 

Dial-up Internet access sudo pppoeconf follow the prompts

10. After KDE is installed and uninstalled, the logon interface is still the KDE interface. The solution is to convert it to the gnome interface:

Run Update-usplash-theme.

 
 

  
  
sudo update-usplash-theme usplash-theme-Ubuntu 
 
 

11. virtual machines include virtualbox3.0 and VMWare workstion7. If you use VMWare, check the registration code for VMware even though zooabox is open-source. However, VMWare is indeed stable and consumes less resources.

12. OpenOffice and yongzhong office are recommended for office software. The uof SDK has not been carefully read yet.

13. Install lamp, and install the lamp kit by marking it in the new system. Everything is configured. Install sudo apt-Get install phpMyAdmin

14. Mind Map. xmind is developed by Chinese people and easy to use. URL: ximd.net

15. FTP client tools. Gftp is a good choice. I think this is not recommended in Ubuntu wiki software recommendation.

16. Cloud computing has become too popular in the past two years. I have been thinking about what cloud is and how to use it. However, ubuntuone is a private cloud. Although it is not yet brilliant, 2 GB free space, enough storage point documentation. I do not know whether it is cross-platform. Dropbox has been used in the past and can be used across platforms.

17. There is no good CHM tool. Chmsee is better than chmsee.

18. The password management tool keepassx must be used in absolute values. And cross-platform, DBM data storage.

19. MSN: sudo apt-Get install emesene QQ: Linux for QQ is never updated, and Pidgin is also good. I used to use Ubuntu's default im, but now I have replaced it with empathy.

20. The terminal gnome-terminal, konsole and terminal under KDE support segmentation, and an excellent yakuake under KDE.

21. watch movies, mplayer;

22. Database Design Tool: mysql-workbench. Simple and efficient.

23. Run the xdebug command to check the kcachegrind file. However, you need to install many software packages. Webgrind can be stored in the Apache root directory and viewed on the webpage.

24. Gimp is known as Photoshop in Linux. They are never used. It is a pity that the last half year's teacher has been unable to draw ugly crow and can be pulled.

I recently upgraded from 9.10 to 10.04 and found that the screen brightness could not be adjusted. I checked a lot of information and found that the change to the startup Item had no effect. Finally, an ATI catalyst control center is installed.
