　　出差背两个电脑是比较辛苦的事，但是公私需要分开，使用工作的电脑处理一些私人的事情，是比较麻烦的。这种安装在ＵＳＢ上的live Linux可以方便的处理。
ＰＳ：还没有试验过，试过之后再写个report.

　　This tutorial covers the process of installing Xubuntu 8.04 to a USB flash drive from within a running (Ubuntu) Linux environment. Xubuntu uses the xfce desktop environment as opposed to Gnome or KDE. Xfce helps Xubuntu run smoother and quicker on older and slower PC's. In addition, this installation tutorial utilizes the casper persistence feature to enable changes to be saved and restored on subsequent boots. If you have access to a working Ubuntu Linux installation and your system does not have a CD drive, this tutorial is for you.

 

Basic essentials for Xubuntu 8.04 USB installation:

• Working Linux environment (we used a local Ubuntu installation)
  
• Established internet connection
  
• 1GB or larger USB flash drive
  

How to install Xubuntu 8.04 to a flash drive from Linux:

1. Insert a 1GB or larger USB flash drive (2GB+ recommended)
2. Open a terminal and type sudo su
3. As one line, type wget cdimage.ubuntu.com/xubuntu/releases/hardy/release/xubuntu-8.04-desktop-i386.iso
4. Type mount -o loop -tiso9660 xubuntu*.iso /cdrom
5. Type fdisk -l to list available drives/partitions (note which device is your flash drive I.E. /dev/sdb). Throughout this tutorial, replace all instances of x with your flash drive letter. For example, if your flash drive is sdb, replace x with b.
6. Type umount /dev/sdx1
7. Type fdisk /dev/sdx
   • type p to show the existing partition and d to delete it
   • type p again to show any remaining partitions (if partitions exist, repeat the previous step)
   • type n to make a new partition
   • type p for primary partition
     • type 1 to make this the first partition
     • hit enter to use the default 1st cylinder
     • type +750M to set the partition size
     • type a to make this partition active
     • type 1 to select partition 1
     • type t to change the partition filesystem
     • type 6 to select the fat16 file system
   • type n to make another new partition
   • type p for primary partition
     • type 2 to make this the second partition
     • hit enter to use the default cylinder
     • hit enter again to use the default last cylinder
     • type w to write the new partition table
8. Type umount /dev/sdx1 to unmount the partition
9. Type mkfs.vfat -F 16 -n xubuntu8 /dev/sdx1 to format the first partition
10. Type umount /dev/sdx2 to ensure the partition is unmounted
11. Type mkfs.ext2 -b 4096 -L casper-rw /dev/sdx2 to format the second partition
12. Remove and re-insert your flash drive (if prompted that a new medium has been detected, select to open in a new window and click ok)
13. Back at the terminal, type sudo apt-get install syslinux mtools
    
14. Type syslinux -sf /dev/sdx1
15. Type cd /cdrom
16. Type cp -rfv casper dists install pics pool preseed .disk isolinux/* md5sum.txt README.diskdefines install/mt86plus /media/xubuntu8
17. Type cd /media/xubuntu8
18. Type wget pendrivelinux.com/downloads/xu8/syslinux.cfg
19. Type cd casper
20. Type rm initrd.gz
21. Type wget pendrivelinux.com/downloads/xu8/initrd.gz
22. Reboot your computer and set your system BIOS or Boot Menu to boot from the USB stick. Save your changes and proceed to boot from the USB device

You should now be booting Xubuntu 8.04 from the memory stick and by default it should save your changes, restoring them on subsequent boots.

Notes: If your having trouble getting Ubuntu to boot, your memory stick may have a corrupted MBR. To repair the MBR of your USB device, at the terminal type sudo apt-get install lilo then type lilo -M /dev/sdx (replacing x with the letter of your flash device)

 

Super PI 是一个计算圆周率的软件,在 Windows 平台上，经常使用 Super PI 来测试 CPU 超频是否稳定，可以说，Super PI 测试是否通过已经作为判断 CPU 稳定性的依据。suxixb(http://www.shareitem.org/2007/11/29/software-super-pi/)的一篇在UBUNTU下使用Super PI让我等使用ubuntu之辈也可以享受Super PI带来的好处了了。
使用方法，请至网页http://www.shareitem.org/2007/11/29/software-super-pi/下载super PI for ubuntu,解压后放在任意文件夹，使用终端进入文件夹，执行命令
sh super_pi，就可以执行SUPERPI了

        说明：最后的 20 代表 1M（100万位），21 代表 2M，25 代表 32M。

下面是我的机器运行 sh super_pi选择 20 的结果

32秒不到，看来还是不错的。

 　　最近需要在ＸＰ下安装一些软件并作相应的测试，但是我的机子只安装了一个系统，所以使用virtuaBox安装了一个winxp的虚拟机，但是在实际使用过程中，使用USB却碰到了麻烦，启动时virtualbox会有usbfs的权限报错，修改权限后问题解决。

1. VirtualBox安装
   http://195.34.175.98/download/1.5.6/virtualbox_1.5.6-28266_Ubuntu_gutsy_i386.deb
   使用上述地址下载最新版的virtualbox，这个是for gutsy(ubuntu7.10)的，如使用其他的linux系统，请至http://www.virtualbox.org/wiki/Downloads选择相应的版本，下载完毕后双击后输入ＲＯＯＴ密码就可以完成安装。
   当然，如果你喜欢使用apt-get 来安装软件，可以参考http://www.virtualbox.org/wiki/Downloads上面关于使用源来安装软件的方法。
2. 设置USB使用权限
   需要设置两个文件的内容
   
   1) sudo gedit /etc/udev/rules.d/40-permissions.rules(你也可以使用VIM等其他文本编辑器），找到如下语句
   
   # USB devices (usbfs replacement)
   #SUBSYSTEM=="usb_device",        MODE="0664"
   改成
   # USB devices (usbfs replacement)
   SUBSYSTEM=="usb_device",        MODE="0666"
   ２）sudo gedit /etc/init.d/mountdevsubfs.sh,找到如下语句
       # Magic to make /proc/bus/usb work
       #
       #mkdir -p /dev/bus/usb/.usbfs
       #domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
       #ln -s .usbfs/devices /dev/bus/usb/devices
       #mount --rbind /dev/bus/usb /proc/bus/usb
   取消前面的＃引用标识，更改后如下
       # Magic to make /proc/bus/usb work
       #
       mkdir -p /dev/bus/usb/.usbfs
       domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
       ln -s .usbfs/devices /dev/bus/usb/devices
       mount --rbind /dev/bus/usb /proc/bus/usb

　　至此保存后，重新启动virtualbox就可以正常的使用USB了。

　　在安装新的OSS驱动之前，如果系统中还有残留的驱动文件存在，安装过程是不能够完成的，因此首先要做的就是查看一下，系统内是否有以前的驱动存在。方法如下：
1 在终端下进入目录/var/lib/dpkg/info，命令 cd /var/lib/dpkg/info
2 删除所有以oss-linux开头的文件，命令sudo rm oss-linux*
3 编辑文件/var/lib/dpkg/status,sudo gedit /var/lib/dpkg/status,找到关于oss-linux的有关内容，并将其删除（内容如下）

4 查看oss-linux当前状态，命令 sudo dpkg --purge oss-linux，则会显示如下信息
dpkg - warning: ignoring request to remove oss-linux which isn't installed.
5 安装oss-linux,命令 sudo dpkg -i oss-linux_v4.0-1013_i386.deb,安装显示信息如下
brucebot@brucebot-laptop:~/MyDownloads$ sudo dpkg -i oss-linux_v4.0-1013_i386.deb

Lenovo F31A has used many technology from thinkpad, such as Active Protection system for the hard disk(HDAPS).What is APS system? Here we go.

The Active Protection System

With the new series of ThinkPads IBM introduced the Active Protection System (APS) in 2003. The APS is a protection system for the ThinkPad's internal harddrive. A sensor inside the ThinkPad recognizes when the notebook is accelerated. A software applet then is triggered to park the harddisk. This way the risk of data loss in case of when the notebook is dropped is significantly reduced since the read/write head of the harddrive is parked and hence can't crash onto the platter when the notebook drops onto the floor.

The hardware sensor is capable of not only recognizing acceleration of the notebook, but also (to a certain degree) of its whole orientation in space, relative to gravity's axis. Furthermore, having the actual control put into software, its functionality is extendable and it gives chance to implement features like the "ignore minor shocks" feature which is present in the Windows based control applet. (This feature prevents the harddrive from parking in case of minor regular shocks such as occur when in a train or car.)
And the following websites are recorded for the future configuration for my notebook.

1.http://www.thinkwiki.org/wiki/Active_Protection_System
2.http://article.gmane.org/gmane.linux.drivers.hdaps.devel/1040

　　在使用的Nautilus文件管理器的时候，经常会无法输入文字，以下为解决方法,此解决方法在Ubuntu 7.10及SCIM输入法下测试通过。

        1.取消SCIM的自动启动: 进入终端输入　im-switch -s none，注销后重新登录。
        2. 进入终端输入 sudo gedit ~/.scim/config, 找到并设置/FrontEnd/X11/Dynamic＝true.
        3. 恢复SCIM的自动启动: 进入终端输入　im-switch -s scim，注销后重新登录

1.Introduction

I purchased a Lenovo F31A laptop days ago, it is a great laptop except the pre-installed OS VISTA, I really do not like it. As I have some experence to use ubuntu on the PC, so I decide to install the Ubuntu 7.10 to the laptop. And the installation is very easy,just download the iso file from ubutnu homepage and burn it to a CD-ROM, then use this CD to boot laptop, follow the normal way to install ubuntu. It can easily automaitcally detect almost all the hardware and install the driver to them, except two hardware, the wireless card driver and the sound driver.

WIRELESS

1.Download a software named bcm43xx-fwcutter_20060108-6build1_i386.deb and install it.Here http://linuxwireless.org/en/users/Drivers/b43 you will find more details about b43.
2.Click the icon on the right above panel---Restricted Drivers, and enable the firmware for broadcom 43xx chipset family, then it will pop-up a window ask you to slect the firmware to download, pls choose the second one which is http://xeve.de/down/wl_apsta.o ,after finishing the download,ubuntu will automatically install the firmware.

SOUND

I have tested all the alsa driver version, and some patches, which still have no effect to drive my sound card. Finally I found this article http://ubuntuforums.org/showpost.php?p=3768914&postcount=60 which help me to solve my sound card issue, so now I can listen music and watch movies under my new laptop now.
