Linux 学习笔记3： 重装 及 安装chrome

重装Linux

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

 

发现 Ubuntu 有时候会莫名其妙地出现故障，于是决定重装。

昨天重装过一次，重装过程中，若是把新的Linux重回原来的旧的分区，而不是把旧分区删除重新分区，这样重装的Linux里还会保留原来的Linux的文件，等于没有重装！因此，重装 Linux时必须把原来的分区删除，重新分区。

装chrome

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

 

原来chrome必须在用超级用户登录才可以安装成功，否则，普通用户打开Chrome安装文件后会没有响应。

 

装firefox 的flash插件也是如此。

如何在 Ubuntu 用reboot 等命令

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

 

原来Ubuntu在默认的情况下，把root用户已经锁定住了，即用户不能以超级用户的身份登录的。

 

 

default root account is locked under Ubuntu Linux. Therefore, you cannot login as root or use 'su -' command to become a superuser. To run all administrative command use sudo command. sudo allows a permitted user to execute a command as the superuser or another user. Ubuntu setup your default account (the one created during installation) to run all administrative commands.

For example create a new user called bar, you need to type sudo command as follows:

$ sudo adduser bar

Password:

 

所以要用reboot这个命令就必须以管理员身份登录,然后在命令行输入   sudo reboot  ， 并输入管理员密码就可以了。

呵呵， Ubuntu真是的。

有个问题，如何使Ibus每次系统启动时其跟着启动？

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

Ubuntu
系统安装后已经自带了ibus输入法，在英语环境下默认不启动。

配置ibus自动启动可以在Ubuntu
系统菜单上选择System — Preferences — Startup Applications，在该窗口中增加一个程序：

 

Name: ibus-daemon

Command: ibus-daemon -d -x -r
