Linux 學習筆記3： 重裝 及 安裝chrome

重裝Linux

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

 

發現 Ubuntu 有時候會莫名其妙地出現故障，於是決定重裝。

昨天重裝過一次，重裝過程中，若是把新的Linux重回原來的舊的分區，而不是把舊分區刪除重新分區，這樣重裝的Linux裡還會保留原來的Linux的檔案，等於沒有重裝！因此，重裝 Linux時必須把原來的分區刪除，重新分區。

裝chrome

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

 

原來chrome必須在用超級使用者登入才可以安裝成功，否則，普通使用者開啟Chrome安裝檔案後會沒有響應。

 

裝firefox 的flash外掛程式也是如此。

如何在 Ubuntu 用reboot 等命令

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

 

原來Ubuntu在預設的情況下，把root使用者已經鎖定住了，即使用者不能以超級使用者的身份登入的。

 

 

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這個命令就必須以管理員身份登入,然後在命令列輸入   sudo reboot  ， 並輸入管理員密碼就可以了。

呵呵， Ubuntu真是的。

有個問題，如何使Ibus每次系統啟動時其跟著啟動？

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

Ubuntu
系統安裝後已經內建了ibusIME，在英語環境下預設不啟動。

配置ibus自動啟動可以在Ubuntu
系統功能表上選擇System — Preferences — Startup Applications，在該視窗中增加一個程式：

 

Name: ibus-daemon

Command: ibus-daemon -d -x -r
