从今天起，告别windows，投入ubuntu 16.04的怀抱

[vickycq]

安装的时候，提示出错：

dpkg -i 不会自动处理依赖。为何不直接从软件源安装？（位于 multiverse 区，确认软件源配置包含 multiverse）
用 apt-get -f install 自动修复依赖

根据仅有的经验，我知道下一步是输入sudo apt-get -f install 修复

1. 新手 在你不完全嘹解該指令的意義前 慎用這個指令

按照help.ubuntu.com上的提示安装也是失败：

这个源还没有 xenial 区，最大到 wily
ubuntu 软件源自带的不行么？（位于 multiverse 区 确认软件源配置包含 multiverse）

正在尝试软件源自带的，直接“apt:virtualbox-qt”。

[poloshiao]

1. sudo cat /etc/apt/sources.list.d/virtualbox.list
1-1. 你的答案可能是
deb http://download.virtualbox.org/virtualbox/debian xenial contrib non-free
1-2. 把 xenial 改為 jessie
1-3. 然後
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install virtualbox-5.0
1-4. 然後
sudo dpkg -l | grep virtualbox
看看 是不是
virtualbox-5.0 5.0.14
1-5. 補充 把 xenial 改為 wily 應該也可以 但是怕將來引起 Ubuntu 其它套件版本衝突問題 所以建議改為 jessie
1-6. 以後有了 xenial 可以改回 xenial

感谢vickycq, poloshiao两位兄弟， vbox基本配置完毕。

我是从内置的软件源直接默认安装的，apt:virtualbox-qt。也不知道到底是jessie，precise，trusy还是wily版本的。

安装好后，vbox里面安装了windows xp，目前一切正常，ubuntu里面显示如下：

确实如此，怪不得synaptics里面更新源的时候无法更新，现在改成jessie可以正常更新了。谢谢！

1. 安裝好 VirtualBox 5.0.14 要立刻安裝
VirtualBox 5.0.14 Oracle VM VirtualBox Extension Pack
http://download.virtualbox.org/virtualb ... ox-extpack
1-1. 每次 VirtualBox 升級新版本 都需重新安裝一次
1-2. 有問題 歡迎再貼文

2. 在 Virtualbox Guest 安裝好 Ubuntu
需要立刻在 Ubuntu 安裝 Guest Additions
http://www.virtualbox.org/manual/ch04.h ... 0490379936
2-1. 每次 VirtualBox 升級新版本 都需重新安裝一次

3. 詳細參閱

在vbox里面安装的是windows xp sp2，安装好extension pack和guest addition后，系统果然好用多了。

[montana]

请问一下，除了vim和emacs之外，ubuntu里面还有哪些文本编辑器常用于编程？

请问一下，除了vim和emacs之外，ubuntu里面还有哪些文本编辑器常用于编程？

geany 功能也较为丰富
kde 下可用 kate
还有个私有软件 Sublime Text，价格 $70 http://www.sublimetext.com/
类似 Sublime 的开源软件 Atom - A hackable text editor https://atom.io/
https://web-design-weekly.com/2015/07/3 ... s-sublime/

感谢vickycq兄，安装了Sublime Text 3 build 3083, 试用中。

最近发现了个奇怪的事情，就是我的ubuntu偶尔会假死，鼠标都动不了，每当这时我就只能按电源键关闭、重启系统了。ubuntu中有没有类似windows中ctrl+shift+del调出任务处理器，强制关闭假死任务的方法呢？

[vickycq]

我的ubuntu偶尔会假死，鼠标都动不了，...

大写锁定 / 数字键盘锁定指示灯是否闪烁？
能否切换到 tty1-6？
可能是 kernel panic

我的一台机器使用 Ubuntu 14.04 + Linux 3.13 经常kernel panic，用 debian 一切正常。

ubuntu中有没有类似windows中ctrl+shift+del调出任务处理器，强制关闭假死任务的方法呢？

一般应用程序卡死 可在终端下将其杀死
例如文件管理器 Thunar 假死：

代码： 全选

sudo pkill -9 Thunar

参考

http://askubuntu.com/questions/265996/w ... em-freezes
https://help.ubuntu.com/community/DebuggingSystemCrash

[montana]

是联想l440的垃圾本子，没有大写锁定 / 数字键盘锁定指示灯。ctrl+alt+f6可以进入文字界面，下次遇到这种假死的情况试试sudo pkill好不好使。
从来没装过debian，不知道用起来比起ubuntu如何？再说现在的系统里面安装、修改了太多的东西，从头在来工程量似乎有点大。
