回到监狱般的实验室，用一台4年前的废电脑，装一个ubuntu来玩玩吧。

问题1 ubuntu 14.04 –系统的网络服务与此版本的网络管理器不兼容问题
1
、sudo -s
2
、cd /etc/
NetworkManager
/
3
、ls -la
4
、mv system-connections /home//
移动目录到自己的用户目录下
5
、mkdir /system-connections
6
、reboot
当然，也可能是！32位的老机器，下载了64位的系统~~
问题2 锐捷上网问题
校园网下载客户端后，
cd rjsupplicant
sudo ./rjsupplicant.sh -d
0
-u username -p password
此时如果网卡消失了
cd /etc/init.d/
sudo start network-manager
问题3 搭建ssh服务器
sudo apt-
get
update
sudo apt-
get
install openssh-server
问题4 vim tab设置为四个空格
vim ~/.vimrc添加以下内容
set
ts=
4
set
expandtab
问题5 安装java
以安装 jdk-8u72-linux-x64.tar.gz 为例
解压安装包：
sudo tar -zxvf jdk-
8u72
-linux-x64.tar.gz
mv jdk1.
8.0
_72
/ /
opt/
配置环境变量：
编辑配置文件：
sudo vim /etc/profile
在该文件的最尾巴，添加下面内容：
JAVA_HOME=
/opt/
jdk1.
8.0
_72
JRE_HOME=$JAVA_HOME/jre
PATH= JAVA_HOME/bin
CLASSPATH=.: JAVA_HOME/lib/tools.jar
export
JAVA_HOME
export
JRE_HOME
export
PATH
export
CLASSPATH
执行命令，刷新该配置（必备操作）：
. /etc/profile
检查是否使用了最新的 JDK：
java -version
安装maven
下载解压完后， vi~/.zshrc
export
M2_HOME=
/opt/
software/apache-maven-
3.5
.
0
export
M2=$M2_HOME/bin
export
PATH=
PATH
sublime中文输入问题
解决方法：
1. 进入sublime text3 插件管理文件夹
cd ~
/.config/
sublime-text-
3
/
Packages
2. 获取InputHelper插件
git clone https:
//github.com/xgenvn/InputHelper.git
如果发现在sublime text3 中无法使用ctrl+shift+z调出输入框，请检查是否安装pygtk
sudo apt-
get
install python-gtk2-dev
grub>
想给实验室的这台小电脑挖坑，就保持
linux (hd0,
1
)/vmlinuz.efi root=
/dev/
sda3
initrd (hd0,
1
)/initrd.lz
boot
不然就试试
sudo update-grub
sudo grub-install /dev/sda
好用软件系列

自己从废旧电脑里淘到一个i5-3代的cpu，从一堆2G的内存里淘到两个4G的，现在牛气哄哄地升级系统，之前真的是，一把心酸泪
升级17.04
配置apt源，校园网，用清华的吧
sudo vi/etc/apt/sources.list
默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释

升级17.04后没有声音
NVidia
The first step is to make sure that the GPU is not in use by a driver. As you’re using the nvidia driver, you must also be using prime.Run prime-select query.If it outputs nvidia, you can disable the driver by running sudo prime-select intel and rebooting.If it outputs unknown then the previous step might also work, but will also break your bumblebee setup.As a sanity check, make sure that the GPU and its audio chip are powered:Login as root: sudo suRun lspci -H1 | grep 01:00. It should output two lines.If the first line ends with (rev ff), you need to power your GPU by running echo ON > /proc/acpi/bbswitch.If the second line is missing, that means that the GPU audio chip is no longer powered. You can try suspending your laptop; resume it again; and check again whether the GPU audio chip is powered (I hope that works for you, otherwise you’re out of luck, like me).Run lsmod | grep nvidia again to make sure that the nvidia driver is still not in use.Now that the GPU is powered without a driver we’re going to ‘remove’ it:Run echo 1 > /sys/bus/pci/devices/0000:01:00.0/remove (if the GPU still had a driver loaded/in use, this causes a kernel panic).Redetect the GPU and also its audio chip by running echo 1 > /sys/bus/pci/rescan.Run lspci | grep 01:00.1. If that outputs anything, congratulations! Your linux is now aware of your GPU audio chip.Get X running with the nvidia GPU.Run prime-select. If it outputs intel, run prime-select nvidia.Logout and back in again.If you run aplay -l now it should output the HDMI outputs (on my pc there are 4 outputs, and only 1 works).

安装系统监控indicator-sysmonitor
sudo add-apt-repository ppa:fossfreedom/indicator-sysmonitor

最后在终端执行indicator-sysmonitor &即可

之前竟然没有放进来,装oh my zsh的前提是要装好了curl以及git
sudo apt-
get
install curl
sudo apt-
get
install git
sudo apt-
