回到監獄般的實驗室，用一臺4年前的廢電腦，裝一個ubuntu來玩玩吧。

問題1 ubuntu 14.04 –系統的網路服務與此版本的網路管理器不相容問題
1、sudo -s
2、cd /etc/NetworkManager/
3、ls -la
4、mv system-connections /home// #移動目錄到自己的使用者目錄下
5、mkdir /system-connections
6、reboot
當然，也可能是！32位的老機器，下載了64位的系統~~
問題2 銳捷上網問題
校園網下載客戶端後，
cd rjsupplicant
sudo ./rjsupplicant.sh -d 0 -u username -p password
此時如果網絡卡消失了
cd /etc/init.d/
sudo start network-manager
問題3 搭建ssh伺服器
sudo apt-get update
sudo apt-get install openssh-server
問題4 vim tab設定為四個空格
vim ~/.vimrc新增以下內容
set ts=4
set expandtab
問題5 安裝java
以安裝 jdk-8u72-linux-x64.tar.gz 為例
#解壓安裝包：
sudo tar -zxvf jdk-8u72-linux-x64.tar.gz
mv jdk1.8.0_72/ /opt/
#配置環境變數：
#編輯配置檔案：
sudo vim /etc/profile
#在該檔案的最尾巴，新增下麵內容：
JAVA_HOME=/opt/jdk1.8.0_72
JRE_HOME=$JAVA_HOME/jre
PATH=$PATH:$JAVA_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME
export JRE_HOME
export PATH
export CLASSPATH
#執行命令，掃清該配置（必備操作）：
. /etc/profile
#檢查是否使用了最新的 JDK：
java -version
安裝maven
下載解壓完後， vi~/.zshrc
export M2_HOME=/opt/software/apache-maven-3.5.0
export M2=$M2_HOME/bin
export PATH=$M2:$PATH
sublime中文輸入問題
解決方法：
#1. 進入sublime text3 外掛管理檔案夾
cd ~/.config/sublime-text-3/Packages
#2. 獲取InputHelper外掛
git clone https://github.com/xgenvn/InputHelper.git
#如果發現在sublime text3 中無法使用ctrl+shift+z調出輸入框，請檢查是否安裝pygtk
sudo apt-get install python-gtk2-dev
grub>
想給實驗室的這臺小電腦挖坑，就保持
linux (hd0,1)/vmlinuz.efi root=/dev/sda3
initrd (hd0,1)/initrd.lz
boot
不然就試試
sudo update-grub
sudo grub-install /dev/sda
好用軟體系列

自己從廢舊電腦裡淘到一個i5-3代的cpu，從一堆2G的記憶體裡淘到兩個4G的，現在牛氣哄哄地升級系統，之前真的是，一把心酸淚
升級17.04
配置apt源，校園網，用清華的吧
sudo vi/etc/apt/sources.list

升級！

升級17.04後沒有聲音
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).

安裝系統監控indicator-sysmonitor
sudo add-apt-repository ppa:fossfreedom/indicator-sysmonitor
sudo apt-get update
sudo apt-get install indicator-sysmonitor
最後在終端執行indicator-sysmonitor &即可
安裝zsh
之前竟然沒有放進來,裝oh my zsh的前提是要裝好了curl以及git
sudo apt-get install curl
sudo apt-get install git
sudo apt-get install zsh
sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
