安装Ubuntu 15.04之后

前言

重装了系统, 不小心点错了键盘, 用户名设置错了, 再折腾一下其他东西又是一晚上, 幸亏以前用过Ubuntu, 还有点印象，重装前Kali也算是和Ubuntu同源的，都来自Debian，所以没有走太多弯路。

2. Flash

cp libflashplayer.so /usr/lib/mozilla/plugins/

3. Input Method

先apt-get install fcitx-table-wbpy, 再在Language Support里改框架为fcitx，修改配置重启

4. Desktop

修改一下桌面背景、透明度、终端配色等

5. hostname username

对于hostname

首先修改 /etc/hostname文件
sudo vim /etc/hostname
将其中的主机名改为你所要修改的主机名
再修改 /etc/hosts文件
sudo vim /etc/hosts
127.0.0.1 主机名
这里的主机名要和上面修改的一致
修改完成后需重启

对于username

先切换到tty终端下，如tty1为Ctrl+Alt+F1
chfn hypocisy
usermod -l hypocrisy hypocisy
usermod -d /home/hypocrisy/ -m /home/hypocisy/
groupmod -n hypocrisy hypocisy
实际信息可以看/etc/passwd和/etc/shadow

6. Default root

修改lightdm配置对于早期的系统，打开root登陆，修改 /etc/lightdm/lightdm.conf.d/50-unity-greeter.conf 添加：greeter-show-manual-login=true allow-guest=true 说明：greeter-show-manual-login=true #允许手工输入登陆系统的用户名和密码 allow-guest=true #允许guest登录，可以根据自己的需要修改保存后重启，就可以通过输入用户名root登陆了而在15.04中，配置文件位置改变了，为 /user/share/lightdm/lightdm.conf.d/ 加入greeter-show-manual-login=true 之后重启会有错误，再修改/root/.profile tty -s && mesg n

7. Proxy

Shadowsocks

8. root后的问题

root登录后发现他把键有些不能补全，修改/root/.bashrc文件

#if [ -f /etc/bash_completion ] && ! shopt -oq posix; then
#    . /etc/bash_completion
#fi

将上述注释去了即可
root后无声音：修改/root/.profile，最后加一句
pulseaudio --start --log-target=syslog

或者运行alsamixer，修改auto-mute-mode

9. Github

https://help.github.com/articles/generating-ssh-keys/
创建ssh key先，ls -al ~/.ssh查询该主机没有ssh key，于是创建：
ssh-keygen -t rsa -b 4096 -C "[email protected]"
Ensure ssh-agent is enabled:
eval "$(ssh-agent -s)"
Add your SSH key to the ssh-agent:
ssh-add ~/.ssh/id_rsa

open the ~/.ssh/id_rsa.pub file.
Select the entire contents of the file and copy it to your clipboard. Do not add any newlines or whitespace.
Add the copied key to GitHub:

Test the connection:
ssh -T [email protected]
