apt $APT_OPTS remove --purge $PURGE替换 Firefox 为国内版 #
火狐自 Quantum 之后的版本在 Linux 上的体验都很棒，火狐通行证的同步也很方便，不过 Ubuntu 自带的火狐是国际版本，个人感觉不如国内版的同步速度快，所以就研究了下替换国内版的操作。
1. 下载国内版火狐 #
via: Firefox-latest-x86_64.tar.bz2
2. 重命名系统自带 #
sudo mv /usr/lib/firefox /usr/lib/firefox.bak
3. 解压下载的文件放到/usr/lib/firefox #
sudo cp firefox /usr/lib/
4. 复制原 Firefox 启动脚本 #
sudo cp /usr/lib/firefox.bak/firefox.sh /usr/lib/firefox
5. 复制原 dictionaries 软链接[可不做] #
sudo cp /usr/lib/firefox.bak/dictionaries /usr/lib/firefox
6. 删除原默认配置文件 #
rm -rf ~/.mozilla
安装一些版权受限的软件 #
sudo apt-get install ubuntu-restricted-extras换个趁手的oh-my-zsh #
http://ohmyz.sh/
sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
右键添加打开终端的选项
#
打开终端的选项sudo apt-get install nautilus-open-terminal
似乎15.04开始这个package自带了～
某些应用indicator图标无法正常显示问题
#
sudo apt-get install python-appindicator
更改Chromium浏览器缓存到/tmp #
sudo vi /etc/chromium-browser/default
改路径到/tmp
# Default settings for chromium-browser. This file is sourced by /bin/sh from
# /usr/bin/chromium-browser
# Options to pass to chromium-browser
CHROMIUM_FLAGS="--disk-cache-dir=/tmp/Chromium/"收工～啥？还在用火狐？启动那么慢能忍受么。。。
利用tmpfs文件系统（要求RAM>4G）
#
sudo vi /etc/fstab
新起一行，写入以下内容
# temporary directories
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
tmpfs /var/tmp tmpfs defaults,noatime,mode=1777 0 0
tmpfs /var/spool tmpfs defaults,noatime,mode=1777 0 0
# log directories
tmpfs /var/log tmpfs defaults,noatime,mode=0755 0 0 调swappiness值
#
关于swap的介绍，挺详细
https://help.ubuntu.com/community/SwapFaq
我机器内存够大，所以基本上是不分swap分区的
sudo gedit /etc/sysctl.conf
Search for vm.swappiness and change its value as desired. If vm.swappiness does not exist, add it to the end of the file like so:
vm.swappiness=10
内存如果够大，这里完全可以设为0，或者干脆干掉swap分区，机智如我～
关于磁盘分区格式的选择 #
- 我只分三个
/efi fat16 # 100MB左右足够、/ ext4 # 20GB左右和/home ext4 #剩余空间全给，如果是SSD，格式换为btrfs - 要不要swap分区？我的选择是不要，因为物理内存足够大，就算不够用，可以随时用swapfile启用，用完再删即可
截图工具的选择 #
我比较喜欢用深度截图工具，简单好用 deepin-scrot_2.0-0deepin_all.deb
sudo dpkg -i deepin-scrot_2.0-0deepin_all.deb
sudo apt-get -f install然后设定快捷键呼出ctrl+alt+A
system-settings --> keyboard --> custom shortcuts添加command deepin-scrot %u绑定ctrl+alt+A
禁用系统bug报告弹窗 #
bug报告本来是好事，但无奈弹的太多了些，多数情况除了影响心情外，并没有什么卵用，所以需要禁用之：
sudo vi /etc/default/apport
# set this to 0 to disable apport, or to 1 to enable it
# you can temporarily override this with
# sudo service apport start force_start=1
enabled=0更改普通用户密码为简单密码 #
系统默认策略不允许普通用户设定简单密码，所以如果想要设定简单密码的话，可以先切到root然后再换
sudo -i
passwd uersname安装deb二进制包
#
可以简单的双击安装， 或者命令行
sudo dpkg -i xxx.deb
sudo apt-get -f install百度网盘bcloud
