服务器评测
买沙发的时候首要考虑的是尺寸（能放下不、能躺的直不），其次才是质量、牌子、观感……，功能是首要的，扩展功能也是必须的，我就会把各种大小、厚薄、的靠枕、抱枕在沙发上堆成一个窝然后躺在里面看书。因为常躺于是自己做（自己选材，自己剪裁，自己制作）了两套沙发套，便于换洗。现今电脑可能是仅次于手机的高频使用的信息媒介（对于我来说书比手机频率高）了，怎么用，用的爽不爽只有自己知道，习惯、品味……等各种因素掺杂其间。裸机装完操作系统，多少会做些设置——安装喜欢的软件、加快捷方式、设壁纸、设屏保……。
用Elementary OS freya半年了，各种日常遇到的问题解决后，发现做个简单的总结很有必要（有些解决方法快忘了）。
在Elementary OS 0.3下用WPS http://www.linuxidc.com/Linux/2014-11/109976.htm
1、关闭lightdm的访客会话
方法不止一个，我个人倾向于这个方案显得更干净，从askUbuntu上看到的。
sudo sh -c ‘printf “[SeatDefaults]nallow-guest=falsen” >/usr/share/lightdm/lightdm.conf.d/50-no-guest.conf’
2、plank设置
就是那个docker了，宽屏显示器下应该有不少人会把启动器放在边上，我就放在左边（不管Linux还是Windows，不管Unity还是Plank）我也看到过有人用MAC也把dock放左边。如果不喜欢缺省的GTK主题可以考虑缺省安装的三个主题，我喜欢透明的（尽管缺省的那个主题功能性更好），如果爱折腾还有第三方的主题可用。
主题就放在/usr/share/plank/theme下，目录名就是主题名。主题设置以前是可以在系统设置中设置的，后面升级后设置界面没了。可以手工修改配置文件。
#The position for the dock on the monitor. If 0, left. If 1, right. If 2, top. If 3, bottom.
Position=0
#The name of the dock’s theme to use.
Theme=Transparent
3、热区设置
这是我觉得gnome应该有的功能（KDE里好像也有），我通常会设定两个下角热区。
4、完成完整语言包的安装
安装时在启动菜单出来前选择中文，安装过程中会显示下载语言包，但结果还是不完整。在系统设置中”区域和语言“部分可以根据提示完成语言支持的安装。但有时翻译还是不够完整，我的方法是卸载language-pack-gnome-zh-hans再安装。
sudo apt-get remove language-pack-gnome-zh-hans
sudo apt-get install language-pack-gnome-zh-hans
顺便提一下：
如果从beta2镜像安装，托盘上有可能看不到输入法指示器，也呼不出输入法。运行ibus-setup设置一下就可以输入了，指示器不一定会出来。
”区域和语言“中那个“应用于登陆窗口、访客账户及新用户”不要点，如果不慎点了，恢复/etc/default下的keyboard和locale即可。
5、安装惯用软件——浏览器、编辑器等
我是重度浏览器用户所以不用系统的缺省浏览器，用firefox还是chromium看个人喜好和需求，我依赖ff的一些插件且有打开60个以上标签页的习惯，所以使用firefox并将”启动Firefox时(S)“设置成”显示上次打开的窗口和标签页“
sudo apt-get install firefox firefox-locale-zh-hans
sudo apt-get install chromium-browser chromium-browser-l10n
最近系统升级后firefox地址栏中输入中文会有奇怪的现象（比如用鼠标选择地址栏中内容时成了删除这些内容）甚至导致firefox僵死，解决办法是在地址栏输入时切换到非拼音（pinyin）输入法比如sunpinyin或英文。后来决定反正要用sublime text所以安装搜狗拼音。安装方法可参考：
系统没带office软件，如果有需要安装wps也不错。安装方法可参考：在elementary OS 0.3下用WPS
缺省编辑器scratch支持utf8中文，但输入不了中文，没细研究反正要写些代码就安装了sublime text 3
sublime text 中文输入参考了官方论坛的方法

sublime-imfix.c
Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.
By Cjacker Huang
By whitequark@whitequark.org
How to compile:
gcc -shared -o libsublime-imfix.so sublime_imfix.c `pkg-config –libs –cflags gtk+-2.0` -fPIC
How to use:
LD_PRELOAD=./libsublime-imfix.so sublime_text
Changes:
2014 06-09
1, Fix cursor position update for sublime text 3.
2, Combine the codes from whitequark(fix for xim immodule) and add cursor update support for XIM immodule.
