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)。
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。
原文链接
sudo sh -c 'printf "[SeatDefaults]nallow-guest=false\n" >/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(~/.config/plank/dock1/settings)。
#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。
如果在”区域和语言“中指定了输入法(勾选),且输入法是缺省的ibus的话,输入法指示器就消失。而不指定则在进入“键盘”设置是会宕出去。
”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:elementary os Freya Beta 2 发布了!
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
系统自带的视频播放器audience挺不错,我到目前还没想去装mpv。
缺省编辑器scratch支持utf8中文,但输入不了中文,官方Bug报告里有讨论如下方法:GTK_IM_MODULE=xim scratch-text-editor 经验证fcitx、ibus下都可用(只是ibus不光标跟随),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中的方法

6、系统设置中键盘设置crash的问题
其实挺简单,在”区域和语言“中设置勾选”键盘输入“—— ”汉语“即可(单这样会导致键盘指示器消失)。如果你喜欢键控或查看有哪些快捷键可用的话。
