系统配置

摘要

多年来,具体来说5年了,我一直使用ub+awesome的工作环境。在过程中,被公司的同事 笑成为”生活在CUI”中的另类。我选中ub是因为方便,apt-get实在让我无法自拔,并且ub 对于desktop的支持也是很多别的linux发行版无法比拟的。cos等等都比较适合部署在 server环境上。选中awesome,是因为喜欢它简洁的界面,瓦片式的管理也让屏幕的任何 一部分都不会被浪费。再加上我本身就喜欢CUI,所以awesome就成了首选。这些年来,积 累了一些配置文件,个人觉得还算用着顺手,这里就拿出来分享一下。

awesome

  1. 声音。
    ub的root默认是不开的,我又不喜欢使用sudo,就是不喜欢那种隔一层纱的感觉,所以虽 然自知linux不推荐开启root,但是我还是喜欢使用root的直接。所以一般我第一件事情 就是把root开启。开启的root的命令是:
    sudo pwsswd root
    

    然后输入你的root密码,这样就算是打开了,但是还不能登陆。还需要更改登陆配置。找 到/etc/gdm/gdm.conf,然后把AllowRoot改为true。
    如果你的root账户还不能登陆,你还需要去”系统->系统管理->登陆窗口”中的安全页中把 “允许本地系统管理员登陆”选项打开。

  2. 声音。
    root登陆后,你会发现声音没了。对我这种上班就带上耳机的人来说这是相当不能接受的 。所以你也要把声音打开。找到pulseaudio文件,然后把文件内的两个选项改成以下这样:
    PULSEAUDIO_SYSTEM_START=1
    DISALLOW_MODULE_LOADING=0
    

    重启,就会有声音了。但是还有一个问题就是不知道为什么,有的时候启动的时候也是没 有声音,但是重启一下就正常了,分析了一下日志也没发现有什么问题,如果你知道,请 你告诉我。

  3. chrome在root下无法启动。
    ub的root环境下,chrome无法启动,所以必须得给它加一个脚本,自定义user-data-dir 参数,就可以了。
    # /bin/bash
    google-chrome \-\-user-data-dir=/root/.config/google-chrome &
    
  4. awesome
    安装awesome
    apt-get install awesome
    

    awesome在/etc/下有一个文件夹是有它的配置文件的,awesome的配置文件使用lua写的, 个人的配置文件如下:

    -- Standard awesome library
    require("awful")
    require("awful.autofocus")
    require("awful.rules")
    -- Theme handling library
    require("beautiful")

    terminal = "x-terminal-emulator"
    editor = os.getenv("EDITOR") or "editor"
    editor_cmd = terminal .. " -e " .. editor

    -- Default modkey.
    -- Usually, Mod4 is the key with a logo between Control and Alt.
    -- If you do not like this or do not have such a key,
    -- I suggest you to remap Mod4 to another key using xmodmap or other tools.
    -- However, you can use another modifier like Mod1, but it may interact with others.

</br> 在使用awesome的过程中,需要dmenu加以配合,这样你的CUI才能真正的用起来,算起来 。

  1. 关机
    关机需要xlockmore和xautolock两个软件进行配合,使用apt-get就可以。
    xlockmore是锁屏和关机的,xautolock是自动启动屏保啥的。
    然后在增加一个shutdown的bash文件,你就可以使用这个文件来关机或者休眠了。
#! /bin/sh

  1. 小红点
    因为一直使用Thinkpad的笔记本,但是ub对于小红点的支持貌似不是太好,刚刚开始的几 个ub的版本好像还不支持小红点,所以就使用一个第三方的软件来加以支持,这个软件叫 gpointing-device-settings,安装以后还是相当好用的,但是你还需要加一个配置文件。 当然,后来的ub好像已经开始支持小红点了,具体忘了,很久没用Thinkpad了。

  1. CUI中文件夹的颜色
    当你使用CUI的时候,使用ls列出来的文件和文件夹都是一样的颜色,你也不能很好的辨 认出来,所以,你增加一个dircolors文件,并且做一个软连接到这个文件就可以:

\# Below are the color init strings for the basic file types. A color init
\# string consists of one or more of the following numeric codes:
\# Attribute codes:
\# 00=none 01=bold 04=underscore 05=blink 07=reverse 08=concealed
\# Text color codes:
\# 30=black 31=red 32=green 33=yellow 34=blue 35=magenta 36=cyan 37=white
\# Background color codes:
\# 40=black 41=red 42=green 43=yellow 44=blue 45=magenta 46=cyan 47=white
\#NORMAL 00 # no color code at all
\#FILE 00 # regular file: use no color at all
RESET 0 # reset to "normal" color
DIR 01;34 # directory
LINK 01;36 # symbolic link. (If you set this to 'target' instead of a
\# numerical value, the color is as for the file pointed to.)
MULTIHARDLINK 00 # regular file with more than one link
FIFO 40;33 # pipe
SOCK 01;35 # socket
DOOR 01;35 # door
BLK 40;33;01 # block device driver
CHR 40;33;01 # character device driver
ORPHAN 40;31;01 # symlink to nonexistent file, or non-stat'able file
SETUID 37;41 # file that is setuid (u+s)
SETGID 30;43 # file that is setgid (g+s)
CAPABILITY 30;41 # file with capability
STICKY_OTHER_WRITABLE 01;34 # dir that is sticky and other-writable (+t,o+w)
OTHER_WRITABLE 01;34 # dir that is other-writable (o+w) and not sticky
STICKY 01;34 # dir with the sticky bit set (+t) and not other-writable
\# This is for files with execute permission:
EXEC 01;32
\# List any file extensions like '.gz' or '.tar' that you would like ls
\# to colorize below. Put the extension, a space, and the color init string.
\# (and any comments you want to add after a '#')
\# If you use DOS-style suffixes, you may want to uncomment the following:
\#.cmd 01;32 # executables (bright green)
\#.exe 01;32
\#.com 01;32
\#.btm 01;32
\#.bat 01;32
\# Or if you want to colorize scripts even if they do not have the
\# executable bit actually set.
\#.sh 01;32
\#.csh 01;32

  1. 外接投影仪或者显示器 外接显示器或者投影器,你必须使用xrand来支持。开机的时候awesome好像默认会检测你 的屏幕数量然后加以显示。如果没有自动,那么你只需要运行一下一下的代码就可以了。
\#/usr/bin/env bash

结束语

这些配置文件都是可以直接拿来用的,我已经经过了测试。保证可以使用。
因为现在也不太用ub+awesome了,改用了mac,但是说实话,mac没有ub+awesome好用和自 如。如果还能选择,我想还是ub+awesome来的更适合我一些。
