ubuntu 聲音很小音量小聲

解決之道:
打開終端機，輸入：alsamixer

PCMan 沒有遊標問題

deb http://ppa.launchpad.net/fourdollars/pcmanx/ubuntu YOUR_UBUNTU_VERSION_HERE main
deb-src http://ppa.launchpad.net/fourdollars/pcmanx/ubuntu YOUR_UBUNTU_VERSION_HERE main

- 將 /tmp 設到 RamDisk (tmpfs) 的方法

基本上只要打以下指令，就能將 /tmp 綁定到 /dev/shm
mkdir /dev/shm/tmp
chmod 1777 /dev/shm/tmp
sudo mount --bind /dev/shm/tmp /tmp

※ 註：為何是用 mount --bind 綁定，而不是 ln -s 軟連結，原因是 /tmp 目錄，系統不給刪除。

不過每次開機都要打指令才能用，這樣是行不通的，必須讓它開機時自動執行，才會方便。

用文書編輯器，建立 /etc/init.d/ramtmp.sh 內容如下：

#!/bin/sh
# RamDisk tmp
PATH=/sbin:/bin:/usr/bin:/usr/sbin

mkdir -p /dev/shm/tmp
mkdir -p /dev/shm/cache
mount --bind /dev/shm/tmp /tmp
mount --bind /dev/shm/cache /home/shihyu/.cache
chmod 1777 /dev/shm/tmp
chmod 1777 /dev/shm/cache

將此檔改權限為 755，使其可執行

sudo chmod 755 /etc/init.d/ramtmp.sh

在 /etc/rcS.d 中，建立相關軟連結(捷徑)，使其一開機就執行以下指令僅能終端機操作

cd /etc/rcS.d
sudo ln -s ../init.d/ramtmp.sh S50ramtmp.sh

fcitx安裝以前曾安裝過fcitx的話，最好把過去的都清理掉，包括 PPA

sudo apt-get install fcitx
sudo apt-get install im-config
sudo add-apt-repository ppa:fcitx-team/nightly
sudo apt-get update

檢查更新 ,更新完, 再繼續安裝碼表

sudo apt-get install fcitx-table-boshiamy (嘸蝦米）
sudo apt-get install fcitx-table-cangjie-big （倉頡大字集）
sudo apt-get install fcitx-table-zhengma-large （鄭碼大字集）
sudo apt-get install fcitx-table-wubi-large （五筆大字集）
sudo apt-get install fcitx-chewing （新酷音）
sudo apt-get install fcitx-sunpinyin （雙拼）
sudo apt-get install fcitx-table-easy-big （輕鬆大詞庫）
sudo apt-get install fcitx-m17n
sudo apt-get remove ibus

im-config

選fcitx為預設
重開機或登入
在有可輸入中文的框中，按Ctrl+Space，然後用Ctrl+Shift選輸入法輸入，預設的簡繁轉換為Ctrl+Shift+F

ubuntu 13.10 記得清除 Text Entry 裡面快速鍵設定, fcitx 才會有作用 IntelliJ IDEA 13 on Ubuntu Linux 13.10 字型美化看習慣 Mac OS X 的字型，再回到 Ubuntu Linux 桌面總會不習慣。主要的差異是 Font Rendering 的效果，讓 Ubuntu 預設的字型看起來過於銳利。裝上 fontconfig-infinality 即可改善。

sudo add-apt-repository ppa:no1wantdthisname/ppa
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install fontconfig-infinality
sudo bash /etc/fonts/infinality/infctl.sh setstyle

最後一道指令要選擇風格，建議用 2 或 4 這兩種其中一個。

Select a style:
1) debug       3) linux       5) osx2      7) win98
2) infinality  4) osx       6) win7      8) winxp

Install NVIDIA GeForce driver in Ubuntu 14.04 / 13.10 / 13.04 / 12.04 using PPA

To add PPA for Ubuntu 14.04 / 13.10 / 13.04 / 12.10

Ubuntu 14.04 / 13.10 / 13.04 / 12.10 users, Run the following command in the terminal and type the password for the user when prompted.  Others use the Ubuntu-X PPA.

sudo apt-add-repository ppa:xorg-edgers/ppa
To add PPA for Ubuntu 12.04 / 11.10 / 11.04 / 10.04

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates

To Update

sudo apt-get update
Now install the NVIDIA GeForce graphics driver 304.108 in your system, as you install other packages by using apt-get.

To Install

sudo apt-get install nvidia-current nvidia-settings
Above command will install the driver.

Install TeamViewer 9 in Ubuntu 14.04 64bit

sudo dpkg --add-architecture i386
sudo apt-get update
wget http://www.teamviewer.com/download/teamviewer_linux.deb
sudo dpkg -i teamviewer_linux.deb
sudo apt-get install -f

Linux 開機就掛載指定的磁區

Linux 版本：Linux mint debian edition 64bit

 sudo ls -l /dev/disk/by-uuid
查詢要掛載磁區的UUID

編輯　 /etc/fstab  這個檔案，檔案內會有已掛載的資訊．可以照本宣科的作．當然要存檔

 mount -a 　重新掛載磁區

確認掛載結果　 df

重開機後，應該就會自動掛載指定的磁區了．

UUID=1f833a4c-b564-4616-bc72-0fc92d62a687 /media/HD         ext4    defaults        0       2

Gitbook 安裝

安裝 Node.js

sudo apt-get update
sudo apt-get install nodejs
sudo apt-get install npm

使用 Global 安裝 gitbook

sudo npm install gitbook -g

如果遇到：

Error loading version latest: Error: Cannot find module 'internal/util/types'

將node版本降低:

// 1.安裝node管理 n
sudo npm install -g n 
// 2. 降低版本，更新npm
sudo n 6

sudo npm install npm -g
// 3.此時運行gitbook2.6.7的命令即可。
gitbook build --gitbook=2.6.7
// 4. 待轉換完成後，將npm版本（例如9.10.0）切回來即可,以免影響其他模塊
sudo n 9.10.0

下載最近版本的npm , 目前可以解決下面說的情況

http://nodejs.org/dist/

安裝 nodejs-legacy 避免後續執行 gitbook 的時後發生錯誤 "/usr/bin/env: node: No such file or directory"

sudo apt-get install nodejs-legacy

安裝 Calibre Tools 以便進行輸出電子書檔案如果未安裝即執行 gitbook pdf 等輸出電子書檔案時會出現錯誤 "Need to install ebook-convert from Calibre"，因此需要先行安裝 Calibre 以便進行後續的輸出動作

sudo apt-get install Calibre

當執行 gitbook pdf -v 出現 "RuntimeError: X server required. If you are running on a headless machine, use xvfb"，所以也需要先安裝 xvfb 避免錯誤

sudo apt-get install xvfb
updatedb

安裝gitbook-editor

下載GITBOOK EDTOR

https://github.com/GitbookIO/editor-legacy/releases
wget https://github.com/GitbookIO/editor-legacy/releases/download/1.1.0/gitbook-linux64.tar.gz

解壓及安裝

tar -xvzf gitbook-linux64.tar.gz
cd linux64
sudo ln -s /lib/x86_64-linux-gnu/libudev.so.1 /lib/x86_64-linux-gnu/libudev.so.0
bash ./install.sh

多個 SSH Key 對應多個 Github 帳號

產生個別的 ssh keys

$ cd ~/.ssh
$ ssh-keygen -t rsa -C "account1@email.com" -f id_rsa_account1
$ ssh-keygen -t rsa -C "account2@email.com" -f id_rsa_account2

github setting Deploy keys

勾選
Allow write access
Can this key be used to push to this repository? Deploy keys always have pull access.

建立 config 檔

$ cd ~/.ssh
$ touch config
$ gedit config

編輯內容如下

#account1
Host github.com-account1
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_rsa_account1

#account2
Host github.com-account2
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_rsa_account2

修改相對應 repo 的 remote url。例如：
- ssh://git@github.com-account1/github account/repo1.git
- github account 是github帳號 ex : jasonblog , ccccjason , shihyu

$ cd /path/to/repo1
$ git remote set-url origin ssh://git@github.com-account1/account1/repo1.git

~/.ssh/config

#account1
Host github.com-ccccjason
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_ccccjason

git remote set-url origin ssh://git@github.com-ccccjason/ccccjason/book.git _book

git clone  ssh://git@github.com-ccccjason/ccccjason/book.git _book

##解決Ubuntu 16.04下提示boot分區空間不足的辦法

最近看瞭看/boot的大小，發現幾次升級後，大小不足，所以想擴容，一開始還想用磁盤操作，但上網查詢後發現，磁盤操作實在風險太大，特別是雙系統的Linux，操作又是很麻煩，後來發現可以刪除多餘的舊內核來清理/boot，釋放空間。下面來看看詳細的解決方法吧。

###前言

因為linux內核一直在更新，更新後，舊的內核就不在使用，但舊的內核文件還在boot裡面，佔據著空間，更新幾次過後boot分區就會被佔滿，顯示boot磁盤空間不足。

###解決辦法

將不用的內核文件刪除，釋放空間。

###步驟如下

一、查看已安裝的內核 dpkg --get-selections |grep linux-image

dpkg --get-selections |grep linux-image
linux-image-4.4.0-21-generic deinstall
linux-image-4.4.0-57-generic install
linux-image-4.4.0-59-generic install
linux-image-4.4.0-62-generic install
linux-image-4.4.0-64-generic install
linux-image-extra-4.4.0-21-generic deinstall
linux-image-extra-4.4.0-57-generic install
linux-image-extra-4.4.0-59-generic install
linux-image-extra-4.4.0-62-generic install
linux-image-extra-4.4.0-64-generic install
linux-image-extra-virtual install
linux-image-generic install

後面帶deinstall的為已刪除的內核，可以忽略

二、使用uname -a查看自己當前啟動的是哪個內核

uname -a
Linux eason 4.4.0-62-generic #83-Ubuntu SMP Wed Jan 18 14:10:15 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

從輸出可知我們當前啟動的內核是4.4.0-62-generic

三、運行apt-get remove命令卸載其他內核，為瞭保險起見，保留最近的一兩個版本。

sudo apt-get remove linux-image-4.4.0-57-generic
sudo apt-get remove linux-image-4.4.0-59-generic
sudo apt-get remove linux-image-extra-4.4.0-57-generic
sudo apt-get remove linux-image-extra-4.4.0-59-generic

如提示有未卸載幹凈的可以執行sudo apt-get remove來卸載。

使用 sudp dpkg -P 可以乾淨移除

sudp dpkg -P linux-image-4.4.0-57-generic
