又把Ubuntu玩壞了，很多設定都要從寫，先來個紀錄。

製作開機USB

[ref]

dd bs=4M if=/path/to/ubuntu.iso of=/dev/sdx && sync

備份package list

備份PPA list

[ref]

grep -RoPish '(?<=ppa.launchpad.net/)[^/]+/[^/ ]+' /etc/apt | sort -u | sed 's/^/ppa:/'

# This script generate sth. like this:

# ppa:ubuntu-wine/ppa
# ppa:am-monkeyd/nautilus-elementary-ppa
# ppa:nilarimogard/webupd8
# ppa:ubuntu-x-swat/x-updates
# ppa:tualatrix/ppa
# ppa:banshee-team/banshee-unstable
# ppa:chromium-daily/beta
# ppa:libreoffice/ppa
# ppa:banshee-team/ppa

然後在重新安完ubuntu後，可以利用~/ppa-backup.txt xargs -I % sudo add-apt-repository %加回PPA。

urxvt

correct copy to system clipboard and paste to system clipboard
change sh to bash

i3-wm

i3blocks

[[github(https://github.com/vivien/i3blocks)]]
Ubuntu只有在15.04之後才有把i3blocks納入official repository，14.04LTS只能手動從github下載安裝。

git clone git://github.com/vivien/i3blocks
cd i3blocks
make clean debug # or make clean all
# make install

另外i3blocks依賴ronn utility，須安裝ruby-ronn package。

安裝中文字體

$ sudo apt-get install ttf-wqy-*

利用fstab在開機自動掛載硬碟

• sudo fdisk -l:列出指定裝置的partition tables，若不指定裝置則是印出/proc/partions中的內容

  WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.
  
  
  Disk /dev/sda: 128.0 GB, 128035676160 bytes
  255 heads, 63 sectors/track, 15566 cylinders, total 250069680 sectors
  Units = sectors of 1 * 512 = 512 bytes

• sudo blkid: locate/print block device attributes

  /dev/sda2: UUID="40a6134a-199b-4d5a-aaf9-ab331706e03a" TYPE="ext4" 
  /dev/sda3: UUID="04cf23d4-045c-4c72-92ca-e4069889599d" TYPE="ext4" 
  /dev/sda4: UUID="2b2e2214-831d-456e-b9ed-203077920dae" TYPE="swap" 
  /dev/sdb1: UUID="e3ebb57a-58ef-4779-9721-3662b0f2f548" TYPE="ext4"

最終的/etc/fstab為：

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda3 during installation
UUID=04cf23d4-045c-4c72-92ca-e4069889599d /                  ext4    errors=remount-ro 0       1
# /home was on /dev/sda2 during installation
UUID=40a6134a-199b-4d5a-aaf9-ab331706e03a /home              ext4    defaults          0       2
# swap was on /dev/sda4 during installation
UUID=3b2e2214-831d-456e-b9ed-203077920dae none               swap    sw                0       0
UUID=e3ebb57a-58ef-4779-9721-3662b0f2f548 /media/jordan/MASS ext4 	 defaults          0       0

最後，執行sudo mount -a，掛載所有在fstab中指定的檔案系統。

網路設定

/etc/network/interfaces
auto interface – Start the interface(s) at boot. That’s why the lo interface uses this kind of linking configuration.
allow-auto interface – Same as auto
