My Ubuntu Setting

Ubuntu 10.10

Install Japanese Ubuntu 10.10

I used Japanese Ubuntu installation CD-ROM instead of the English one. With the English version CD-ROM, the installation stopped when I selected Japanese keyboard. Furthermore, I need Japanese environment applications such as Anthy, IBUS, to be installed by default.

However, under the home directory, directories with Japanese name are created. I changed these directories' name using Nautilus (Windows' Explorer-like application) by pressing F2 (just like in Windows). I left the デスクトップ directory name as it is. Lastly, confirm that the new directory names are correctly updated in ~/.config/user-dirs.dirs.

Customizing Japanese Keyboard Layout

First thing to do, swap Ctrl and CapsLock key. See below page:

https://forums.ubuntulinux.jp/viewtopic.php?id=4432

System -> Preferences -> Keyboard
Go to the "Layout Options" tab
Go through the options for "Ctrl key position" and "Caps Lock key behaviour"

Next, remap 無変換 (Muhenkan) and 全候補変換 (Zen-kouho-henkan) to Control_L and Control_R, respectively.

Refer to below pages. Here, we need to use "xev" to check the keycode of 無変換 (Muhenkan) and 全候補変換 (Zen-kouho-henkan).

Windows-key (<Super>) Global Keyboard Shortcuts

Bind combinations using Windows-key to launch applications. Below described method is for METACITY (GNOME2 default window-manager) only. (Make sure that システム > 設定 > 外観の設定 > 視覚効果 is set to 効果なし)

Launch gconf-editor.
Navigate to "apps | metacity | keybinding_commands". Once there in the righthand pane select "command_1" and change the value to /usr/bin/emacs.
Now we need to define the shortcut which will execute it, we do that by visiting the key "apps | metacity | global_keybindings". Choose "run_command_1" and set the value to be "<Control><Alt>e".
Do for "Win key <Super> + e -> nautilus" (Set as <Super>e), "Win key <Super> + t -> gnome-terminal", and "Win key <Super> + f -> firefox".

Refer to http://www.debian-administration.org/article/611/Creating_global_keyboard_shortcuts_in_GNOME.

For nautilus, there is a method to launch it without using the above method:

Go to System > Preferences > Keyboard Shortcuts.
Then make a shortcut for "Home folder". That will launch nautilus in your home folder, which is basically the same as launching Nautilus only.

FYI:

"Windows-key + r" run-command is "Alt + F2" in Ubuntu
Toggle maximize/ordinary window: "Alt + F10"

In Unity, the launcher is bound to Super-key. So, we must first bind the launcher to Super+l (small L) for example, to freed the Super key. Then bind Super+E to nautilus for example.

See this to unbind launcher from Super key: http://askubuntu.com/questions/34145/can-i-define-keyboard-shortcuts-using-the-super-key

Emacs key-binding in GNOME

Set the gtk-key-theme to activate Emacs keybinding in GNOME as in below page:

https://wiki.ubuntulinux.jp/UbuntuTips/Desktop/GnomeEmacsKeyTheme

A detailed explanation for Firefox is available below:

http://kb.mozillazine.org/Emacs_Keybindings_(Firefox)

So, basically, do:

Alt+F2 -> gconf-editor -> /desktop/gnome/interface/gtk_key_theme Emacs
Reboot

If something strange happen (such as, the value of the field cannot be edited), then:

"sudo rm /etc/gconf/gconf.xml.{defaults, mandatory}/%gconf-tree.xml "
Reboot

Also, change the Anthy trigger from Control-Space to Control-o:

設定->キーボードインプットメソッド(IBusの設定)
Change from Ctrl-Space to Ctrl-o

VPN Softwares

Use the bundled VPN and remote-desktop-client. For the VPN setting, in the "Advanced" option, activate all the "Security and Compression". And as remote-desktop-client, use the "ターミナルサーバークライアント" (add to panel), then set "RDPv5" as the protocol.

To connect to L2TP VPN server:

http://bailey.st/blog/2011/07/14/connecting-to-a-l2tpipsec-vpn-from-ubuntu-desktop/

Application Software Installation

Basically, use synaptics-package-manager. By using this, the installed software will be added to the repository (check アプリケーション→Ubuntuソフトウェアセンター OR システム→システム管理→アップデートマネージャ press 設定 then 他のソフトウェア to check that the installed software is really added to the repository), and automatically updated when a new version is available.

Btw, below is the command used to update and upgrade:

% sudo apt-get update && sudo apt-get upgrade

To check the version of package installed (by apt-get install) in Ubuntu:

https://qiita.com/white_aspara25/items/723ae4ebf0bfefe2115c
- dpkg -l | grep libboost
- dpkg -l libboost-all-dev

Also refer to below site:

「アップデートマネージャ」は現在使用してるプログラムの修正アップデートだけではなく、リボジトリを追加することで新しいアプリケーションのインストールを支援する機能も持っています。

May need to install softwares introduced in "9-things-i-did-after-installing-brand-new-Ubuntu-10" and "12-things-i-did-after-installing-new-Ubuntu-11".

Make a Better Nautilus Install nautilus-open-terminal (must reboot then) for bash-here (use Synaptic).

Install nautilus-elementary (use below link).

http://www.techdrivein.com/2010/10/nautilus-elementary-in-ubuntu-maverick.html

http://www.techdrivein.com/2010/05/what-is-nautilus-elementary-and-how-to.html

Some features of nautilus-elementary:

F7 to open terminal embedded in the nautilus-elementary (Not so useful because the keybinds are corrupted. Use nautilus-open-terminal is sufficient)
Open 2 columns as 2 windows to for example compare 2 directories or copy-paste (表示ツールバー → エキストラペイン (Extra pane)) <== Press F3

Install Gloobus preview as file previewer:

http://www.techdrivein.com/2010/08/gloobus-preview-nautilus-elementary.html

You can just browse through your folders by initiating Gloobus Preview with a simple space bar click and then easily go to the next folder/file using arrow keys. Be careful, don't use GTK theme for Gloobus preview. Do not change the default setting of Gloobus preview.

In case that terminal "bash-here" can not be opened from Nautilus, or double-clicking a file does not launch the appropriate application, we may need to do killall nautilus.

To toggle from Breadcrumb to location bar, press Ctrl+L. To go back from location bar to Breadcrumb, press Esc.

Bash

Set bash to be case-insensitive during file-name-completion by adding "set completion-ignore-case on" to /etc/inputrc. Also "set bell-style visible" in /etc/inputrc.

Set appropriate aliases for cp, rm also. My dot.bashrc is available in Setting Files subpage.

Emacs23

My .emacs is available in Setting Files subpage. Using this .emacs, it is possible to use Emacs as an Integrated Development Environment as shown in below screenshot. Notice the "auto-complete" of instance variable in action.

Need to copy ~/src/elisp to /usr/share/emacs23/site-lisp.

Install also:

emacs-goodies (use synaptic): session.el is included here. $ sudo apt-get install emacs-goodies-el
quack.el is dropped from emacs-goodies-el. So, download from below and put it to ~/src/elisp/quack.el (or formac):
https://www.neilvandyke.org/quack/
pymacs (use synaptic)
python-mode (use synaptic)
css-mode (use synaptic, will install also html-helper-mode)
anthy-el (use synaptic)
auto-complete (http://www.emacswiki.org/emacs/AutoComplete). Copy under /usr/share/emacs23/site-lisp/undo-tree/
undo-tree (http://www.emacswiki.org/emacs/UndoTree). Install under /usr/share/emacs23/site-lisp/auto-complete. Make dir ~/.emacs.d/auto-install.
highlight-symbol (http://nschum.de/src/emacs/highlight-symbol/). Install under /usr/share/emacs23/site-lisp. Press F3 to hightlight the symbol in current location. Press F12 to 'Go to definition' (as in Visual Studio), Shift-F12 to go to next symbol.
emacs23-common-non-dfsg
smooth-scrolling.el (in ~/.emacs.d)
jade-mode, jshint, to enable REPL for JavaScript (in ~/.emacs.d)
highlight-parentheses.el, copy to /usr/share/emacs24/site-lisp/
sml-mode, by ELPA with M-x list-packages and find sml-mode.
Copy ~/src/buff-sel.el to /usr/share/emacs24/site-lisp
emacs-mozc
For python, keep using TABS in case of file that is already using TABS. But, the default is using space:
- See: https://emacs.stackexchange.com/questions/32140/python-mode-indentation?rq=1
- To untabify the tabs to space:
  - 1. Select all region
  - 2. M-x untabify

And, below is a list of some important keybinding when using Emacs as IDE:

C-c C-c: compile (in Python-mode, C-c C-c will execute the python code)
C-x 2: create two top-bottom frame
C-x 3: create two left-right frame
C-x 1: reduce to 1 frame
C-x o: move to other frame (activate other frame)
C-x k: kill buffer in the frame
C-x 0: just kill the frame, the buffer is alive
C-x b: switch to different buffer in the active frame
C-x C-b: display buffer-list
In "alias emacs='TERM=xterm emacs -nw .bashrc' , then C-x C-z: Stop / suspend current buffer, go to prompt. fg to go back to emacs.
M-x 2C-two-columns: create two column frame <==== C-x 3 may be better. Half-vertical split.
M-x 2C-dissociate (performed in 2C-two-column mode): in case the two columns are not used to edit the same buffer, then need to dissociate these 2 columns
M-x term: call terminal (DO NOT use M-x terminal emulator)
C-r C-c: mark region, then C-r C-c to comment region
C-r C-u: mark region, then C-r C-u to uncomment region
ls -lrt

http://www.gnu.org/software/emacs/manual/html_node/emacs/Rectangles.html
- M-x string-insert-rectangle
- C--: Control + -, for navigate backward (pop-to-mark-command)
- Navigating parentheses:
  - Find pairing / matching parentheses: For parentheses, braces and brackets just double clicking on them does the trick.
  - Go to one-of-matching parentheses (both begin and end parentheses will be highlighted), then:
    - If now in begin-par, then M-C-n (forward-list) will jump to matching end-par.
    - If now in end-par, them M-C-p (backward-list) will jump to matching begin-par.
- Emacs + REPL for JavaScript
  - C-c ! <= Open *js* buffer for REPL. Close with C-d in the REPL buffer. Can do ".help", etc.
  - C-x o <= Toggle between editor buffer and *js* buffer
  - C-c C-j <= Send current line to REPL buffer
  - C-c C-r <= Send highlighted region to REPL buffer (Changed to C-r C-r, because C-c means region copy)
  - C-c C-u <= Using npm jshint, check compilation/interpretation of the JS
  - C-m <= Jump to the error line from REPL buffer to the JS
- Using emacs keyboard macro
  - C-x ( <= start defining a keyboard macro
  - C-x ) <= finish defining a keyboard macro
  - C-u 37 C-x e <= execute the keyboard macro 37 times
  - C-x e e e <= execute the keyboard macro the same number of 'e' times
  - M-x apply-macro-to-region-lines <= select region then apply macro inside this region
- See the sr-speedbar: OR use C-x z to repeat command with z, by first execute command to be repeated: C-x { C-x z z z
  - C-x { decrease window width.
- Joining TWO lines to one line:
- http://stackoverflow.com/questions/445225/emacs-command-to-delete-up-to-non-whitespace-character
  - delete-indentation: M-^
  - With Emacs auto-fill, where each line is limited to 80 characters, after joining with M-^, then go to end-of-line with C-e. Here, do NOT press "Enter", but instead press "Space followed with enter".
- Select entire buffer (Command-a): C-x h
- multiple-cursors: https://github.com/magnars/multiple-cursors.el
  - Joining multiple-lines:
    1. 1. Select region (C-x h, for selecting all region.
    2. 2. M-x mc/edit-lines
    3. 3. M-^
    4. 4. C-g
    5. 5. C-e, SPACE (DO NOT PRESS ENTER)
- M-x mc/edit-beginning-of-lines. Press C-a then TAB to go to first non-zero white space, i.e., indent.
- Select-region, then M-x mc/edit-lines, C-e (go to end of line) is OK.
- Select-region, then M-x mc/edit-lines, C-a etc., M-x mc/insert-numbers.
  - C-' to hide all lines without a cursor, press C-' again to unhide
  - Basically, select-region, then M-x mc/...
  - Try pressing mc/mark-all-like-this-dwim on a tagname in html-mode.

Eclipse Helios

Installed plugin

1. Install eclipse color-theme plugin: http://www.eclipsecolorthemes.org/

If you are on Eclipse 3.6 (Helios, but NOT the classic package), the easiest way to install the plugin is from the Eclipse Marketplace. Go to Help→Eclipse Marketplace..., then search for Eclipse Color Theme and install it.

After the installation, go to Window→Preferences→General→Appereance→Color Theme to change the color theme.

(If Eclipse Marketplace is not installed, then install Eclipse Market place client from Help -> Install new software)

2. Mylyn plugin (seems to be installed by default)

3. emacs+ plugin

Modified some binding as in below screenshot. Unbind C-x and undo (Ctrl-Shift--), Ctrl-h, C-c, C-y, C-v.

QUICK FIX: Create a new workspace on the new desired location and import the projects from the old workspace. Do not forget to check the “Copy projects into workspace” checkbox so that the projects get copied to the new workspace directory. From this point on autocomplete should be back on its feet.

http://eclipse.dzone.com/news/create-new-eclipse-workspace-w

So the short answer is: If you want to create a new eclipse workspace and preserve all your settings,

simply copy the .metadata/.plugins/org.eclipse.core.runtime/.settings directory into your new workspace directory.

Backup command

mirrordir was mentioned as one of backup command, but since it seems buggy, it is not included in Ubuntu repository anymore:

http://www.linux-archive.org/ubuntu-masters-universe/276979-rm-mirrordir-rom-buggy-package-no-longer-maintained-upstream.html

http://ubuntica.com/easily-back-up-your-data-with-mirrordir.html

http://www.cyberciti.biz/tips/howto-duplicate-directory-using-mirrordir-command.html

So, use rsync as the backup command. The command rsync can be executed as below. Then we can check the difference between the source and the destination directory using diff -r (behaves similar to whichdiff.pl).

rsync -av --delete --force --exclude .metadata --exclude '*~' /home/username/workspace /home/username/backup/
diff -r workspace backup/workspace

sudo apt-get update
do-release-upgrade: 2 times (12.10->13.04 and 13.04->13.10): Failed!

Use boot DVD and install. Put boot loader at the same partition with the ubuntu installed partition.

Initial setting

Disable bluetooth: http://linuxg.net/how-to-disable-bluetooth-at-startup-5-practical-methods/

Add below line to /etc/rc.local, before exit 0:

/etc/init.d/bluetooth stop

Key setting: launch "Home Folder" (Nautilus) with Super+E

Nautilus does not create double pane with F3 anymore...

http://askubuntu.com/questions/285588/is-there-a-way-to-restore-nautilus-split-screen-f3-feature (Not working)

http://www.webupd8.org/2013/04/get-nautilus-34-features-back-in-ubuntu.html

Hide ubuntu one icon from panel:

gksudo gedit /etc/xdg/autostart/ubuntuone-launch.desktop

change "NoDisplay=true" to NoDisplay=false

If not working, then just remove /etc/xdg/autostart/ubuntuone-launch.desktop

Nautilus open terminal here.

DONT USE gnome-tweak-tool or dconf-editor anymore. Just use unity-tweak-tool.

Xmodmap is strange + Xmodmap now Swap and set muhenkan

http://d.hatena.ne.jp/taczge/20131219/1387434104

http://home.hiroshima-u.ac.jp/tkura/linux/xmodmap.html

xmodmap $HOME/.Xmodmap 2> /dev/null

So, in the application startup (自動起動), add:

sh -c '/usr/bin/xmodmap /home/username/.Xmodmap'

Also, swap Ctrl, caps-lock does not work anymore (when set in dconf-editor).

So, .Xmodmap must also swap Ctrl, caps-lock! (use xev to check the key)

Finally:

http://qiita.com/ysaito8015@github/items/0fd4ec3076293bc372d4

clear Control

keycode 102 = Control_L

add Control = Control_L

keycode 100 = Control_R

add Control = Control_R

keycode 37 = Caps_Lock NoSymbol Caps_Lock

keycode 66 = Control_L NoSymbol Control_L

clear Lock

add Control = Control_L

That is, Muhenkan, henkan to control and swap caps lock to control all 3 are handled in .Xmodmap.

Use fcitx + mozc instead of ibus + mozc

Xmodmap is reset when using japanese input system ibus + mozc:

https://forums.ubuntulinux.jp/viewtopic.php?pid=101413

So, use fcitx + mozc instead of ibus + mozc.

Modify the Japanese input toggle from Ctrl+Space to Ctrl+O. But, cannot toggle with Ctrl+O. Good thing is, Ctrl+Space is released, so can be used in Emacs24 for mark region start.

Nvidia driver + nvidia-settings in 13.10

http://news.softpedia.com/news/How-to-Install-the-Latest-NVIDIA-331-20-Drivers-in-Ubuntu-13-10-399182.shtml (Failed)

So, try just to reinstall the nvidia driver as below:

http://askubuntu.com/questions/362690/drivers-for-ubuntu-13-10

Procedure:

Ctrl+Alt+F1 : go to terminal without X
Remove the nvidia driver ppa: sudo apt-add-repository --remove ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get install nvidia-current

However, this failed also.

So, reinstall Ubuntu 13.10, and then "Use enable additional driver" in "Software & update" only.

Set notebook PC monitor default brightness

http://askubuntu.com/questions/76081/brightness-not-working-after-installing-nvidia-driver (Not working)

So, tried adding below line to ~/.xinitrc:

nvidia-settings --load-config-only & . /etc/X11/xinit/xinitrc

However, this failed also. The culprit is that "nvidia-settings -l", the -l option, does NOT change the brightness. The "nvidia-settings" correctly change the brightness.

So, in the startup-application (Lens -> 自動起動), change:

sh -c '/usr/bin/nvidia-settings --load-config-only'

to:

sh -c '/usr/bin/nvidia-settings'

Eclipse menu in ubuntu 13.10 is cut/corrupted

http://stackoverflow.com/questions/19452390/eclipse-menus-dont-show-up-after-upgrading-to-ubuntu-13-10

Modify /usr/share/applications/eclipse.desktop (if exist) or .local/share/applications/eclipse.desktop:

Exec=env UBUNTU_MENUPROXY= /usr/local/eclipse/eclipse

Maybe source .local/share/applications/eclipse.desktop

Docker

Refer to:
https://qiita.com/iganari/items/fe4889943f22fd63692a
https://docs.docker.com/install/linux/docker-ce/ubuntu/
sudo apt-get update, upgrade, dist-upgrade

sudo apt-get remove docker docker-engine docker.io containerd runc
sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common
Add docker's official GPG: curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
Verify: sudo apt-key fingerprint 0EBFCD88
Add repository (stable): sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io
Confirm that docker is active: sudo systemctl status docker
docker --version: OK, but docker version, docker ps: Got permission denied. sudo docker version, sudo docker ps: OK.
So, need to add the user to Docker group to enable contacting to docker engine without sudo.
- whoami: username
  - sudo gpasswd -a username docker
  - cat /etc/group | grep docker
- sudo chmod 666 /var/run/docker.sock
- docker ps with username is OK now.
- The rest, see MacWork
