| == Introduction == | | ==Introduction== |
| i3 is a tiling window manager that is based upon experiences the developers shared while attempting to fix/hack wmii. i3 has the ability for either floating windows, which you can resize and move, and tiling windows. i3 uses a tree as a data structure to allow for more flexibility. i3 defaults with home-row key-bindings which are quick and easy to get beginners off the ground.
| | A hostname is a unique name created to identify a machine on a network. In computer networking, a hostname is a label that is assigned to a device connected to a computer network and that is used to identify the device in various forms of electronic communication such as the World Wide Web, e-mail or Usenet. Hostnames may be simple names consisting of a single word or phrase, or they may be structured. |
| | | ==Configuration== |
| '''NOTE: This wiki is made following the steps produced to get a working i3 using xrandr instead of xinerama, ATI proprietary drivers instead of radeon drivers, a dual-monitor setup, and no login manager. For Nvidia and Twinview users, a link is supplied in [[#X11 and xrandr|X11 and xrandr]]. Xinerama was initially used and worked in the dual-monitor setup so it possible to substitute xinerama for xrandr with minimal changes.'''
| | In Funtoo Linux <code>/etc/conf.d/hostname</code> is the only configuration file for setting a hostname. In OpenRC framework <code>/etc/conf.d/foo</code> is the configuration file for a corresponding Init script <code>/etc/init.d/foo</code>. With the case of hostname, default value in <code>/etc/conf.d/hostname</code> is set to ''localhost'', means when system boots and OpenRC's <code>/etc/init.d/hostname</code> script started a hostname getting only ''localhost'' name. How it looks? In your shell promt this will look in following way, an example for root: |
| | |
| == Installation ==
| |
| | |
| === Portage ===
| |
| | |
| The easiest and quickest way:
| |
| <console> | | <console> |
| ###i## emerge -avt x11-wm/i3 | | localhost ~ # ##i## Hello :) |
| </console> | | </console> |
| | | Let's play a bit with a configuration. Open <code>/etc/conf.d/hostname</code> with your favorite editor and set a hostname of your choice. Below, I will use a real examples from one of my working test boxes. |
| === Manual ===
| |
| | |
| ==== Tarball ====
| |
| | |
| Download the latest version from the i3 website.
| |
| [http://i3wm.org/downloads/i3-4.8.tar.bz2 i3-4.8]
| |
| | |
| <console> | | <console> |
| ###i## cd /PATH/TO/TARBALL | | localhost ~ # ##i## nano /etc/conf.d/hostname |
| ###i## make
| |
| ###i## sudo make install
| |
| </console> | | </console> |
| | | Let's set it to hostname="oleg-stable.host.funtoo.org". Save the file and restart a hostname service: |
| ==== Git ==== | |
| | |
| <console> | | <console> |
| ###i## git clone git://code.i3wm.org/i3 | | localhost ~ # ##i## service hostname restart |
| ###i## cd i3
| |
| ###i## make
| |
| ###i## sudo make install
| |
| </console> | | </console> |
| | | Now, let's examine our changes, after a restarting a hostname |
| == Setup ==
| |
| | |
| === xinitrc ===
| |
| | |
| Edit <tt>~/.xinitrc</tt>:
| |
| | |
| <pre>
| |
| exec i3
| |
| </pre>
| |
| | |
| | |
| For i3 logging, edit <tt>~/.xinitrc</tt>:
| |
| | |
| <pre>
| |
| exec i3 -V -d all >~/.i3/i3log-$(date +'%F-%k-%M-%S') 2>&1
| |
| </pre>
| |
| | |
| If you are using Nvidia or for some reason don't use xrandr, edit ~/.xinitrc
| |
| <pre style="color:green">exec i3 --force-xinerama</pre>
| |
| and nvidia with logging:
| |
| <pre style="color:green">exec i3 --force-xinerama -V -d all >~/.i3/i3log-$(date +'%F-%k-%M-%S') 2>&1</pre>
| |
| Example ~/.xinitrc that uses consolekit and dbus in launch and also logs on exit.
| |
| <pre style="color:purple">#!/bin/zsh
| |
| xrdb -merge ~/.Xresources
| |
| xcompmgr &
| |
| | |
| if [[ $1 == "i3" ]]; then
| |
| exec ck-launch-session dbus-launch --sh-syntax --exit-with-session i3 -V -d all > ~/.i3/i3log-$(date +'%F-%k-%M-%S') 2>&1
| |
| elif [[ $1 == "razor" ]]; then
| |
| exec ck-launch-session dbus-launch startrazor
| |
| elif [[ $1 == "awesome" ]]; then
| |
| exec ck-launch-session dbus-launch awesome
| |
| elif [[ $1 == "qtile" ]]; then
| |
| exec ck-launch-session dbus-launch ~/.qtile-session
| |
| else
| |
| echo "Choose a window manager"
| |
| fi</pre>
| |
| | |
| <div id="X11 and xrandr"></div>
| |
| | |
| === X11 and xrandr ===
| |
| | |
| === X and RandR ===
| |
| '''NOTE: RandR and Xinerama do not play together. Use one or the other.'''
| |
| | |
| I use an AMD HD 6870 with 3 monitors (2 DVI and 1 with an AMD validated Mini DisplayPort™ to DVI dongle).
| |
| | |
| Install {{Package|x11-apps/xrandr}}:
| |
| <console> | | <console> |
| ###i## emerge x11-apps/xrandr | | oleg-stable ~ # ##i## Hello :) |
| </console> | | </console> |
| and if you want a GUI with xrandr: | | == Diving deeper== |
| | Notice, that in above output we seeing a shortened hostname and not a FQDN (Fully Qualified Domain Name). Don't be frustrated. This is how default bash promt <code>PS1</code> set. To get nice promts, please, follow http://www.funtoo.org/Prompt_Magic |
| | Another way to test our settings is using a '''hostname''' command. Here we will show only some of it's features. Let's try to execute '''hostname''' command: |
| <console> | | <console> |
| ###i## emerge x11-misc/arandr | | oleg-stable ~ # ##i## hostname |
| | oleg-stable.host.funtoo.org |
| </console> | | </console> |
| | | Now we see our fully qualified domain name hostname just how we configured it in <code>/etc/conf.d/hostname</code> in above paragraph. To get a short hostname we need to set '''-s ''' (short) argument to hostname command. |
| If you do not have X configured yet, follow the link on the [http://en.gentoo-wiki.com/wiki/X.Org Gentoo Wiki]
| |
| | |
| My xorg.conf.d folder for example: [https://github.com/akiress/dotfiles/blob/master/etc/X11/xorg.conf.d/30-screen.conf 30-screen.conf]
| |
| | |
| Since the names of the monitors are already known in xrandr, I just use those names in my 30-screen.conf configuration. It doesn't matter what you use in your X configuration however.
| |
| | |
| Once you have X configured however you like, start qtile with either:
| |
| <console> | | <console> |
| ###i## startx | | oleg-stable ~ # ##i## hostname -s |
| | oleg-stable |
| </console> | | </console> |
| or, in a case similar to mine:
| | Good! Hostname offers more then just displaying a system host name but can also set one. Let's try: |
| <console> | | <console> |
| ###i## xinit qtile | | oleg-stable ~ # ##i## hostname foo.bar.baz |
| | oleg-stable ~ # ##i## hostname |
| | foo.bar.baz |
| </console> | | </console> |
| | As you can see, we changed a hostname on-the-fly. This is not recommended way. |
| | {{fancywarning|Please, notice that using '''hostname''' command to configure will work temporary for a current session and will be reverted back to a value set in <code>/etc/conf.d/hostname</code> file with next system restart.}} |
|
| |
|
| === i3 config ===
| | Now that we got a brief description of a hostname and basic configuration steps, its time to reflect another important case which is directly related to a Funtoo Linux hostname generation, a hosts. |
| The i3 configuration file can be found in /etc/i3/config, but I suggest that you copy the file into a local ~/.i3 directory.
| |
| <pre># mkdir -p ~/.i3 && cp /etc/i3/config ~/.i3/config</pre>
| |
| Open up ~/i3/config in your editor of choice.
| |
| <code style="color:green">set $mod Mod1</code> assigns the variable $mod to be Mod1. In i3, Mod1 is the Alt key. If you wish to use the Windows key then use <code style="color:green">set $mod Mod4</code> In the keybinding section, $mod is used in place of Mod1 in the case that you do wish to change the modifier. In the workspace key, the keybindings are set with Mod1 instead of the variable, so remember to change those bindings manually if you are replacing the Mod1 modifier. Else you can change Mod1 in those sections to $mod and change all the keybindings at the same time by setting the $mod variable.
| |
| <pre style="color:green">set $mod Mod1</pre>
| |
| To have programs start automatically in i3, use the command <code style="color:green">exec APPLICATION</code>. This is the section that the xrandr screen layout bash file created earlier will be placed. The i3bar is a tray and status bar combination. If you have applications that run in the system tray that you want to autostart, call those applications with exec.
| |
| <pre style="color:green">exec /PATH/TO/XRANDR-BASH-FILE
| |
| exec NAME OF BROWSER
| |
| exec NAME OF EDITOR
| |
| exec volumeicon
| |
| exec dropbox</pre>
| |
| In the workspace section, you have the opportunity to name the workspaces by setting either the number of the workspace, the name of the workspace, or the number and name of the workspace. <code style="color:green">bindsym KEYBIND workspace NAME/NUMBER OF WORKSPACE</code>. Remember to use quotes when naming a workspace.
| |
| <pre style="color:green">bindsym Mod1+1 workspace 1
| |
| bindsym Mod1+1 workspace "my first workspace"
| |
| bindsym Mod1+1 workspace "1: my first workspace"</pre>
| |
| To assign a workspace to a certain output you will need the output from running xrandr again if you do not remember which connections are being used. In the example from [#X11 and xrandr|X11 and xrandr], the connected outputs are DFP3 and DFP4. To assign the workspace, you need to add <code style="color:green">workspace NAME OF WORKSPACE or NUMBER output CONNECTED OUTPUT</code>. There are several types of outputs so make sure that you are using the connected outputs from xrandr when assigning workspaces, else the workspace will not show up.
| |
| <pre style="color:green">workspace 1 output DFP3
| |
| workspace "my first workspace" output DFP3
| |
| workspace "1: my first workspace" output DFP3
| |
| workspace "2: my second workspace" output DFP4</pre>
| |
| To assign a program to a certain workspace, you will need to run xprop. If you do not have xprop, emerge it.
| |
| <pre># emerge -avt x11-apps/xprop</pre>
| |
| To run xprop, open a terminal and run <pre># xprop</pre> Your mouse cursor should become a crosshair and you will want to mouse over the window that contains the running application. Click on that window and xprop will then output the window information. The easiest way to assign a program is to look for <pre style="color:green">WM_CLASS(STRING) = "INSTANCE", "CLASS"</pre> Be sure to note that the window INSTANCE is before the window CLASS. In the config file, add <code style="color:green">assign [class="^INSTANCE$" instance="^CLASS$] NAME OF WORKSPACE</code>. For aesthetic purposes, you can add → before NAME OF WORKSPACE, but mind that the → is a UTF-8 character and not <code>-></code>. For the assignments, do not put the workspace name within quotes as you do when naming them and setting their output.
| |
| <pre style="color:green">
| |
| assign [class="^Chromium-browser$" instance="^chromium-browser$"] 1
| |
| assign [class="^Chromium-browser$" instance="^chromium-browser$"] web
| |
| assign [class="^Chromium-browser$" instance="^chromium-browser$"] 1: web
| |
| assign [class="^Chromium-browser$" instance="^chromium-browser$"] → 1
| |
| assign [class="^Chromium-browser$" instance="^chromium-browser$"] → web
| |
| assign [class="^Chromium-browser$" instance="^chromium-browser$"] → 1: web</pre>
| |
| For aesthetic purposes, their are three types of borders for the windows. This can be set by adding <code style="color:green">new_window <normal|1pixel|none></code>. There are also keybindings that allow you to switch between the 3 border styles.
| |
| <pre style="color:green">new_window 1pixel
| |
| bindsym $mod+t border normal
| |
| bindsym $mod+y border 1pixel
| |
| bindsym $mod+u border none</pre>
| |
| The orientation for new workspaces can be set by adding <code style="color:green">default_orientation <horizontal|vertical|auto></code>
| |
| <pre style="color:green">default_orientation horizontal</pre>
| |
|
| |
|
| A sample ~/.i3/config:
| | ==Hosts case== |
| <div style="height:250px;overflow:scroll;color:green"><pre> | | As per man page <code>hosts</code> stands for static table lookup for hostnames and it's configuration file is <code>/etc/hosts</code>. Here is how it looks |
| set $mod Mod1
| | {{file|name=/etc/hosts|body= |
| | # Auto-generated hostname. Please do not remove this comment. |
| | 127.0.0.1 oleg-stable.host.funtoo.org oleg-stable localhost localhost.localdomain |
| | ::1 oleg-stable.host.funtoo.org oleg-stable localhost localhost.localdomain |
| | }} |
| | As you can see it has entries from our <code>/etc/conf.d/hostname</code>. As you may have guessed, in Funtoo Linux <code>/etc/hosts</code> file entries are auto-generated, when OpenRC hostname service starts. Previously, it is used to edit <code>/etc/hosts</code> manually. In Funtoo Linux there is no such need. |

Introduction
A hostname is a unique name created to identify a machine on a network. In computer networking, a hostname is a label that is assigned to a device connected to a computer network and that is used to identify the device in various forms of electronic communication such as the World Wide Web, e-mail or Usenet. Hostnames may be simple names consisting of a single word or phrase, or they may be structured.
Configuration
In Funtoo Linux /etc/conf.d/hostname is the only configuration file for setting a hostname. In OpenRC framework /etc/conf.d/foo is the configuration file for a corresponding Init script /etc/init.d/foo. With the case of hostname, default value in /etc/conf.d/hostname is set to localhost, means when system boots and OpenRC's /etc/init.d/hostname script started a hostname getting only localhost name. How it looks? In your shell promt this will look in following way, an example for root:
localhost ~ # Hello :)
Let's play a bit with a configuration. Open /etc/conf.d/hostname with your favorite editor and set a hostname of your choice. Below, I will use a real examples from one of my working test boxes.
localhost ~ # nano /etc/conf.d/hostname
Let's set it to hostname="oleg-stable.host.funtoo.org". Save the file and restart a hostname service:
localhost ~ # service hostname restart
Now, let's examine our changes, after a restarting a hostname
oleg-stable ~ # Hello :)
Diving deeper
Notice, that in above output we seeing a shortened hostname and not a FQDN (Fully Qualified Domain Name). Don't be frustrated. This is how default bash promt PS1 set. To get nice promts, please, follow http://www.funtoo.org/Prompt_Magic
Another way to test our settings is using a hostname command. Here we will show only some of it's features. Let's try to execute hostname command:
oleg-stable ~ # hostname
oleg-stable.host.funtoo.org
Now we see our fully qualified domain name hostname just how we configured it in /etc/conf.d/hostname in above paragraph. To get a short hostname we need to set -s (short) argument to hostname command.
oleg-stable ~ # hostname -s
oleg-stable
Good! Hostname offers more then just displaying a system host name but can also set one. Let's try:
oleg-stable ~ # hostname foo.bar.baz
oleg-stable ~ # hostname
foo.bar.baz
As you can see, we changed a hostname on-the-fly. This is not recommended way.
Warning
Please, notice that using hostname command to configure will work temporary for a current session and will be reverted back to a value set in /etc/conf.d/hostname file with next system restart.
Now that we got a brief description of a hostname and basic configuration steps, its time to reflect another important case which is directly related to a Funtoo Linux hostname generation, a hosts.
Hosts case
As per man page hosts stands for static table lookup for hostnames and it's configuration file is /etc/hosts. Here is how it looks
/etc/hosts
# Auto-generated hostname. Please do not remove this comment.
127.0.0.1 oleg-stable.host.funtoo.org oleg-stable localhost localhost.localdomain
::1 oleg-stable.host.funtoo.org oleg-stable localhost localhost.localdomain
As you can see it has entries from our /etc/conf.d/hostname. As you may have guessed, in Funtoo Linux /etc/hosts file entries are auto-generated, when OpenRC hostname service starts. Previously, it is used to edit /etc/hosts manually. In Funtoo Linux there is no such need.
What about custom hosts entries? This can be easily configured with 'aliases'. For example you want to have a hosts for your remote router or a computer in home LAN. Let's try to modify /etc/conf.d/hostname with adding following - my remote computer oleg.distant.home has an IP 10.1.1.2:
oleg-stable ~ # echo 'aliases="10.1.12 oleg.distant.home"' >> /etc/conf.d/hostname
oleg-stable ~ # service hostname restart
Examine our changes:
oleg-stable ~ # cat /etc/hosts
/etc/hosts
# Auto-generated hostname. Please do not remove this comment.
10.1.1.2 oleg.distant.home
127.0.0.1 oleg-stable.host.funtoo.org oleg-stable localhost localhost.localdomain
::1 oleg-stable.host.funtoo.org oleg-stable localhost localhost.localdomain
