== Introduction ==
<includeonly>
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. 
{{#set:arch={{{arch|}}}|arch_desc={{{arch_desc|}}}}}


'''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.'''

The easiest and quickest way:
</includeonly>
<console>
###i## emerge -avt x11-wm/i3
</console>
 
=== Manual ===
 
==== Tarball ====
 
Download the latest version from the i3 website.
[http://i3wm.org/downloads/i3-4.8.tar.bz2 i3-4.8]
 
<console>
###i## cd /PATH/TO/TARBALL
###i## make
###i## sudo make install
</console>
 
==== Git ====
 
<console>
###i## git clone git://code.i3wm.org/i3
###i## cd i3
###i## make
###i## sudo make install
</console>
 
== 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>
###i## emerge x11-apps/xrandr
</console>
and if you want a GUI with xrandr:
<console>
###i## emerge x11-misc/arandr
</console>
 
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>
###i## startx
</console>
or, in a case similar to mine:
<console>
###i## xinit qtile
</console>
 
=== i3 config ===
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:
<div style="height:250px;overflow:scroll;color:green"><pre>
set $mod Mod1

These scripts can be found in /usr/bin/
 
=== i3nagbar ===
 
The i3nagbar is the error bar that pops up on top of the screen when there is an error in the i3 configuration.
 
=== i3-sensible-editor ===
 
i3-sensible-editor is callen when the user presses the edit button on the i3nagbar.  If $EDITOR is set, that editor will be used, else i3-sensible-editor will open the first editor that is installed according to the order in i3-sensible-editor.  If the user has a preference, he will set $EDITOR.
 
=== i3-sensible-terminal ===
 
i3-sensible-terminal is called when the user opens a terminal.  If $TERMINAL is set, that terminal will be used, else i3-sensible-terminal will open the first terminal that is installed according to the order in i3-sensible-terminal.  If the user has a preference, he will set $TERMINAL.
 
=== i3-sensible-pager ===
 
i3-sensible-pager is called when the user presses the view button on the i3nagbar.  If $PAGER is set, that pager will be used, else i3-sensible-pager will open the first pager that is installed accordding to the order in i3-sensible-pager.  If the user has a preference, he will set $PAGER.
 
=== i3status ===
 
i3status generates a status bar similar to conky in i3.  i3status replaces dzen2, xmobar, and other similar applications used in older versions of i3.  It is suggested to create an <tt>~/.i3status.conf</tt> file to configure the i3status bar locally. 
A sample <tt>~/.i3status.conf</tt>:
 
<pre>
general {
        colors = true
        interval = 5
}
 
order = "disk /"
order += "disk /home"
order += "ethernet eth0"
order += "cpu_temperature 0"
order += "cpu_temperature 1"
order += "cpu_temperature 2"
order += "cpu_temperature 3"
order += "load"
order += "time"
 
ethernet eth0 {
        # if you use %speed, i3status requires the cap_net_admin capability
        format_up = "Eth0: %ip (%speed)"
        format_down = "Eth0: down"
}
 
time {
        format = "%a:%d-%b-%Y %I:%M:%S %p"
}
 
load {
        format = "Load: %5min"
}
 
cpu_temperature 0 {
format = "T1: %degrees °C"
path = "/sys/devices/platform/coretemp.0/temp2_input"
}
 
cpu_temperature 1 {
format = "T2: %degrees °C"
path = "/sys/devices/platform/coretemp.0/temp3_input"
}
 
cpu_temperature 2 {
format = "T3: %degrees °C"
path = "/sys/devices/platform/coretemp.0/temp4_input"
}
 
cpu_temperature 3 {
format = "T4: %degrees °C"
path = "/sys/devices/platform/coretemp.0/temp5_input"
}
 
disk "/" {
        format = "/: %free"
}
 
disk "/home" {
format = "/home: %free"
}
</pre>
 
== dmenu ==
 
i3 uses {{Package|x11-misc/dmenu}} as the application launcher. To install it, run the following:
 
<console>
###i## emerge dmenu
</console>
 
{{fancynote| The default key-binding for dmenu is Mod1+d.}}
 
== Default Keybindings ==

== Troubleshooting ==
 
=== i3status ===
 
{{fancynote| i3status may not work out of box}} The permissions may be set to: <tt>-r-xr-x---</tt>: when run as non-root, sh would return with "permission denied".
If i3status does not work for you, this can be easily corrected by changing the permissions.
<console>
###i## sudo chmod 755 /usr/bin/i3status
</console>
