Tmux is a terminal multiplexer (just as [[Package:Screen (Terminal Multiplexer)|screen]], which is generally installed by default on servers). It enables you to run multiple terminals in one. You can arrange them in multiple tabs that you can split into multiple panes as well.


== Installation ==
==== Upgrading from GNOME 3.12 ====
 
To update either ''gnome'' or ''gnome-light'' run the following command:
 
{{console|body=
# ##i## emerge -vauDN world
}}
=== Subsystems ===
 
==== Bluetooth ====
 
For bluetooth support, ensure that:
 
# Bluetooth support is enabled in your kernel (using modules is fine).
# Your bluetooth hardware is turned on.
# Add the <code>bluetooth</code> startup script to the default runlevel, and start it.
 
This can be done as follows:


<console>
<console>
###i## emerge -a tmux
# ##i##rc-update add bluetooth default
# ##i##rc
</console>
</console>


== Getting Started ==
Once this is done, you should now be able to navigate to ''Settings'' -> ''Bluetooth'' and turn bluetooth on. The icon next to devices should now animate and you should be able to discover and add devices such as keyboards.


To launch Tmux, run <code>tmux</code> in a terminal. This should clear your current terminal and display a <i>status bar</i> on the bottom. In this status bar, you should see something like <i>"[0] 0:bash*"</i>. This means you are on session 0 (<b>[0]</b>), window 0 (<b>0:</b>) and you run "bash".
{{Note|1=
Additional kernel drivers may need to be enabled for certain input devices. For example, for the bluetooth Apple Magic Trackpad, the following option must be enabled in your kernel:


Tmux uses <b><code>Ctrl+b</code></b> as default prefix. This means that before issuing any command you will have to hit <b><code>Ctrl+b</code></b> to tell tmux you are asking <i>it</i>. For instance, type <b><code>Ctrl+b</code></b> and then <b><code>%</code></b>. This should split vertically the window to add a new pane. Now issue <b><code>Ctrl+b "</code></b>, this will split the new pane horizontally to create a new pane. You can switch against panes with <b><code>Ctrl+b Left/Up/Right/Down</code></b> (Left/Up/Right/Down being the arrow keys).
{{kernelop|title=Device Drivers,HID support,HID bus support,Special HID drivers|desc=
<M> Apple Magic Mouse/Trackpad multi-touch support
}}}}


Another cool stuff is windows. Splitting your window into panes is good, but for readability purpose, you can't indefinitely split your window. So you can open a new window (which would behave more like a tab) by issuing <b><code>Ctrl+b c</code></b>. Your current window will be replaced by a brand new one. However you will notice that your status bar now looks like this <i>"[0] 0:bash- 1:bash*"</i>. The minus symbol (<b>-</b>) means this is the last visited window. The asterisk symbol (<b>*</b>) means this is the current window. You can add panes to this window as well. To go back to the first window, issue <b><code>Ctrl+b 0</code></b>. Generally speaking, issue <b><code>Ctrl+b <window-id></code></b> to go to the window <i><window-id></i>.
==== Printing ====


You can do much more with tmux, but this is the minimum to know if you want to quickly get started.
To enable printing support, add <code>cupsd</code> to the default runlevel:


== Keyboard Shortcuts ==
<console>
# ##i##rc-update add cupsd default
# ##i##rc
</console>
 
You should now be able to navigate to ''Settings'' -> ''Printers'' and add printers to your system, and print.
 
==== Scanning ====
 
To enable scanning support, add your user account to the <code>lp</code> group. This will allow your user to access the USB scanner.
 
Then, <code>emerge xsane</code>, and run it. It should be able to access your scanner.
 
=== Finishing Touches ===

|-
|| <code>C-b [</code> || Enter copy/scroll mode (type <code>q</code> to leave this mode)
|}


== Configuration ==
Typically, you will want to use <code>gdm</code>, the GNOME display manager, to log in to GNOME. This will allow you to log in graphically, rather than using the text console.
=== ~/.tmux.conf ===
Example tmux configuration shown below
<code>~/.tmux.conf</code> gets loaded on tmux startup.
{{file|name=~/.tmux.conf|lang=|desc=tmux configuration|body=
set -g base-index 1
set -g default-terminal "st-256color"
set -g history-limit 4096
set -g status-left ''
set -g status-right "#[bg=brightblack]#[fg=green] #T "
set -g status-style "bg=black"


setw -g pane-base-index 1
To enable gdm, edit <code>/etc/conf.d/xdm</code> and set <code>DISPLAYMANAGER</code> to <code>gdm</code> instead of <code>xdm</code>. Then, perform the following steps to add <code>xdm</code> to the default runlevel, and have it start automatically from now on when your system starts:
setw -g window-status-format "#[bg=magenta]#[fg=black] #I #[bg=brightblack]#[fg=green] #W "
setw -g window-status-current-format "#[bg=brightmagenta]#[fg=black] #I #[bg=green]#[fg=black] #W "


bind r source-file ~/.tmux.conf
{{Note|Funtoo's <code>/etc/init.d/xdm</code> initscript has been modified to start the requisite services <code>dbus</code>, <code>openrc-settingsd</code> and <code>consolekit</code> prior to starting <code>gdm</code>.}}
 
{{console|recipe=setup|desc=Enable the GNOME display manager|body=
# ##i## rc-update add xdm default
}}
}}


{{EbuildFooter}}
Then, if you want to start it now do:
 
{{console|body=
# ##i##rc
}}
 
But you should reboot to avoid having an open login terminal.
 
===== Setting up xinitrc (text log-in) =====
 
Adding the following to your <code>~/.xinitrc</code> file is sufficient:
 
<pre>
# Fix Missing Applications in Gnome
export XDG_MENU_PREFIX=gnome-
 
# Properly Launch the Desired X Session
exec ck-launch-session gnome-session
</pre>
 
Additionaly, if you need support for different input sources, there is no longer a need to configure IBus or SCIM in your <code>.xinitrc</code> file as GNOME uses IBus natively. Simply configure it in the Control Center under Region & Language.
 
=== Automatically Starting Applications at Login ===
 
When using an old-fashioned <code>.xinitrc</code>, starting up applications when X starts is relatively easy. When using GDM, this can still be accomplished, by using the <code>~/.xprofile</code> file. Here's my sample <code>.xprofile</code> to start <code>xflux</code> to dim the screen at night:
 
<pre>
xflux -z 87107
</pre>
 
{{Note|Remember to add a <code>&</code> at the end of any command that doesn't return to the shell prompt after running.}}
 
=== games ===
Gnome has several games that can be added on to your install.  By default most games are not included in gnome's emerge.
 
Users wishing to play games need to be added to the games group:
{{console|body=###i## gpasswd -a $USER games}}

What is GNOME?

"GNOME 3 is an easy and elegant way to use your computer. It is designed to put you in control and bring freedom to everybody. GNOME 3 is developed by the GNOME community, a diverse, international group of contributors that is supported by an independent, non-profit foundation." — GNOME

Prerequisites

From a Clean Install

Ensure that the X Window System is installed.

Preparing to emerge

To get your system ready to emerge gnome, first set your system flavor to desktop, and enable the gnome profile mix-in. To accomplish this, do the following:

root # eselect profile set-flavor funtoo/1.0/linux-gnu/flavor/desktop
root # eselect profile add funtoo/1.0/linux-gnu/mix-ins/gnome

Console: Set profile

By enabling the gnome mix-in, various USE and other settings will be optimized to provide you with a pain-free GNOME installation experience.

Emerging

You are provided with two packages that will pull in this desktop environment:

  • gnome
   Note

This is the "whole shabang" - pulls in a range of applications made for the gnome desktop environment including a few games, an archive manager, a system monitor, a web browser, a terminal, etc.

  • gnome-light
   Note

As the name implies, this pulls in the base minimal you need to get a functioning GNOME Desktop Environment.

GNOME 3.14 from a clean install

gnome

To emerge gnome run the following command

root #  emerge gnome

Console: Emerging GNOME

gnome-light

To emerge gnome-light run the following command

root #  emerge gnome-light

Console: Emerging a minimal GNOME environment (alternative)

Upgrading from GNOME 3.12

To update either gnome or gnome-light run the following command:

root #  emerge -vauDN world

Subsystems

Bluetooth

For bluetooth support, ensure that:

  1. Bluetooth support is enabled in your kernel (using modules is fine).
  2. Your bluetooth hardware is turned on.
  3. Add the bluetooth startup script to the default runlevel, and start it.

This can be done as follows:

root # rc-update add bluetooth default
root # rc

Once this is done, you should now be able to navigate to Settings -> Bluetooth and turn bluetooth on. The icon next to devices should now animate and you should be able to discover and add devices such as keyboards.

   Note

Additional kernel drivers may need to be enabled for certain input devices. For example, for the bluetooth Apple Magic Trackpad, the following option must be enabled in your kernel:

Under Device Drivers-->HID support-->HID bus support-->Special HID drivers:

<M> Apple Magic Mouse/Trackpad multi-touch support

Printing

To enable printing support, add cupsd to the default runlevel:

root # rc-update add cupsd default
root # rc

You should now be able to navigate to Settings -> Printers and add printers to your system, and print.

Scanning

To enable scanning support, add your user account to the lp group. This will allow your user to access the USB scanner.

Then, emerge xsane, and run it. It should be able to access your scanner.

Setting up xdm (GUI log-in)

Typically, you will want to use gdm, the GNOME display manager, to log in to GNOME. This will allow you to log in graphically, rather than using the text console.

To enable gdm, edit /etc/conf.d/xdm and set DISPLAYMANAGER to gdm instead of xdm. Then, perform the following steps to add xdm to the default runlevel, and have it start automatically from now on when your system starts:

   Note

Funtoo's /etc/init.d/xdm initscript has been modified to start the requisite services dbus, openrc-settingsd and consolekit prior to starting gdm.

root #  rc-update add xdm default

Console: Enable the GNOME display manager

Then, if you want to start it now do:

root # rc

But you should reboot to avoid having an open login terminal.

Setting up xinitrc (text log-in)

Adding the following to your ~/.xinitrc file is sufficient:

# Fix Missing Applications in Gnome
export XDG_MENU_PREFIX=gnome-

# Properly Launch the Desired X Session
exec ck-launch-session gnome-session

Additionaly, if you need support for different input sources, there is no longer a need to configure IBus or SCIM in your .xinitrc file as GNOME uses IBus natively. Simply configure it in the Control Center under Region & Language.

Automatically Starting Applications at Login

When using an old-fashioned .xinitrc, starting up applications when X starts is relatively easy. When using GDM, this can still be accomplished, by using the ~/.xprofile file. Here's my sample .xprofile to start xflux to dim the screen at night:

xflux -z 87107
   Note

Remember to add a & at the end of any command that doesn't return to the shell prompt after running.

games

Gnome has several games that can be added on to your install. By default most games are not included in gnome's emerge.

Users wishing to play games need to be added to the games group:

root # gpasswd -a $USER games

game list:

gnome-sudoku
gnome-mastermind
gnome-nibbles
gnome-robots
gnome-chess
gnome-hearts
gnome-mahjongg
gnome-mines
gnome-klotski
gnome-tetravex

game system emulators:

gnomeboyadvance
gnome-mud
