## Enlightenment

This comprises both the Enlightenment window manager and Enlightenment Foundation Libraries (EFL), which provide additional desktop environment features such as a toolkit, object canvas, and abstracted objects. It has been under development since 2005, but in February 2011 the core EFLs saw their first stable 1.0 release.

### Installation

Enlightenment can be installed with the package enlightenment.

You might also want to install terminology, which is an EFL-based terminal emulator that integrates well with Enlightenment.

#### From the AUR

Warning: Some of these PKGBUILDs use unstable development code. Use them at your own risk.

Development PKGBUILDs which download and install the very latest development code are available as enlightenment-gitAUR and its dependencies.

The following are EFL-based applications, most in an early stage of development and not yet released:

- ecrire-gitAUR – Ecrire text editor
- elbow-gitAUR – Elbow web browser
- eluminance-gitAUR – Eluminance photo browser
- enjoy-gitAUR – Enjoy music player
- eperiodiqueAUR – Eperiodique periodic table viewer
- ephoto-gitAUR – Ephoto picture viewer
- epymc-gitAUR – E Python Media Center
- equate-gitAUR – Equate calculator
- eruler-gitAUR – Eruler on-screen ruler and measurement tools
- efbb-gitAUR – Escape from Booty Bay angry birds style game
- elemines-gitAUR – Elemines minesweeper style game
- espionage-gitAUR – Espionage D-Bus inspector
- ev-gitAUR – ev simple picture viewer
- rageAUR and rage-gitAUR – Rage video player

### Starting Enlightenment

Simply choose Enlightenment session from your favourite display manager or configure xinitrc to start it from the console.

#### Entrance

Warning: Entrance is highly experimental, and does not have proper systemd support. Use it at your own risk.

Enlightenment has a new display manager called Entrance, which is provided by the entrance-gitAUR package. Entrance is quite sophisticated and its configuration is controlled by `/etc/entrance/entrance.conf`. It can be used by enabling `entrance.service` using systemd.

#### Starting Enlightenment manually

If you prefer to start Enlightenment manually from the console, add the following line to your `~/.xinitrc` file:

    ~/.xinitrc

    exec enlightenment_start

After that Enlightenment can be launched by typing `startx`. See xinitrc for details.

### Configuration

Enlightenment has a sophisticated configuration system that can be accessed from the Main menu's Settings submenu.

#### Network

ConnMan

Enlightenment's preferred network manager is ConnMan which can be installed from the connman package. Follow the instructions on Connman to do the configuration.

For extended configuration, you may also install Econnman (available in AUR as econnmanAUR or econnman-gitAUR) and its associated dependencies.

Adding the ConnMan Gadget to the Shelf

1. Settings -> Extensions -> Modules
2. under System
3. Connection Manager
4. Load that (select then hit Load).
5. Right-click on the shelf at the bottom of the screen.
6. Go to Shelf -> Contents
7. Then, just scroll around and find ConnMan.
8. and hit Add.

NetworkManager

You can also use networkmanager to manage your network connections. Follow the instructions on NetworkManager to do the configuration.

You probably also need network-manager-applet to help with your settings. You may want to add it to the start up programs so every time Enlightenment starts it appears on systray. For that you should go to Settings Panel > Apps > Startup Applications > System and activate Network.

Whilst network connectivity will work, the applet itself will not be visible without a #System tray.

#### Polkit agent

Enlightenment does not ship with a graphical polkit authentication agent. If you want to access some privileged actions (e.g. mount a filesystem on a system device), you have to install one and autostart it. For that you should go to Settings Panel > Apps > Startup Applications > System and activate it. There is an EFL based authentication agent available in the AUR, polkit-efl-gitAUR.

#### GNOME Keyring integration

It is possible to use gnome-keyring in Enlightenment. However, at the time of writing, you need a small hack to make it work in full. First, you must tell Enlightenment to autostart gnome-keyring. For that you should go to Settings Panel > Apps > Startup Applications > System and activate Certificate and Key Storage, GPG Password Agent, SSH Key Agent and "Secret Storage Service". After this, you should edit your `~/.profile` and add the following:

           #Set gnome-keyring as the ssh authentication agent
           export SSH_AUTH_SOCK=/run/user/${UID}/keyring/ssh

This "hack" is used to override the automatic setting of the variable by "enlightenment-start" from "ssh-agent" to gnome-keyring.

More information on this topic in the GNOME Keyring article.

#### System tray

Note: Since Enlightenment 20, Xembed support has been removed [1] meaning that many 'legacy' applets can no longer be displayed in the Systray. To use these applets, you will need to use a standalone system tray application such as stalonetray instead.

Enlightenment has support for a system tray but it is disabled by default. To enable the system tray, open the Enlightenment main menu, navigate to the Settings submenu and click on the Modules option. Scroll down until you see the Systray option. Highlight that option and click the Load button. Now that the module has been loaded, it can be added to the shelf. Right click on the shelf you wish to add the Systray to, hightlight the Shelf submenu and click on the Contents option. Scroll down until you see Systray. Highlight that option and click the Add button.

#### Notifications

Enlightenment provides a notification server through its Notification extension.

- Notifications may be displayed in any corner of the "screen" as defined below
- Available screen policies are Primary Screen, Current Screen, All Screens, and Xinerama
- Notifications may be filtered based on urgency (Low, Normal, or Critical in any combination)
- A default notification timeout may be set and optionally enforced for all notifications
- The notification server may also optionally ignore replace ID requests

### Themes

More themes to customize the look of Enlightenment are available from:

- exchange.enlightenment.org
- e17-stuff.org
- relighted.c0n.de for the default theme in 200 different colors
- git.enlightenment.org (git clone the theme you like, run 'make' and you end up with a .edj theme file)
- packages.bodhilinux.com has a good collection (you will need to extract the .edj file from the .deb; bsdtar will do this and is part of the base ArchLinux install). A nice catalog can be seen at their wiki.

You can install the themes (coming in .edj format) using the theme configuration dialog or by moving them to `~/.e/e/themes`.

Note: Enlightenment does not provide a stable theme API, and there have been numerous theme API changes over the years, even after E17 was released. Themes that have not been updated regularly are unlikely to work.
Tip: To make GTK and Qt applications match the default theme of Enlightenment you can download a theme like the E17 GTK theme, place it in `~/.themes/` and select application themes from Enlightenments settings, and set it to that, this will make all GTK2 and GTK3 applications match the default Enlightenment theme, you can then configure Qt applications (or configure Qt's default settings) to use the Gtk+ theme so it will mimic the theme your GTK applications are using, this way you can make sure most applications will blend in perfectly with your default enlightenment theme. See also Uniform look for Qt and GTK applications.

#### GTK+

To alter the GTK+ theme, go to Settings > All > Look > Application Theme.

### Modules and Gadgets

Module
  Name used in enlightenment to refer to the "backing" code for a gadget.
Gadget
  Front-end or user interface that should help the end users of Enlightenment do something.

Many Modules provide Gadgets that can be added to your desktop or on a shelf. Some Modules (such as CPUFreq) only provide a single Gadget while others (such as Composite) provide additional features without any gadgets. Note that certain gadgets such as Systray can only be added to a shelf while others such as Moon can only be loaded on the desktop.

#### "Extra" modules

Warning: These are 3rd party modules and not officially supported by the Enlightenment developers. They are also pulled directly from git, so they are development code that may or may not work at any time. Use at your own risk.

Beyond the modules described here, more "extra" modules are available from e-modules-extra-gitAUR.

Places

Places is a gadget that will help you browse files on various devices you might plug into your computer, like phones, cameras, or other various storage devices you might plug into the usb port.

Available from places-gitAUR[broken link: archived in aur-mirror].

Note: This module is no longer required for auto-mounting external devices in Enlightenment

Scale Windows

The Scale Windows module, which requires compositing to be enabled, adds several features. The scale windows effect shrinks all open windows and brings them all into view. This is known in "Mission Control" in macOS. The scale pager effect zooms out and shows all desktops as a wall, like the compiz expo plugin. Both can be added to the desktop as a gadget or bound to a key binding, mouse binding or screen edge binding.

Some people like to change the standard window selection key binding `ALT + Tab` to use Scale Windows to select windows. To change this setting, you navigate to Menu > Settings > Settings Panel > Input > Keys. From here, you can set any key binding you would like.

To replace the window selection key binding functionality with Scale Windows, scroll through the left panel until you find the ALT section and then find and select `ALT + Tab`. Then, scroll through the right panel looking for the "Scale Windows" section and choose either Select Next or Select Next (All) depending on whether you would like to see windows from only the current desktop or from all desktops and click Apply to save the binding.

Available from comp-scale-gitAUR[broken link: archived in aur-mirror].

### Default Keybindings

Some default Enlightenment keybindings
Shift + F10 | Maximize Vertically
Ctrl + Menu | Show "Clients" (windows) Menu
Alt + Escape | Show "Everything Launcher" (apps, windows, etc)
Win + Left | Maximize Left
Win + Right | Maximize Right
Alt + Shift + F10 | Maximize Horizontally
Alt + Shift + Left | Flip to the Desktop on the Left
Alt + Shift + Right | Flip to the Desktop on the Right
Ctrl + Alt + D | Show the desktop
Ctrl + Alt + F | Toggle Fullscreen
Ctrl + Alt + I | Toggle iconic mode
Ctrl + Alt + K | Kill window
Ctrl + Alt + L | Lock the desktop
Ctrl + Alt + N | Maximize Window
Ctrl + Alt + R | Toggle Shade up
Ctrl + Alt + W | Window menu
Ctrl + Alt + X | Close a window

Ctrl + Alt + Up | Raise
Ctrl + Alt + Left | Flip to desktop on left
Ctrl + Alt + Right | Flip to desktop on right
Ctrl + Alt + Delete | End session dialog
Ctrl + Alt + Insert | Launch the default terminal

### Troubleshooting

If you find some unexpected behavior, there are a few things you can do:

1. try to see if the same behavior exists with the default theme
2. disable any 3rd party modules you may have installed
3. backup `~/.e` and remove it (e.g. `mv ~/.e ~/.e.back`)

If you are sure you found a bug please report it directly upstream.

#### Compositing

When the configuration needs to be reset and the settings windows can no longer be approached, configuration for the compositor can be reset using the hardcoded keybinding `Ctrl + Alt + Shift + Home`.

#### Unreadable fonts

If fonts are too small and your screen is unreadable, be sure the right font packages are installed. ttf-dejavu and ttf-bitstream-vera are valid candidates.

You can set scaling under Settings > Settings Panel > Look > Scaling.

#### Backlight always dimmed

You may find that Enlightenment routinely dims the backlight to 30% on logout and will only restore it to 100% when you log into another Enlightenment session. This is especially problematic when using another desktop environment alongside Enlightenment as the backlight will not automatically be restored to its normal level when using that desktop environment. To fix this issue, open the Enlightenment Settings Panel and, under the Look tab, click on the Composite option. Tick the Don't fade backlight box and click OK.

#### Inconsistent cursor theme

You may find that the cursor theme for the desktop is different to the one used in applications such as Firefox. This is because desktop applications are using X cursor themes whilst Enlightenment has its own set of cursor themes. For consistency, you can set Enlightenment to always use the X cursor theme. To do this, open the Enlightenment Settings Panel and click on the Input tab. Click on the Mouse option. Change the theme from Enlightenment to X and click OK. You should now find that the same cursor theme is used everywhere. If the X cursor theme itself is not always consistent, see Cursor themes#XDG specification.

#### Background images

You have to copy the desired wallpapers into `~/.e/e/backgrounds/`

MMB or RMB anywhere on the desktop will give access to the settings, select `/Desktop/Backgrounds/`

Any new image copied in the `~/.e/e/backgrounds/` folder will get the list of available backgrounds auto-updated. Select desired wallpaper from drop-down menu. Inside the appropriate tabs in the global settings, you can adjust things like tiling of the background image, filling screen and such.

## Enlightenment DR16

Enlightenment, Development Release 16 was first released in 2000, and reached version 1.0 in 2009. Originally, the DR16 stood for the 0.16 version of the Enlightenment project. You'll find it as "Enlightenment16" now in the Arch repositories, it is still under development today, regularly updated by its maintainer Kim 'kwo' Woelders. With compositing, shadows and transparencies, E16 kept all of the speed that presided over its foundation by original author Carsten "Rasterman" Haitzler but with up to date refinement.

### To install E16

Install enlightenment16.

See `/usr/share/doc/e16/e16.html` for in depth documentation. The man page is at `man e16`, not `man enlightenment`, and only gives startup options.

### Basic Configuration

Most configuration files for E16 reside in `~/.e16` and are text-based, editable at will. That includes the Menus too.

Shortcut keys can be either modified by hand, or with the e16keyedit software provided as source on the sourceforge page of the e16 project, or from the e16keyeditAUR[broken link: archived in aur-mirror] package. Note that the keyboard shortcuts file is not created in `~/.e16` by default. You can copy the packaged version to your home directory if you wish to make changes:

    $ cp /usr/share/e16/config/bindings.cfg ~/.e16

#### Start/Restart/Stop Scripts

Create an Init, a Start and a Stop folder in your `~/.e16` folder: any .sh script found there will either be executed at Startup (from Init folder), at each Restart (from Start folder), or at Shutdown (from Stop folder); provided you allowed it trough the MMB / settings / session / <enable scripts> button and made them executable with `chmod +x yourscript.sh`. Typical examples involves starting pulseaudio or your favorite network manager applet.

#### Compositor

Shadows, Transparent effects et all can be found in MMB or RMB /Settings, under Composite .
