From the Enlightenment wiki:

The Enlightenment desktop shell provides an efficient yet breathtaking window manager based on the Enlightenment Foundation Libraries along with other essential desktop components like a file manager, desktop icons and widgets. It boasts a unprecedented level of theme-ability while still being capable of performing on older hardware or embedded devices.

E17 is the development release 17 (DR17) of the Enlightenment Desktop Environment. It 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. E17 has been under development since 2005, but in February 2011 the core EFLs saw their first stable 1.0 release. Enlightenment the window manager is still in the beta stages, but is already quite usable. Many people currently use E17 as a day-to-day desktop environment without problems.

Installing E17

From the community repository (SVN snapshots)

Note: Make sure the community repository is enabled in your Template:Filename.

To install e17:

pacman -S e-svn

To install additional e17 modules and applications:

pacman -S e17-extra-svn

You might also want to install additional Fonts. You need at least 1 True Type Font.

If you need/want an e17 package which is not (yet) available in [community], see if it is available in the AUR.

Warning: As e17 is still alpha software you are encouraged to keep packages of the previous version on your computer, allowing you to downgrade if needed.

Compiling and packaging with ArchE17 script

You can build your own Arch Linux e17 packages with a small python script called ArchE17.

Compiling with easy_e17.sh

Template:Codeline compiles E17 from source and installs it in Template:Filename. It does not create packages and therefore does not install dependencies automatically.

  1. Get it from the AUR: Template:Package AUR.
  2. Edit Template:Filename if you want.
  3. Run it as user, so it downloads to ~/e17_src and builds as user, to install E17 (the script will immediately ask for your password so it can install in the end):
    # easy_e17.sh -i
    Warning: This will install the latest svn version. For a stable result add the --srcrev= parameter with the latest stable revision. For beta 3 use 55246 as argument. For the revision with the 1.0 release of the core libraries, use 56361.
  4. Put Template:Filename in your Template:Codeline by editing Template:Filename. For example, you can add this line at the end of the file:
    PATH="$PATH:/opt/e17/bin"
  5. If, after completing the install, xinitrc complains that it cannot find enlightenment upon starting, you may need to add these lines to the end of /etc/profile as well:
    PYTHONPATH=":$PYTHONPATH"
    LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/opt/e17/lib"

If you encounter any errors while trying to install E17, first check to make sure it is not a dependency problem. If it is, install the dependency and continue installing e17.

To update E17 without using the program mentioned below, run this command as root:

# easy_e17.sh -u

Update_e17.sh

Template:Codeline is a zenity script which is made to accompany Template:Codeline. It makes several aspects of updating e17 easier as it can backup and restore your E17 svn tree (in case there is breakage), as well as roll it back to a specific revision (again, in case of breakage) or even let you know when a new revision has come around on E17's svn tree. See this page for more information on this optional component. You can get it from the AUR: Template:Package AUR.

Starting E17

startx

If you use Template:Codeline or a simple Display Manager like XDM or SLiM, add or uncomment the following command in xinitrc:

exec enlightenment_start

Elsa

Nowadays E17 has a new display manager called Elsa, you can download it from AUR Template:Package AUR. Elsa is quite sophisticated and its configuration is controlled by Template:Filename. To start Elsa add the following line to your Template:Filename

x:5:respawn:/usr/sbin/elsa

and change your default runlevel to 5.

Other

More advanced display managers like GDM and KDM will automatically detect E17 thanks to the Template:Filename file provided by the Template:Codeline package.

Configuring the Network

NetworkManager

You can use Template:Package Official to manage your network connections.

pacman -S networkmanager

Then you need to follow the instructions on NetworkManager to do the configuration. You may also need Template:Package Official to help with your settings.

pacman -S network-manager-applet

You may want to add it to the start up programs so every time your E17 starts it appears on systray.

Settings -> Settings Panel -> Apps -> Startup Applications -> System -> Network

connman

Another available network manager is Connman, you can download it from AUR Template:Package AUR. You do not need to follow any of the other instructions on the Connman wiki page. The current build of ConnMan already includes network policy group section (although with only one statement, not three).

Next, edit your Template:Codeline. Remove network from your DAEMONS line. Add connmand (do not forget the d) after dbus and hal.

ConnMan loads very quickly and appears to handle DHCP quite nicely. If you have installed Wpa_supplicant, ConnMan latches onto that shows all available wireless connections.

Installing Themes

More themes to customize the look of e17 are available from:

You can install the themes (coming in .edj format) from the configuration dialog. During 2010 there was a change in how themes work, so for older themes you may need to do the following:

edje_convert <theme>.edj

Note: the edje_convert binary has been "dropped" by upstream developers... see: trac.enlightenment.org

You can also change the theme for the etk toolkit (the one which is used by exhibit). You can start the dialog to change the etk toolkit by starting Template:Codeline.

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. backup Template:Filename and remove it (e.g. Template:Codeline).

If you are sure you found a bug please report it directly upstream. http://trac.enlightenment.org/e/report

Cursors

If X complains about X cursors not being available, install the Template:Package Official package.

Screen unlocking does not work

If screenlock does not accept your password add the following to Template:Filename:

auth required pam_unix_auth.so

Unreadable fonts

If fonts are too small and your screen is unreadable, be sure the right font packages are installed:

pacman -S ttf-dejavu ttf-bitstream-vera

Modules and gadgets working with HAL

For the purposes of this section I will assume that a module is the backing for a gadget. Many times it seems that a module with the name "Places", for example, will have the same name as a gadget named "Places" which presumably uses that module. Sometimes those modules try to use underlying libraries or daemons to interact with various devices. At the time of this entry the HAL page says,

HAL (Hardware Abstraction Layer) is a daemon that allows desktop applications to readily access hardware information, to locate and use such hardware regardless of bus or device type. In this way a desktop GUI can present all resources to its user in a seamless and uniform manner. HAL has become deprecated in favor of udev, udisks, upower, etc. and is no longer developed. Currently, a small number of programs still rely on and use HAL, though development is heading toward utilizing udev as a replacement.

So, apparently e17 now trys to use udisks instead of hal. But some of the modules and gadgets, such as Places, have not been updated to use udisks yet. So, if you load the "Places" module, and then add the Places gadget to, say, your bottom shelf in enlightenment, it may look something like a blank grey area with no Gadget in it. Not to mention that if you plug a usb device in, the Places module will not detect it. So in order to fix this, here is a "solution":

What is the Places module

From the source code README:

Places module
This module manage the volumes device attached to the system.

Which is an amazing way to say that this is a module or gadget that would 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.

A solution or workaround for "Places"

This procedure will attempt to help you get the Places gadget working on your e17 desktop.

  1. install cower from the AUR
  2. install hal-git ...
    1. cower -d -d hal-git
    2. cd hal-info
    3. makepkg -s
    4. sudo pacman -U hal-info-0.yourBuildDate-1-any.pkg.tar.xz ... NOTE: You may have more dependencies to install here such as the "base-devel" package
    5. cd ../hal-git
    6. makepkg -s
    7. sudo pacman -U hal-git-yourBuildDate-1-x86_64.pkg.tar.xz
  3. start the hal daemon ... # /etc/rc.d/hal start
  4. remove the old Places gadget from my shelf ... right click the Places gadget (which is just a blank area) -> Gedget Places -> Remove
  5. unload the Places module ... left click desktop -> settings -> modules -> Places -> unload
  6. restart enlightenment ... left click desktop -> enlightenment -> restart
  7. reload the Places module ... left click desktop -> settings -> modules -> Places -> load
  8. add the Places gadget to my shelf ... left click shelf -> settings -> gadgets -> Places -> add gadget
  9. plug in a usb camera.
  10. watch it appear as a new device on the shelf inside the Places gadget
  11. Right Click Places -> Gadget Places -> Move to -> Desktop

The Places gadget on the desktop should now look like an icon with a camera plugged into a usb port: And when you click on it, it opens a file manager, and shows you the files on your camera ... imagine that. Hope this helps get the Places module working on your desktop.
