## Installation of Openbox

### Note

If XORG_PREFIX is not `/usr`, tell gcc about it:

    export LIBRARY_PATH=$XORG_PREFIX/lib

If you only installed the Python 3 PyXDG module convert one of the scripts to Python 3:

    2to3 -w data/autostart/openbox-xdg-autostart &&
    sed 's/python/python3/' -i data/autostart/openbox-xdg-autostart

Install Openbox by running the following commands:

    ./configure --prefix=/usr     \
                --sysconfdir=/etc \
                --disable-static  \
                --docdir=/usr/share/doc/openbox-3.6.1 &&
    make

This package does not come with a test suite.

Now, as the `root` user:

    make install

## Command Explanations

`--sysconfdir=/etc`: This option puts Openbox's configuration files in /etc/xdg/openbox instead of /usr/etc/xdg/openbox.

`--docdir=/usr/share/doc/openbox-3.6.1`: this puts a few files in a versioned directory in `/usr/share/doc`.

`--disable-static`: This switch prevents installation of static versions of the libraries.

## Configuring Openbox

### Config Files

/etc/xdg/openbox/autostart, /etc/xdg/openbox/menu.xml, /etc/xdg/openbox/rc.xml, ~/.config/openbox/autostart, ~/.config/openbox/menu.xml and ~/.config/openbox/rc.xml

### Configuration Information

Openbox's right click menu can be used to launch programs. The menu itself is configured with 2 files, `/etc/xdg/openbox/menu.xml` and `~/.config/openbox/menu.xml`. To make changes to the menu, copy /etc/xdg/openbox/menu.xml to ~/.config/openbox/menu.xml and edit it:

    cp -rf /etc/xdg/openbox ~/.config

`~/.config/openbox/menu.xml` can be edited with a text editor or you can install Obmenu (requires pyxml and PyGTK-2.24.0).

To have icons in your right click menu requires installing imlib2-1.5.1 before you install Openbox. To set an icon for an entry in the menu edit `~/.config/openbox/menu.xml` and add an icon to the <item> tag like this:

    <item label="Mplayer" icon="/usr/share/pixmaps/mplayer.png">

Many other aspects of Openbox's behaviour are configured with `~/.config/openbox/rc.xml` such as what keybindings are used to launch programs or which mouse button launches the main menu.

Details of the theme that Openbox applies to window decorations are configured in `~/.config/openbox/rc.xml`. You can get a list of the available themes with the command:

    ls -d /usr/share/themes/*/openbox-3 | sed 's#.*es/##;s#/o.*##'

### Starting Openbox

To automatically start openbox when you start Xorg:

    echo openbox > ~/.xinitrc

If you want to set a background image to your desktop you can use display and launch it from ~/.xinitrc just before openbox:

    cat > ~/.xinitrc << "EOF"
    display -backdrop -window root /path/to/beautiful/picture.jpeg
    exec openbox
    EOF

Or if you like a bit of variety, put a selection of images in a folder (in this example, the directory ~/.config/backgrounds) and choose one at random each time you xinit:

    cat > ~/.xinitrc << "EOF"
    # make an array which lists the pictures:
    picture_list=(~/.config/backgrounds/*)
    # create a random integer between 0 and the number of pictures:
    random_number=$(( ${RANDOM} % ${#picture_list[@]} ))
    # display the chosen picture:
    display -backdrop -window root "${picture_list[${random_number}]}"
    exec openbox
    EOF

If you like to have the numlock key set whan you start Xorg, install Numlockx and add that to your xinitrc. Another useful application is dbus-1.12.12:

    cat > ~/.xinitrc << "EOF"
    . /etc/profile
    picture_list=(~/.config/backgrounds/*)
    random_number=$(( ${RANDOM} % ${#picture_list[*]} ))
    display -backdrop -window root "${picture_list[${random_number}]}"
    numlockx
    eval $(dbus-launch --auto-syntax --exit-with-session)
    lxpanel &
    exec openbox
    EOF
