Openbox linux ��� ���

Issues regarding commands in

/.config/openbox/autostart being executed out of order (or skipped altogether) are often resolved by the addition of small delays. For instance:

environment

/.config/openbox/environment can be used to export and set relevant environmental variables such as to:

• Define new pathways (e.g. execute commands that would otherwise require the entire pathway to be listed with them)
• Change language settings, and
• Define other variables to be used (e.g. the fix for GTK theming could be listed here)

Themes

Install obconf and/or lxappearance-obconf for a GUI to configure visual settings and theming.

A good selection of themes are available in the openbox-themes AUR package or the AUR. Some GTK#Themes come with an Openbox theme as well. Both Openbox-specific and Openbox-compatible themes will be installed to the /usr/share/themes directory and will also be immediately available for selection.

box-look.org is an excellent and well-established source of themes. deviantART.com is another excellent resource. Many more can be found online.

Edit or create

The process of creating new or modifying existing themes is covered extensively at the official openbox.org website. obtheme AUR is a user-friendly GUI for doing so.

GUI configuration

Several GUI applications are available to quickly and easily configure your Openbox desktop.

• ObConf — A GTK3 based configuration tool for the Openbox window manager.

Programs and applications relating to the configuration of Openbox’s desktop menu are discussed in the Menus section.

Openbox reconfiguration

Openbox will not always automatically reflect any changes made to its configuration files within a session. As a consequence, it will be necessary to manually reload those files after they have been edited. To do so, enter the following command:

Where intending to add this command as a keybind to

/.config/openbox/rc.xml , it will only be necessary to list the command as reconfigure . An example has been provided below, using the Super + F11 keybind:

Keybinds

All keybinds must be added to the

/.config/openbox/rc.xml file, and below the heading. Although a brief overview has been provided here, a more in-depth explanation of keybindings can be found at openbox.org.

Keybinds can be added to the configuration file using the following syntax:

The action name for running an external command is Execute. Use the following syntax to define an external command to execute:

See the Openbox wiki for a list of all available actions.

While the use of standard alpha-numeric keys for keybindings is self-explanatory, special names are assigned to other types of keys, such as modifiers , multimedia and navigation .

Modifiers

Modifier keys play an important role in keybindings (e.g. holding down the shift or CTRL / control key in combination with another key to undertake an action). Using modifiers helps to prevent conflicting keybinds, whereby two or more actions are linked to the same key or combination of keys. The syntax to use a modifier with another key is:

The modifier codes are as follows:

• S : Shift
• C : Control / CTRL
• A : Alt
• W : Super / Windows
• M : Meta
• H : Hyper (If it is bound to something)

Multimedia keys

Where available, it is possible to set the appropriate multimedia keys to perform their intended functions, such as to control the volume and/or the screen brightness. These will usually be integrated into the function keys, and are identified by their appropriate symbols. See Extra keyboard keys for details.

The volume and brightness multimedia codes are as follows (note that commands will still have to be assigned to them to actually function):

• XF86AudioRaiseVolume : Increase volume
• XF86AudioLowerVolume : Decrease volume
• XF86AudioMute : Mute / unmute volume
• XF86MonBrightnessUp : Increase screen brightness
• XF86MonBrightnessDown : Decrease screen brightness

For a full list of XF86 multimedia keys, see LQWiki:XF86 keyboard symbols.

Volume control

What commands should be used for controlling the volume will depend on whether ALSA, PulseAudio, or OSS is used for sound.

Navigation keys

These are the directional / arrow keys, usually used to move the cursor up, down, left, or right. The (self-explanatory) navigation codes are as follows:

• Up : Up
• Down : Down
• Left : Left
• Right : Right

Menus

It is possible to employ three types of menu in Openbox: static , pipes (dynamic), and generators (static or dynamic). They may also be used alone or in any combination.

Static

As the name would suggest, this default type of menu does not change in any way, and may be manually edited and/or (re)generated automatically through the use on an appropriate software package.

Fast and efficient, while this type of menu can be used to select applications, it can also be useful to access specific functions and/or perform specific tasks (e.g. desktop configuration), leaving the access of applications to another process (e.g. the synapse or xfce4-appfinder applications).

/.config/openbox/menu.xml file will be the sole source of static desktop menu content.

menumaker

menumaker automatically generates xml menus for several window managers, including Openbox, Fluxbox, IceWM and Xfce. It will search for all installed executable programs and consequently create a menu file for them. It is also possible to configure MenuMaker to exclude certain application types (e.g. relating to GNOME or KDE), if desired.

Once installed and executed, it will automatically generate a new

/.config/openbox/menu.xml file. To avoid overwriting an existing file, enter:

Otherwise, to overwrite an existing file, add the force argument ( f ):

/.config/openbox/menu.xml file has been generated it may then be manually edited, or configured using a GUI menu editor, such as obmenu AUR .

obmenu

obmenu AUR is a «user-friendly» GUI application to edit

/.config/openbox/menu.xml , without the need to code in xml .

xdg-menu

archlinux-xdg-menu will automatically generate a menu based on xdg files contained within the /etc/xdg/ directory for numerous Window Managers, including Openbox. Review the Xdg-menu#OpenBox article for further information.

logout menu options

/.config/openbox/menu.xml file can be edited in order to provide a sub-menu with the same options as provided by oblogout. The sample script below will provide all of these options, with the exception of the ability to lock the screen:

Once the entries have been composed, add the following line to present the sub-menu where desired within the main desktop menu (usually as the last entry):

Pipes

This type of menu is in essence a script that provides dynamic, refreshed lists on-the-fly as and when run. These lists may be used for multiple purposes, including to list applications, to provide information, and to provide control functions. Pre-configured pipe menus can be installed, although not from the official repositories. More experienced users can also modify and/or create their own custom scripts. Again,

/.config/openbox/menu.xml may and commonly will contain several pipe menus.

Examples

• openbox-xdgmenuAUR : fast xdg-menu converter to xml-pipe-menu
• obfilebrowserAUR : Application and file browser
• obdevicemenuAUR : Management of removable media with Udisks
• wifi pipe menu: Wireless networking using Netctl

Openbox.org also provides a further list of pipe menus.

Generators

This type of menu is akin to those provided by the taskbars of desktop environments such as Xfce or LXDE. Automatically updating on-the-fly, this type of menu can be powerful and very convenient. It may also be possible to add custom categories and menu entries; read the documentation for your intended dynamic menu to determine if and how this can be done.

A menu generator will have to be executed from the

obmenu-generator

obmenu-generator AUR is highly recommended despite being an unofficial package. With the ability to be used as a static or dynamic menu, it is highly configurable, powerful, and versatile. Menu categories and individual entries may also be easily hidden, customised, and/or added with ease. The official homepage provides further information and screenshots.

Below is an example of how obmenu-generator would be dynamically executed without icons in

To automatically iconify entries, the -i option would be added:

openbox-menu

openbox-menu AUR uses the LXDE menu-cache to create dynamic menus. The official homepage provides further information and screenshots.

Menu icons

To show icons next to menu entries, it will be necessary to ensure they are enabled in the section of the

Where using a static menu, it will then be necessary to edit the

/.config/openbox/menu.xml file to provide both the icon = command, along with the full path and icon name for each entry. An example of the syntax used to provide an icon for a category is:

Desktop menu as a panel menu

xdotool is a package that can issue commands to simulate key presses / keybinds, meaning that it is possible to use it to invoke keybind-related actions without having to actually press their assigned keys. As this includes the ability to invoke an assigned keybind for the Openbox desktop menu, it is therefore possible to use XDoTool to turn the Openbox desktop menu into a panel menu. Especially where the desktop menu is heavily customised and feature-rich, this may prove very useful to:

• Replace an existing panel menu
• Implement a panel menu where otherwise not provided or possible (e.g. for Tint2)
• Compensate where losing access to the desktop menu due to the use of an application like xfdesktop to manage the desktop.

Once XDoTool has been installed — if not already present — it will be necessary to create a keybind to access the root menu in

/.config/openbox/rc.xml , and again below the heading. For example, the following code will bring up the menu by pressing CTRL + m :

Openbox must then be reconfigured. In this instance, XDoTool will be used to simulate the CTRL + m keypress to access the desktop menu with the following command (note the use of + in place of — ):

How this command may be used as a panel launcher / icon is largely dependent on the features of panel used. While some panels will allow the above command to be executed directly in the process of creating a new launcher, others may require the use of an executable script. As an example, a custom executable script called obpanelmenu.sh will be created in the

Once the empty file has been opened, the appropriate XDoTool command must be added to the empty file (i.e. to simulate the CTRL + m keypress for this example):

After the file has been saved and closed, it may then be made into an executable script with the following command:

Executing it will bring up the Openbox desktop menu. Consequently, where using a panel that supports drag-and-drop functionality to add new launchers, simply drag the executable script onto it before changing the icon to suit personal taste.

XDG compliant menu

A xdg compliant menu is based on the freedesktop.org standard. The menu is defined in menu-files which reside in /etc/xdg/menus. New applications will occur automatically in the menu.

Examples

• californium: xdg menu based on the LXQt main menu and easily themable

Tips and tricks

Cursor and icon themes

See Cursor themes and Icons for details.

Desktop icons and wallpapers

Openbox does not natively support the use of desktop icons or wallpapers.

/.conkyrc and set own_window_type to normal .

Compositing effects

Openbox does not provide native support for compositing, and thus requires an external compositor for this purpose.

Although compositing is not a necessary component, it may specifically avoid issues such as screen distortion with oblogout, and visual glitches with terminal window transparency. See Xorg#Composite for common choices.

oblogout

See the Oblogout article for an overview on how to use this useful, graphical logout script.

Openbox for multihead users

While Openbox provides better than average multihead support on its own, openbox-multihead-git AUR provides a development branch called Openbox Multihead that gives multihead users per-monitor desktops. This model is not commonly found in floating window managers, but exists mainly in tiling window managers. It is explained well on the Xmonad web site. Also, please see README.MULTIHEAD for a more comprehensive description of the new features and configuration options found in Openbox Multihead.

Openbox Multihead will function like normal Openbox when only a single head is available.

Launch a complex command with hotkey

If you need to execute a complex command, use shell functionality.

When writing your own scripts, make sure to escape xml special characters, such as » & » («&»), » » (» > » («>») and other (see more on Predefined entities in XML).

This example will turn off display immediately and lock screen with slock . It was taken from this thread.

Sometimes one need to specify environment variable for application:

Another example will launch application preserving all stdout and stderr output to file:

Application launchers

Given the lack of a desktop environment with a plain Openbox install, it can be useful to install one or more application launchers as supplements to the Openbox menu system and the hotkeys. Lists of such launchers can be found at Category:Application launchers and List of applications/Other#Application launchers; popular examples are Gmrun and dmenu.

Switch desktops using the mouse

It is possible to switch desktop by moving the mouse cursor to the edges of the screen. First install xdotool and add the following two lines to your

Set default applications / file associations

Ad-hoc window transparency

The program transset-df AUR can enable window transparency on-the-fly.

For example, using the following code in the section of the

/.config/openbox/rc.xml file will enable control of application window transparency by hovering the mouse-pointer over the title bar and scrolling with the middle button:

Using obxprop for faster configuration

The openbox package provides a obxprop binary that can parse relevant values for applications settings in rc.xml . Officially obxprop | grep «^_OB_APP» is recommended for this task. Start the process by running the command shown, then click a window to see its properties in the terminal.

Xprop values for applications

xorg-xprop can be used to relay property values for selected applications. Where frequently using per-application settings, the following Bash Alias may be useful:

To use Xorg-XProp, run using the alias given xp , and click on the active program desired to define with per-application settings. The results displayed will only be the information that Openbox itself requires, namely the WM_WINDOW_ROLE and WM_CLASS (name and class) values:

Switching between keyboard layouts

See the article section switching between keyboard layouts for instructions.

Set grid layout for virtual desktops

Install obsetlayout AUR . To set a 2×2 grid for example:

Run it without arguments to know what the arguments mean.

Enable Hot Corners

lead provides hot corners for openbox and other lightweight window managers. Start the application with a entry in the autostart-file:

Commands can be edited in the configuration file

Window snapping

Many desktop environments and window managers support window snapping (e.g. Windows 7 Aero snap), whereby they will automatically snap into place when moved to the edge of the screen. This effect can also be simulated in Openbox through the use of keybinds on focused windows.

As illustrated in the example below, percentages must be used to determine window sizes (see openbox.org for further information). In this instance, The super key is used in conjunction with the navigation keys:

However, it should be noted that once a window has been ‘snapped’ to an edge, it will remain vertically maximised unless subsequently maximised and then restored. The solution is to implement additional keybinds — in this instance using the down and up keys — to do so. This will also make pulling ‘snapped’ windows from screen edges faster as well:

This Ubuntu forum thread provides more information. Applications such as opensnap AUR are also available to automatically simulate window snapping behaviour without the use of keybinds. Another option is to use bunsen-utilities-git AUR which provides bl-aerosnap —left and bl-aerosnap —right commands which will snap active window on left or right edge respectively if it’s not snapped and restore it to original size and position otherwise. Just bind these commands to the key combination of your choosing.

Smooth display manager transition

Users of display managers might experience a flickering during the transition between the display manager and the Openbox desktop. The flickering comes from Openbox setting the root window’s color during startup. Therefore there is a brief moment when the display flashes in a grey color, between the display manager’s background and the desktop’s wallpaper.

Setting the root window’s background color can be disabled by editing the Openbox startup script found in /usr/lib/openbox/openbox-autostart . Simply comment out (or delete) the block starting with # Set a background color .

Window Decorations

To remove window decorations for all or particular applications, use the option in the section of rc.xml (user:

/.config/openbox/ or system: /etc/xdg/openbox/).
Example for Firefox, including variants like Firefox-Beta and Firefox-Nightly:

One could also disable decorations for all applications (using class «*»), then enable them (using yes) for individual ones. To apply the changes, restart your desktop session, and thus Openbox. Reference: Openbox FAQ

Troubleshooting

Firefox

Mozilla based browsers may ignore application rules (e.g. ) unless class=»Firefox» is used. See #Xprop values for applications.

Missing themes

If for any reason the newly extracted theme cannot be selected, open the theme directory to first ensure that it is compatible with Openbox — there should be an openbox-3 directory and a themerc file within it. An .obt (OpenBox Theme) file may also be present in some instances, which can then be manually loaded in obconf .

A theme may also be not accessible due to wrong permissions. See File permissions and attributes for more.

Stop continuous desktop switching

By default Openbox switches from the last desktop back to the first desktop on mouse wheel scroll. Use no in the mousebind section to disable this behaviour.

Windows load behind the active window

Some application windows (such as Firefox windows) may load behind the currently active window, causing you to need to switch to the window you just created to focus it. To fix this behavior add this to your
