A Window Manager designed for speed, usability, and consistency


wonderful Win95-OS/2-Motif-like window manager


 icewm - lightweight X11 window manager


icewm [OPTIONS]


icewm is a lightweight window manager for the X11 window system. It aims to be small, fast and familiar to new users. icewm is called a re-parenting window manager, because it draws small frames around application windows. Windows are manipulated via the mouse by dragging or resizing this frame. It is also called a stacking window manager, because windows can overlap. Many windows may exist, some hidden behind others, while interaction takes place with the currently visible ones. icewm supports a configurable number of virtual desktops. It provides a task bar for monitoring applications and a pager to switch between desktops. icewm is largely compliant with the ICCCM 2.0, WinWM/WMH and NetWM/EWMH window manager specifications.
icewm was originally designed to emulate the look of Motif, OS/2 Warp 4, OS/2 Warp 3 and Windows 95. Since it has a theme engine other styles are possible. The installation comes with several configured themes. A menu allows to choose between themes.
Generally, it tries to make all functions available by both keyboard and mouse. Configuration is very good through various preferences files. However, configuring is not required: it works fine out of the box.


The icewm package includes several programs:
icewm(1) The actual window manager. It positions application windows on screen and decorates them with borders. It gives input focus to the current active application. icewm supports different focus modes, which are explained below. It draws a small task bar at the bottom of the screen, which gives easy access to programs, to virtual desktops, to active applications, and to a small set of monitoring applets.
icewmbg(1) The background setting application. It can assign plain background color or images in different formats to the X background. Each work space can have its own background. It supports semi-transparency. Semitransparent background image and colour can be configured. When the background image has changed then icewmbg(1) can be notified to update the background. Multi-head monitor setups are fully supported. This program should be started before icewm. See the icewmbg(1) man page for details.
icewm-session(1) icewm-session(1) is the preferred program to start the IceWM system. It first loads additional environment variables from the optional env file. Then it starts icewmbg(1) and icewm. It also runs the startup script and implements basic session management. On termination the shutdown script will be run first, then icewm-session(1) will terminate icewm and icewmbg(1). icewm-session(1) will also start the optional icesound(1) if you give it the --sound option. See icewm-session(1).
icesh(1) A powerful tool to control window properties and to interact with the window manager. It is typically used in shell scripts. See icesh(1).
icehelp(1) A small document browser, which is used by icewm to display the ’IceWM manual’ and some man pages.
icewmhint(1) A utility for passing IceWM-specific window options to icewm. The options are used to configure the first application which is started subsequently. See icewmhint(1).
icesound(1) Plays audio files on GUI events which are raised by icewm. It supports ALSA, AO and OSS. See the icesound(1) man page.
icewm-menu-fdo(1) Generate an icewm menu with executable desktop applications according to XDG specifications. See the icewm-menu-fdo(1) man page.
icewm-set-gnomewm(1) Configures GNOME to start IceWM instead of its own WM.



Each of the IceWM executables supports the following options:
-c, --config=FILE Use FILE as the source of configuration options. By default icewm looks for a file named preferences. Typically this file is stored as one of $ICEWM_PRIVCFG/preferences, $XDG_CONFIG_HOME/icewm/preferences, or $HOME/.icewm/preferences, or in one of the configuration directories explained below. It contains a long list of options which allow the user to tweak the behaviour of icewm to ones taste. A default preferences file contains comments about the purpose of each option, the range of useful values and the current or default value. A preferences file is a readable text file which can be modified with the help of a text editor. If this option is given to icewm-session(1) then it is passed on to icewm. If icewm is started independently then this option can be given to icewm directly. However, usually one will want to use a preferences file from a default location.
-t, --theme=NAME Use NAME as the name of the icewm theme to use. A theme defines the look and feel of icewm, like colours, fonts, buttons and button behaviour. Originally a theme defined options to emulate the appearance of other desktop environments, like Motif, OS/2 Warp, or Windows. Over the years many new original themes have been designed with beautiful icons and backgrounds, which advance the state of the art in desktop look and feel. Many of them can be downloaded from the website <> and stored in one of the directories $ICEWM_PRIVCFG/icewm/themes/, $XDG_CONFIG_HOME/icewm/themes/ or in $HOME/.icewm/themes/. You can then activate such a theme via the menu in the lower left corner of the display. A default theme is specified in one of $ICEWM_PRIVCFG/icewm/theme, $XDG_CONFIG_HOME/icewm/theme, or in $HOME/.icewm/theme. When a new theme is selected then this value is overwritten, so that the next time icewm is started this choice is reused.
--display=DISPLAY DISPLAY specifies the connection to the X11 server. If this option is missing, as is usually the case, then DISPLAY is read from the environment variable DISPLAY.
--sync This option is sometimes used in software development of icewm. It specifies to use a slower synchronous communication mode with the X11 server. This is irrelevant for normal use of icewm.
-h, --help Gives a complete list of all the available command line options with some very brief explanation.
-V, --version Shows the software release version for this program.


The icewm program supports some additional options:
-a, --alpha Use a 32-bit visual for translucency. This can also be set in the preferences file as Alpha=1.
--replace Instructs icewm to replace an existing window manager. Provided that the window manager being replaced is ICCCM 2.0 compliant, once it notices that it is to be replaced it will cease operations and typically stop execution. This allows icewm to establish itself as the only active window manager.
-r, --restart Tell icewm to restart itself. This reloads the configuration from file.
-s, --splash=IMAGE Briefly show IMAGE on startup in the center of the screen. This can also be set in the preferences file as Splash=image.jpg.
--configured Shows a list of configuration options which were enabled when icewm was compiled from source code. This can be helpful if one suspects some functionality may be missing.
--directories Gives a list of directories where icewm will look for configuration data. This list is printed in the actual order in which icewm uses it to search for configuration files.
-l, --list-themes icewm will search all the configuration directories for theme files and print a list of all found themes.
-p, --postpreferences This gives a long list of all the internal icewm options with their actual values after icewm has processed all of the configuration and theme files. In some advanced scenarios this can be helpful to inspect which configuration was chosen or whether option formatting was correct.
--extensions Give a list of the current X extensions, their versions and status.
--trace=conf,icon,prog Enable tracing of the paths which are used to load configuration, and/or icons, and/or executed programs.



On startup icewm launches the task bar at the bottom of the screen. The task bar consists from left to right of the following components:
The Menu button in the lower left corner gives access to the icewm root menu. This menu has sub-menus to start applications, to control icewm settings, and the icewm Logout menu.
The Show Desktop button unmaps all application windows to fully uncover the desktop.
The Window List Menu button gives access to a menu with a list of active windows for the current work space and a list of work spaces with sub-menus for their active application windows.
The Toolbar is a list of icons for applications which are defined in the toolbar configuration file.
The Workspace List shows one button for each work space. The current work space is indicated by a pressed button. Pressing another work space button switches to that work space. The work spaces are defined in the preferences file. When PagerShowPreview is turned on a small graphical summary for each workspace is shown.
The Task Pane consists of a list of wide buttons for each application which is running on the current work space, or all workspaces if TaskBarShowAllWindows=1. Each task button shows the application icon and the application title. The active application is indicated by a pressed button. This is the application which has input focus. Pressing another button activates that application: it is brought to the foreground and receives input focus. Other mouse controlled activities on the window buttons are: dragging window buttons with the left mouse button to rearrange the order, closing the application window with Alt + middle button, lowering the application window with Ctrl + middle button, or bringing the application window to the current workspace with Shift + middle button if TaskBarShowAllWindows=1.
If there are not many application buttons then a stretch of plain task bar is visible. Clicking on it with the right mouse button gives the task bar menu. Even with a full task pane, this menu can be usually accessed by right-clicking the bottom right corner of the taskbar.
The Tray Applet shows system tray objects.
The APM Applet shows battery power status.
The Net Applet shows network activity. Network devices to monitor are given by the NetworkStatusDevice option.
The Memory Applet monitors memory usage.
The CPU Applet monitors processor utilization.
The Mailbox Applet monitors mailbox status changes. The location of the mailbox is given by the MailBoxPath preferences option or else by the MAILPATH or MAIL environment variables. It can be the path of a local mail spool file or the specification of a remote POP3 or IMAP location. For example:

The Clock Applet shows the current time and date. It is configured by the TimeFormat option.
The Task Bar Collapse button collapses the task bar and hides it.
Not all icewm applets may show up on the task bar. They must have been enabled during configuration of the icewm software. Their appearance is also controlled by options in the preferences file.


Of all visible windows only one can be the active window. This is the window which has input focus. It is the primary receiver of keyboard and mouse events and hence one can interact with the application which created that window. A primary task of a window manager is to allow the user to switch input focus between different windows. The primary means to do this is the mouse pointer. By moving the mouse pointer over the screen to another window, and perhaps also by clicking on a window, input focus can be directed.
The FocusMode option controls the way icewm gives input focus to applications. It is initialized by the focus_mode configuration file. The focus mode is set via the Focus menu. icewm supports six focus models:
1. Click-to-focus The default focus mode. In this mode changing input focus requires to click a window with the left mouse button. The window is raised if needed. When an application requests focus its task pane button flashes. This gives the option to honor this request or to ignore it. When a new application window appears it automatically receives focus. Also when a hidden application raises to the front it receives focus.
2. Sloppy-mouse-focus Sets input focus merely by moving the mouse pointer over a window. It is called sloppy, because if the mouse then leaves the window and moves to the desktop background the input focus remains with the last active window. When a window receives focus it is raised. When an application requests focus its task pane button flashes. A new application or an application which raises to the front automatically receives focus.
3. Explicit-focus Focus is even more user-controlled than Click-to-focus. When a window receives focus it is not raised by default, unless the frame border is clicked. No flashing occurs when an application requests focus. When a new application window appears it does not receive focus. Only by explicit clicking on a window is focus directed.
4. Strict-mouse-focus Like Sloppy but focus remains with the last window. New applications don’t receive focus and are mapped behind other windows. When an application raises to the front it still does not get focus.
5. Quiet-sloppy-focus Like Sloppy but no disturbing flashing occurs on the task bar when an application requests focus.
6. Custom-mode A focus mode which is defined in detail by ten options in the preferences file. These are: ClickToFocus, FocusOnAppRaise, RequestFocusOnAppRaise, RaiseOnFocus, RaiseOnClickClient, FocusChangesWorkspace, FocusOnMap, FocusOnMapTransient, FocusOnMapTransientActive, MapInactiveOnTop.
All non-Custom focus modes override these ten options.
Apart from the mouse, icewm supports changing input focus in two other ways. Both involve the keyboard. The first uses the QuickSwitch window. It is activated by pressing Alt+Tab or Alt+Shift+Tab. A window pops up in the centre of the screen with a narrow band over the next or previous window which will receive input focus when the Alt key is released. By repeatedly pressing Alt+Tab or Alt+Shift+Tab one can cycle through all windows.
The second keyboard method involves pressing Alt+Esc or Alt+Shift+Esc. Input focus is immediately changed to the next or previous window, which will be raised to make it fully visible.
And finally, there is another way which is a hybrid of keyboard and mouse control. It involves the QuickSwitch popup explained before, after pressing Alt+Tab and while still holding Alt a left click on one of the list items causes the activation of the related window.


A second important task of a window manager is to place new windows on the screen. By default icewm chooses a placement with minimal overlap, but this is determined by the SmartPlacement option in the preferences file. If SmartPlacement is turned off then windows are placed in sequence from left to right and top to bottom. One can also turn on ManualPlacement. Then new windows appear initially in the top left corner and the mouse cursor changes into a fist. By moving the fist cursor to a suitable location and clicking the new window will appear at the mouse click location.


Windows can overlap. Which window appears on top is determined by three features. Newer windows appear over older windows. By clicking on a window it is raised to the top. But both are overruled by the window layer. Windows can be placed in different layers via the Layers menu. Click with the right mouse button on the window frame and select Layer. From there choose one of seven window layers. These are ordered from higher to lower. Windows in higher layers appear over windows in lower layers.


icewm supports multiple virtual desktops called work spaces. A work space is like a screen where a subset of all application windows are mapped. Thanks to multiple work spaces we can more easily manage a large number of applications. The number of work spaces and their names are configurable in the preferences file through the WorkspaceNames option. By default four workspaces are created with the names 1, 2, 3 and 4 thus:

 WorkspaceNames=" 1 ", " 2 ", " 3 ", " 4 "
This syntax is typical for icewm options which receive multiple values. It is a list of comma separated values each of which can be quoted.
The work spaces are visible on the toolbar. One can switch to a different work space by pressing the work space button in the toolbar, but after becoming familiar with the ’keyboard shortcuts’ below one will want to use a hotkey to choose a work space. If the EdgeSwitch options is enabled in the preferences file (with sub-options HorizontalEdgeSwitch and VerticalEdgeSwitch) then one can move to the next or previous workspace by moving the mouse to the edge of the screen. The ContinuousEdgeSwitch option enables continuous movement to subsequent workspaces. The EdgeSwitchDelay option says how long to wait before a change of workspace occurs.
To move an application window to a different work space one can use a keyboard shortcut. Another option is to select the Move To submenu in the window menu of the window frame.


If EnableAddressBar=1 then KeySysAddressBar=Alt+Ctrl+Space activates the address bar in the task bar. If ShowAddressBar=1 it is always shown. This is a command line in the task bar where a shell command can be typed. Pressing Enter will execute the command. AddressBarCommand=/bin/sh will be used to execute the command. On Control+Enter the command is executed in a terminal as given by TerminalCommand. The address bar maintains a history which is navigable by the Up and Down keys. It supports file completion using Tab or Ctrl+I. A rich set of editing operations is supported, including cut-/copy-/paste-operations.


The window list window shows a list of all workspaces. For each workspace it shows the window titles of the windows which are mapped on it. The bottom entry reads All Workspaces. It holds the sticky windows. These windows are mapped in all workspaces.
The window list window is normally hidden. Choose one of the following four methods to make it visible:
o Select the bottom window list menu entry.
o Press the KeySysWindowList=Ctrl+Alt+Esc key.
o Press the right Windows key if Win95Keys=1
o Press the DesktopWinListButton=2 mouse button in the root window.
A single-click on a window entry selects it. A group of windows can be selected by Shift+Pointer_Button1 or by dragging with the left mouse button. Use Ctrl+Pointer_Button1 to individually select windows in a multi-selection. A right mouse click over a selection will popup the system menu for this selection. To close the selected windows, press Delete. Press Shift+Delete to forcefully kill them. Right mouse click below the sticky windows for a menu with window arranging actions.
Double-click on a workspace to switch to it. Double-click on a window to activate it. Or navigate by arrow keys and press Enter. The space bar toggles a selection of a window. Ctrl+a and Ctrl+/ will select the entire list of windows. Ctrl+\\ deselects everything. Press the first letter of a window title to navigate to it and select it. If titles of multiple windows start with the same letter then repeatedly pressing the first letter cycles over those windows. Home selects the first entry and End the last. PageUp and PageDown move up or down by ten entries. Combine this with the Shift key to extend a selection over the range of motion.


icewm supports a large number of hotkeys to activate some behaviour with a single key combination. These are all configurable in the preferences file. Here we give their default values, followed by their preferences names and short descriptions of their effect:

You can control windows by a modified mouse button press:
Alt+Pointer_Button1 MouseWinMove moves the window under the mouse over the screen.
Alt+Pointer_Button3 MouseWinSize resizes the window. Keep the key and button pressed. To enlarge the window move the mouse button away from the center. To shrink it move towards the centre.
Ctrl+Alt+Pointer_Button1 MouseWinRaise raises the window under the mouse.
Ctrl+Alt+Pointer_Button1 MouseWinLower lowers the window under the mouse. If this is equal to MouseWinRaise and the window can be raised then MouseWinRaise takes preference over MouseWinLower.
Clicking on the desktop activates a menu. The middle button shows the window list (DesktopWinListButton=2). The right button shows the root menu (DesktopMenuButton=3).
The title frame of a window also listens for mouse clicks. Left double clicking maximizes the window (TitleBarMaximizeButton=1). Middle double clicking rolls up the window (TitleBarRollupButton=2). Pressing a mouse button and moving it will move the window. Alt+left button lowers the window.
When the mouse is on the window frame then a left click raises the window. Dragging with the left button down resizes the window. Clicking the right button pops up the context menu. Dragging with the right button moves the window.


icewm supports the following signals:
SIGHUP icewm will restart itself. It is a way to reload the configuration.
SIGINT, SIGTERM icewm will cease to manage application windows and terminate.
SIGQUIT icewm will initiate the logout procedure. If a LogoutCommand preferences option was configured it will be executed.


ICEWM_PRIVCFG The directory for user private configuration files. When this environment variable is not specified, the default directory is $XDG_CONFIG_HOME/icewm when that directory exists, otherwise the default value is $HOME/.icewm.
DISPLAY The name of the X11 server. See Xorg(1) or Xserver(1). This value can be overridden by the --display option.
MAILPATH, MAIL Gives the location of your mailbox. If the schema is omitted the local file schema is assumed. This is used by the mailbox applet in the task bar to show the status of your mailbox. If the MailBoxPath option in the preferences file is set, then that one takes precedence.


icewm looks for configuration files in the following directories, in the given order, until it finds one:
$ICEWM_PRIVCFG/ Contains user-specific configurations. When ICEWM_PRIVCFG is specified, this directory takes precedence over $XDG_CONFIG_HOME/icewm and $HOME/.icewm.
$XDG_CONFIG_HOME/icewm/ Contains user-specific configurations. When this directory exists it take precedence over $HOME/.icewm.
$HOME/.icewm/ Contains user-specific configurations. This is the historical default directory.
/etc/icewm/ Contains system-wide customized defaults. Please note that your local installation may have been configured to use a different system location. The output of icewm --directories will show this location.
/usr/share/icewm/ Default local installation settings.


env icewm-session(1) loads additional environment variables from the file env. Each line is subjected to POSIX shell expansion by wordexp(3). Comment lines starting by a hash-sign (#) are ignored. icewm-session(1) will load those expanded lines which contain a name, followed by an equals sign, followed by the value (which may be empty).
focus_mode Defines the initial value for FocusMode. Its default value is FocusMode=1 (Click-to-focus). This can be changed via the menu. icewm will save the Focus menu choice in this file.
keys Global keybindings to launch applications, which need not be window manager related. Each non-empty line starts with the word key. After one or more spaces follows a double-quoted string of the bound X11 key combination like Alt+Ctrl+Shift+X. Then after at least one space follows a shell command line which will be executed by icewm whenever this key combination is pressed. For example, the following line creates a hotkey to reload the icewm configuration:

 key "Ctrl+Shift+r"      icesh restart
menu A menu of applications; usually customized by the user. icewm provides the icewm-menu-fdo(1) program to generate a default menu. Similar programs are xdg_menu(1), mmaker(1) (MenuMaker), xde-menu(1), xdgmenumaker(1).
preferences Contains general settings like paths, colors and fonts, but also options to control the icewm focus behaviour and the applets which are started in the task bar. The icewm installation will provide a default preferences file, which can be copied to the icewm user configuration directory and modified.
prefoverride Settings which override the settings from a theme. Some of the icewm configuration options from the preferences file which control the look-and-feel may be overridden by the theme, if the theme designer thinks this is desirable. However, this prefoverride file will again override this for a few specific options of your choosing. It is safe to leave this file empty initially.
programs An automatically generated menu of applications. This could be used by wmconfig(1), menu or similar programs to give easy access to all the desktop applications which are installed on the system.
theme This file contains the name of the default theme. On startup icewm reads this file to obtain the theme name, unless icewm was started with the --theme option. Whenever a different theme is selected from the icewm Menu then the theme file is overwritten with the name of the selected theme. This theme file contains the keyword Theme, followed by an equals sign, followed by a double-quoted string with the theme name. The theme name is the name of the theme directory, followed by a slash, followed by the theme file. Usually the theme file is just default.theme, but a theme may have alternatives. Alternatives are small tweaks of a theme. These are specified in their own .theme file, which replaces default.theme. If no theme file exists then icewm will use the default setting of Theme="default/default.theme".
toolbar Contains names of quick to launch applications with icons for the task bar. Each non-empty non-comment line starts with the keyword prog. After one or more spaces follows a name, which is displayed in a tool tip whenever the mouse cursor hovers over the toolbar icon. This name may be a double quoted string. Then follows the bare name of the icon to use without extensions. This icon will be shown in the toolbar. The last component is a shell command line which will be executed whenever the user presses the icon in the toolbar. For example, the following line in toolbar will create a button with tool tip Mozilla Firefox with the firefox icon which launches firefox(1) when clicked:

 prog  "Mozilla Firefox"  firefox  /usr/bin/firefox --private-window
winoptions Contains settings to control window appearance and behaviour which are specific to applications or groups of applications. Options can control the border, whether it appears on the task bar, the window list, the system tray and the work spaces. Also its layer, geometry, whether it can be moved, resized and closed.
startup Contains commands to be executed on icewm startup. This is an executable script with commands to tweak X11 settings and launch some applications which need to be active whenever icewm is started. It is run by icewm-session(1) when icewm starts.
shutdown Contains commands to be executed on icewm shutdown. This is an executable script with commands to be executed in the last stage of icewm termination. Typically they may undo some of the effects of the startup script. It is run by icewm-session(1) when icewm terminates.


icons Contains icons which are used to identify applications. Usually these files are in the XPM format, but the PNG and SVG image formats are also supported. The names of icon files may follow a specific naming pattern, like app_32x32.xpm. They start with a base name, usually this is just a single word. Then follows an underscore, followed by a size specification in the format SIZExSIZE. This is followed by a dot and the file extension, where the extension denotes the icon image format. Common sizes are 16, 32 and 48 for small, large and huge icons. This depends on the respective IconSize preferences options.

themes A directory to store themes. Each theme is stored in its own sub-directory in the themes directory. A theme contains at least a default.theme file, and optionally theme alternatives which are additional files which have a .theme file name extension and which contain tweaks of the default.theme file. How to create a theme is explained in the IceWM Theme Creation Howto.


IceWM supports window opacity and transparency in connection with an external compositor like compton(1). If a client window sets the _NET_WM_WINDOW_OPACITY property on its window then icewm will copy this to the outer frame window where compton will read it to adjust the opacity of the client window. The opacity can also be controlled by icewm when this is configured in the icewm-winoptions(5) file. Another way is to use icewmhint(1) to preset the opacity level immediately before starting the application. The opacity level of running applications can always be queried or modified by icesh(1).
The _NET_WM_WINDOW_TYPE properties which icewm sets on its windows are DIALOG, NOTIFICATION, POPUP_MENU and TOOLTIP. The output of icesh windows shows their WM_CLASS values. These can be helpful to configure compton.


Examples of the above configuration files can be found in the default installation path or in the system-wide defaults. See the output of icewm --directories for their locations.


ICCCM 2.0: partial. NetWM/EWMH: extensive. See the file COMPLIANCE in the distribution for full details.
