evilwm—minimalist window manager for X11
evilwm is a minimalist window manager for the X Window System. It features plenty of mouse and keyboard controls while providing a clean display, uncluttered by less useful window furniture (like title bars).
- specifies the X display to run on. Usually this can be inferred from the
- specifies an alternative program to run when spawning a new terminal (defaults to xterm, or x-terminal-emulator in Debian). Separate arguments with whitespace, and escape needed whitespace with a backslash. Remember that special characters will also need to be protected from the shell.
- specify a font to use when resizing or displaying window titles.
- frame colour of currently active, fixed active, and inactive windows
respectively. Either specify an X11 colour name like
goldenrod, or a hex triplet like
- width of window borders in pixels.
- enable snap-to-border support. distance is the proximity in pixels to snap to.
- ignore monitor geometry and use the whole screen dimensions. This is the old behaviour from before multi-monitor support was implemented, and may still be useful, e.g., when one large monitor is driven from multiple outputs.
- number of virtual desktops to provide. Defaults to 8. Any extras will only be accessible by pagers or using Control+Alt+(Left/Right).
- draw a window outline while moving or resizing.
- override the default keyboard modifiers used to grab keys for window manager
mask1is used for most keyboard controls (default: control+alt), and
mask2is used for mouse button controls and cycling windows (default: alt).
altmaskis used to modify the behaviour of certain controls (default: shift). Modifiers may be separated with + signs. Valid modifiers are shift, lock, control, alt, mod1, mod2, mod3, mod4, mod5.
- match an application by instance name and class (for help in finding these,
use the xprop tool to extract the WM_CLASS property).
-fixedoptions will apply to this match.
- apply a geometry (using a standard X geometry string) to applications
matching the last
- specify that application should be considered to be a dock, even if it lacks the appropriate property.
- specify a default virtual desktop for applications matching the last
-app. Note that virtual desktops are numbered from zero.
- specify that application is to start with a fixed client window.
- show help
- show program version
evilwm will also read options, one per line, from a file called .evilwmrc in the user's home directory. Options listed in a configuration file should omit the leading dash. Options specified on the command line override those found in the configuration file.
In evilwm, the focus follows the mouse pointer, and focus is not lost if you stray onto the root window. The current window border is shaded gold (unless it is fixed, in which case blue), with other windows left as a dark grey.
You can use the mouse to manipulate windows either by click/dragging the single-pixel border (easier when they align with a screen edge), or by holding down Alt and doing so anywhere in the window. The controls are:
- Button 1
- Move window.
- Button 2
- Resize window.
- Button 3
- Lower window.
Most keyboard controls are used by holding down Control and Alt, then pressing a key. Available functions are:
- Spawn new terminal.
- Delete current window. Hold Shift as well to force kill a client.
- Lower current window.
- H, J, K, L
- Move window left, down, up or right (16 pixels). Holding Shift resizes the window instead.
- Y, U, B, N
- Move window to the top-left, top-right, bottom-left or bottom-right of the current monitor.
- Show information about current window.
- Maximise current window vertically on current monitor (toggle). Holding Shift toggles horizontal maximization.
- Maximise current window to current monitor (toggle).
- Toggle visible state of docks (e.g., pagers and launch bars).
If compiled with virtual desktop support, these functions are also available:
- Fix or unfix current window. Fixed windows remain visible when you switch virtual desktop.
- Switch to specific virtual desktop (internally, desktops are numbered from zero, so this actually switches to desktops 0—7; this only becomes important if you use application matching).
- Switch to next lower numbered virtual desktop.
- Switch to next higher numbered virtual desktop.
- Switch to the previously selected virtual desktop.
In addition to the above, Alt+Tab can be used to cycle through windows.
