dwm - dynamic window manager
|
||||||
|
============================
|
||||||
|
dwm is an extremely fast, small, and dynamic window manager for X.
|
||||||
|
|
||||||
|
|
||||||
|
Requirements
|
||||||
|
------------
|
||||||
|
In order to build dwm you need the Xlib header files.
|
||||||
|
|
||||||
|
|
||||||
|
Installation
|
||||||
|
------------
|
||||||
|
Edit config.mk to match your local setup (dwm is installed into
|
||||||
|
the /usr/local namespace by default).
|
||||||
|
|
||||||
|
Afterwards enter the following command to build and install dwm (if
|
||||||
|
necessary as root):
|
||||||
|
|
||||||
|
make clean install
|
||||||
|
|
||||||
|
|
||||||
|
Running dwm
|
||||||
|
-----------
|
||||||
|
Add the following line to your .xinitrc to start dwm using startx:
|
||||||
|
|
||||||
|
exec dwm
|
||||||
|
|
||||||
|
In order to connect dwm to a specific display, make sure that
|
||||||
|
the DISPLAY environment variable is set correctly, e.g.:
|
||||||
|
|
||||||
|
DISPLAY=foo.bar:1 exec dwm
|
||||||
|
|
||||||
|
(This will start dwm on display :1 of the host foo.bar.)
|
||||||
|
|
||||||
|
In order to display status info in the bar, you can do something
|
||||||
|
like this in your .xinitrc:
|
||||||
|
|
||||||
|
while xsetroot -name "`date` `uptime | sed 's/.*,//'`"
|
||||||
|
do
|
||||||
|
sleep 1
|
||||||
|
done &
|
||||||
|
exec dwm
|
||||||
|
|
||||||
|
|
||||||
|
Configuration
|
||||||
|
-------------
|
||||||
|
The configuration of dwm is done by creating a custom config.h
|
||||||
|
and (re)compiling the source code.

|
||||||
|
.SH NAME
|
||||||
|
dwm \- dynamic window manager
|
||||||
|
.SH SYNOPSIS
|
||||||
|
.B dwm
|
||||||
|
.RB [ \-v ]
|
||||||
|
.SH DESCRIPTION
|
||||||
|
dwm is a dynamic window manager for X. It manages windows in tiled, monocle
|
||||||
|
and floating layouts. Either layout can be applied dynamically, optimising the
|
||||||
|
environment for the application in use and the task performed.
|
||||||
|
.P
|
||||||
|
In tiled layouts windows are managed in a master and stacking area. The master
|
||||||
|
area on the left contains one window by default, and the stacking area on the
|
||||||
|
right contains all other windows. The number of master area windows can be
|
||||||
|
adjusted from zero to an arbitrary number. In monocle layout all windows are
|
||||||
|
maximised to the screen size. In floating layout windows can be resized and
|
||||||
|
moved freely. Dialog windows are always managed floating, regardless of the
|
||||||
|
layout applied.
|
||||||
|
.P
|
||||||
|
Windows are grouped by tags. Each window can be tagged with one or multiple
|
||||||
|
tags. Selecting certain tags displays all windows with these tags.
|
||||||
|
.P
|
||||||
|
Each screen contains a small status bar which displays all available tags, the
|
||||||
|
layout, the title of the focused window, and the text read from the root window
|
||||||
|
name property, if the screen is focused. A floating window is indicated with an
|
||||||
|
empty square and a maximised floating window is indicated with a filled square
|
||||||
|
before the windows title. The selected tags are indicated with a different
|
||||||
|
color. The tags of the focused window are indicated with a filled square in the
|
||||||
|
top left corner. The tags which are applied to one or more windows are
|
||||||
|
indicated with an empty square in the top left corner.
|
||||||
|
.P
|
||||||
|
dwm draws a small border around windows to indicate the focus state.

.SH ISSUES
|
||||||
|
Java applications which use the XToolkit/XAWT backend may draw grey windows
|
||||||
|
only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early
|
||||||
|
JDK 1.6 versions, because it assumes a reparenting window manager. Possible workarounds
|
||||||
|
are using JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or setting the
|
||||||
|
environment variable
|
||||||
|
.BR AWT_TOOLKIT=MToolkit
|
||||||
|
(to use the older Motif backend instead) or running
|
||||||
|
.B xprop -root -f _NET_WM_NAME 32a -set _NET_WM_NAME LG3D
|
||||||
|
or
|
||||||
|
.B wmname LG3D
|
||||||
|
(to pretend that a non-reparenting window manager is running that the
|
||||||
|
XToolkit/XAWT backend can recognize) or when using OpenJDK setting the environment variable
|
||||||
|
.BR _JAVA_AWT_WM_NONREPARENTING=1 .
