gridwm
|
||||
------
|
||||
|
||||
gridwm is an automatic X11 window manager which arranges all windows in a grid.
|
||||
|
||||
|
||||
Requirements
|
||||
------------
|
||||
In order to build gridwm you need the Xlib header files.
|
||||
|
||||
|
||||
Installation
|
||||
------------
|
||||
Edit config.mk to match your local setup. gridwm is installed into
|
||||
the /usr/local namespace by default.
|
||||
|
||||
Afterwards enter the following command to build and install gridwm (if
|
||||
necessary as root):
|
||||
|
||||
make clean install
|
||||
|
||||
|
||||
Running gridwm
|
||||
--------------
|
||||
Add the following line to your .xinitrc to start gridwm using startx:
|
||||
|
||||
exec gridwm
|
||||
|
||||
In order to connect gridwm to a specific display, make sure that
|
||||
the DISPLAY environment variable is set correctly, e.g.:
|
||||
|
||||
DISPLAY=foo.bar:1 exec wmii
|
||||
|
||||
This will start gridwm on display :1 of the host foo.bar.
|
||||
|
||||
|
||||
Configuration
|
||||
-------------
|
||||
The configuration of gridwm is done by customizing the config.h
|
||||
source file.
