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.
