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. |
