You'll need WindowMaker-0.92.0 to use this version of WDM.
If using earlier version of WindowMaker, use WDM 1.27 or 1.26

This version of WDM is set up for use with Slackware or other
compatible systems and includes a configuration tool, ConfigureWDM.

In order to use the WDM Login and Display Manager, you'll need
to make the /etc/rc.d/rc.wdm file executable using the command:
chmod -x /etc/rc.d/rc.wdm
or using your favorite file manager.

Then, when you reboot you should be greeted with the GUI login
interface.
You can also test WDM without rebooting by running wdm directly,
or executing /etc/rc.d/rc.wdm. Be sure you have shut down any
running display managers and/or X sessions first.

When you install the package, the configuration utility is run
automatically, detecting which window managers are installed on
your system and setting up the default behaviour.

If you want to change the way WDM functions, you can manually
edit the main config file in /etc/X11wdm/wdm-config, or even
better, use the provided utility in /etc/X11wdm/ConfigureWDM.

ConfigureWDM makes configuration a little easier and provides
a few options for making wdm more Slackware-compatible. It uses
its' own configuration file in /etc/wdm.conf, with a familiar
format. Read /etc/wdm.conf for more details about the options.

When wdm runs it reads its' main configuration file located
in /etc/X11/wdm/wdm-config. For further fine tuning you can
edit that file directly, or edit the *.in files which are used
by ConfigureWDM and re-run ConfigureWDM.

Development of this adaptation of WDM for Slackware is proceeding,
so please check for updates and send comments or suggestions
