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.4.wdm file executable using the command:
'chmod -x /etc/rc.d/rc.4.wdm' or using your favorite file manager.
Then you need to replace your standard /etc/rc.d/rc.4 file with
the one provided by this package. The best way is to back up your
original rc.4 file by changing the name of it to something like
'rc.4.orig'. then either change the name of the rc.4.wdm file
to just rc.4 or create a link to it with these commands:
cd /etc/rc.d
ln -sf rc.4.wdm rc.4

Then, when you reboot you should be greeted with the GUI login
interface (if you have rebooted into runlevel 4).
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.

If you are not already booting into runlevel 4, you can set that
up by editing your /etc/inittab file and changing the line:
id:3:initdefault:
to this:
id:4:initdefault:
A better and safer way to use runlevel 4 is to pass 'init 4' as
a boot-time kernel option. If you are using the lilo bootloader
then you can create a new entry in the /etc/lilo.conf file by
copying the entry your are currently using and adding this:
append = "init 4"
to the entry for GUI login. You'll probably want to change the
'label' line also to something which indicates that the entry
is used for booting with a GUI login. After editing the file,
you must run the command 'lilo' in order to apply the changes.

Configuring for use with the grub bootloader is even easier.
Just create a new entry in your menu.lst file by copying the
entry you are currently using. Change the title by adding something
like 'GUI login'. Then just add 'init 4' to the line with the
kernel options. Below is an example.
Original entry:
kernel (hd0,0)/vmlinuz-2.4.36 root=/dev/hdb3 ro vga=791
Modified entry:
kernel (hd0,0)/vmlinuz-2.4.36 root=/dev/hdb3 ro vga=791 init 4
Then, when you reboot you'll see the new menu entry.

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,
