Welcome to the Slackware Documentation Project

SLiM (Simple Login Manager)

SLiM es un acrónimo de Simple Login Manager . Si usa uno de los entornos de escritorio livianos como Xfce, Fluxbox, Blackbox o WindowMaker, es posible que desee usar SLiM.

Slackware viene por defecto con dos administradores de inicio de sesión que, en teoría, podrían hacer el trabajo, pero cada uno tiene sus deficiencias:

  • KDM (pesado)
  • XDM (Visualmente poco atractivo)


SLiM no viene en el disco de instalación estándar de Slackware, pero puede instalarlo fácilmente desde SBo.

Basic configuration (system level)

All login managers (SLiM, GDM, KDM, XDM) are supposed to start in runlevel 4, so make sure this is actually your default runlevel. Take a peek in /etc/inittab and see if you have the following:

# Default runlevel. (Do not set to 0 or 6)

You can also check the current runlevel of your machine by typing the following command:

# who -r
         run-level 4  2012-07-04 21:44                   last=S

In the example shown above, the current runlevel of your machine is also “4”.

Now edit /etc/rc.d/rc.4 and add a few lines to start SLiM automatically on boot. The order is important here. Insert the stanza right before the one that manages GDM, like this:

# Tell the viewers what's going to happen...
echo "Starting up X11 session manager..."

# Start SLiM...
if [ -x /usr/bin/slim ]; then
  exec /usr/bin/slim

# Try to use GNOME's gdm session manager.  This comes first because if
# gdm is on the machine then the user probably installed it and wants
# to use it by default:
if [ -x /usr/bin/gdm ]; then
  exec /usr/bin/gdm -nodaemon

Basic configuration (user level)

There's one last thing left to do before your shiny new login manager can be put to use. Run the following command as a normal user:

$ xwmconfig

This will launch Slackware's window manager selection dialog box. Choose your window manager (Xfce, Fluxbox, Blackbox, whatever) and hit OK. This spews out a new ~/.xinitrc file in your home directory. We won't go into the gory details of this file, since the one interesting thing about it is that it enables you to log in using SLiM.


SLiM's main configuration file is /etc/slim.conf. It's very clear and well commented and pretty much self-explanatory. For example, you might want to decide that you prefer activating numlock on boot. In that case, just uncomment the relevant line in slim.conf like this:

# Activate numlock when slim starts. Valid values: on|off
numlock             on


SLiM's default theme may or may not appeal to you. If the latter is the case, then you can either install another theme, or create your own theme from scratch.

SBo's slim build comes with an alternate theme called slackware-black, created by Frank Caraballo. You can activate this theme by editing the according line in /etc/slim.conf and replacing default with slackware-black, like this:

# current theme, use comma separated list to specify a set to 
# randomly choose from
current_theme       slackware-black

An alternative Slackware theme is available on ngc891's blog.

The SLiM website has a page with a collection of themes. Installing one or more of these themes is quite simple. Take a look in /usr/share/slim/themes. You'll see two directories: default and slackware-black. To install a theme, simply download the theme tarball and uncompress it in the /usr/share/slim/themes directory (as root, of course). To activate the theme, edit the current_theme line in /etc/slim.conf accordingly.

The site also sports a nice tutorial about your own theme creation.

Install a collection of ready-made themes, and then take a peek in the respective theme directories to see how it's actually done.
