I’m unable to either auto-login or change my login theme. Here’s my /etc/sysconfig/displaymanager
## Path: Desktop/Display manager
## Description: settings to generate a proper displaymanager config
## Type: string(kdm,kdm3,kdm4,xdm,gdm,wdm,entrance,console)
## Default: ""
#
# Here you can set the default Display manager (kdm/xdm/gdm/wdm/entrance/console).
# all changes in this file require a restart of the displaymanager
#
DISPLAYMANAGER="kdm"
## Type: yesno
## Default: no
#
# Allow remote access (XDMCP) to your display manager (xdm/kdm/gdm). Please note
# that a modified kdm or xdm configuration, e.g. by KDE control center
# will not be changed. For gdm, values will be updated after change.
# XDMCP service should run only on trusted networks and you have to disable
# firewall for interfaces, where you want to provide this service.
#
DISPLAYMANAGER_REMOTE_ACCESS="no"
## Type: yesno
## Default: no
#
# Allow remote access of the user root to your display manager. Note
# that root can never login if DISPLAYMANAGER_SHUTDOWN is "auto" and
# System/Security/Permissions/PERMISSION_SECURITY is "paranoid"
#
DISPLAYMANAGER_ROOT_LOGIN_REMOTE="no"
## Type: yesno
## Default: yes
#
# Let the displaymanager start a local Xserver.
# Set to "no" for remote-access only.
# Set to "no" on architectures without any Xserver (e.g. s390/s390x).
#
DISPLAYMANAGER_STARTS_XSERVER="yes"
## Type: yesno
## Default: no
#
# TCP port 6000 of Xserver. When set to "no" (default) Xserver is
# started with "-nolisten tcp". Only set this to "yes" if you really
# need to. Remote X service should run only on trusted networks and
# you have to disable firewall for interfaces, where you want to
# provide this service. Use ssh X11 port forwarding whenever possible.
#
DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN="no"
## Type: string
## Default:
#
# Define the user whom should get logged in without request. If string
# is empty, display standard login dialog.
#
DISPLAYMANAGER_AUTOLOGIN="timothy"
## Type: yesno
## Default: no
#
# Allow all users to login without password, but ask for the user, if
# DISPLAYMANAGER_AUTOLOGIN is empty.
#
DISPLAYMANAGER_PASSWORD_LESS_LOGIN="yes"
## Type: yesno
## Default: no
#
# Display a combobox for Active Directory domains.
#
DISPLAYMANAGER_AD_INTEGRATION="no"
## Type: list(root,all,none,auto)
## Default: auto
#
# Determine who will be able to shutdown or reboot the system in kdm. Valid
# values are: "root" (only root can shutdown), "all" (everybody can shutdown),
# "none" (nobody can shutdown from displaymanager), "auto" (follow
# System/Security/Permissions/PERMISSION_SECURITY to decide: "easy local" is
# equal to "all", everything else is equal to "root"). gdm respects the
# PolicyKit settings for ConsoleKit. Shutdown configuration can be done via
# the polkit-default-privs mechanism.
#
DISPLAYMANAGER_SHUTDOWN="auto"
## Type: string(Xorg)
## Path: Desktop/Display manager
## Default: "Xorg"
#
DISPLAYMANAGER_XSERVER="Xorg"
## Path: Desktop/Display manager
## Description: settings to generate a proper displaymanager config
## Type: string
## Default:
## Config: kdm3
#
# space separated list of users for which icons should be shown in KDM
# if empty, then take system defaults
#
KDM_USERS=""
## Type: string
## Default:
#
# Special greeting words in kdm
#
KDM_GREETSTRING=""
## Type: string
## Default:
#
# Defines extra Server Arguments given to the kdm display manager when
# starting a local display. Useful to override e.g. the -dpi setting.
#
DISPLAYMANAGER_KDM_LOCALARGS=""
## Type: string
## Default: SUSE
#
# Define the theme to be used by kdm. If empty, the traditional login
# window is used (which lacks some features)
#
DISPLAYMANAGER_KDM_THEME="HeliumOne"
## Type: yesno
## Default: yes
#
# Allow local access of the user root to your display manager. Note
# that root can never login if DISPLAYMANAGER_SHUTDOWN is "auto" and
# System/Security/Permissions/PERMISSION_SECURITY is "paranoid".
# This settings currently works only with KDM.
#
DISPLAYMANAGER_ROOT_LOGIN_LOCAL="yes"
By the way, do you notice the line where it says “## Config: kdm3”? I don’t have kdm3…
I’m using 12.1 and KDE 4.9.3.
