Great. Am I correct that you're running KDE4 and use 'kdm' as your login manager? Because I made a test with 'gdm' (it's Gnome default login manager) and it works. I'd like to suggest to try 'Entrance' - it's another login manager you already have installed with 'E-metapackage'. You can make it with YAST, but it'd me much more simple just open your terminal, became 'root' (enter 'su' and root password) and type several commands.

1) to begin with just check what you already have as enabled services (here's the example from my box, you may receive a bit different output, but it's ok):

chkconfig -l | grep dm

earlyxdm 0:off 1:off 2:off 3:off 4:off 5:off 6:off
gdm 0:off 1:off 2:off 3:off 4:off 5:off 6:off
mdadmd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
xdm 0:off 1:off 2:off 3:off 4:off 5:off 6:off

'mdadmd' is not ineresting for us. See, that I turn all login managers 'off' (gdm, xdm and earlyxdm). May be you'll see a line with 'kdm' also. We need to turn it also off.

2) Disable all of this managers:

chkconfig earlyxdm off
chkconfig gdm off
chkconfig xdm off

may be you'll also need to type

chkconfig kdm off

3) And finally you'll need to enable 'Entrance':

chkconfig entrance on
chkconfig entrance 35

4) Just check the results:

chkconfig -l | grep entrance

entrance 0:off 1:off 2:off 3:on 4:off 5:on 6:off

That's it. You need to reboot to activate the changes. If something goes wrong - don't panic. Press Alt+Ctl+F1 (you'll get the console login prompt, or Ctl+Alt+F2), login as 'root' and type (revert all back to defaults):

chkconfig earlyxdm on
chkconfig gdm on
chkconfig xdm on
chkconfig entrance off
reboot

(or may be you'll type 'chkconfig kdm on'). The idea is just to restore the case you had before.

Good luck! And thanks for your patience and comments!
