solved.
sorry to have bothered you, but somehow setting the gconf key
/apps/gdm/simple-greeter/disable_restart_buttons does work.
as i looked over it once more with a colleague setting it as mandatory
did work. i don't know what is different, because i was sure i did do
that before. but well, so far it worked on several systems.
so sorry to bother you all with that.
in any case someone else stumbles upon this problem, my actual solution
now is rather simple:
gconftool-2 --direct --config-source xml:readwrite:/etc/gconf \
/gconf.xml.mandatory -t bool -s /apps/gdm/simple-greeter \
/disable_restart_buttons true
cheers,
jackie
