= For SUSE =

For KDM
Look at /etc/xinet.d/vnc, outcomment the line saying  from the first vnc section. It should look like this: service vnc1 {        #disable        = yes socket_type    = stream protocol       = tcp wait           = no         user            = nobody server         = /usr/bin/Xvnc server_args    = -SecurityTypes None -inetd -once -query localhost -geometry 1024x768 -depth 16 type           = UNLISTED port           = 5901 }
 * enable xinetd's vnc service

Edit /opt/kde3/share/config/kdmrc. In the [xdmcp] section, make sure  is set to true: enable=true rcxinetd restart rcxdm restart
 * allow your display manager to serve xdmcp:
 * set yast2 -> System -> /etc/sysconfig editor -> Desktop -> Display Manager -> DISPLAYMANAGER_REMOTE_ACCESS to true
 * restart the services (killing your login)
 * connect with vncviewer localhost:1
