When you disable ipv6 from the yast2 network, system correctly remove the assignation of ipv6 addresses from everywhere but there is an annoying bug in openssh that break the possibility to make X11 tunnels because it seems that ssh try to bind X11 tunnel to an ipv6 address even with ipv6 disabled causing this kind of message in /var/log/messages:

Aug 17 16:47:28 franz2011 sshd[6300]: error: Failed to allocate internet-domain X11 display socket.

this can avoided configuring correctly the file /etc/ssh/sshd_config with the parameter:

AddressFamily inet

and restarting sshd.
