I bumped into this bug - actually https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/105938 (marked as a dup of this).
I found a workaround - which I document here for others. The problem is not xdmcp - the problem is a failing dns lookup of the hostname of the machine. I configured dnsmasq on the gdm machine, named myhost.org In /etc/dnsmasq.conf I added this :- local=/myhost.org/ That forces any lookups in that domain to come from /etc/hosts xdmcp magically started working again. Just this change. -- XDMCP lstening on udp6 instead of udp https://bugs.launchpad.net/bugs/58071 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase-workspace in ubuntu. -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
