so it's not clear to me if it's looping serverside or clientside.

i'm not quite prepared to dive in with gdb myself, if there's something not quite that deep i can help with say so, meanwhile i'm still using plain vanilla vnc via portforwards, a bit slow and clunky but it just works. i look forward to the speed advantage and rootless handiness of nx/x2go, the portforwards are easy to me thus i'm not at all interested in nx session handling, too bad that's the part that's broken and keeping me from using it, i wish there were a way to just manually connect like vnc..
