I need one ssh-agent per X session that all child processes can access.

Probably you are right. But how to disable it in QT4 x2goclient? If I add

Host *
ForwardAgent no

to ~/.ssh/config it affects a separate ssh session but not
x2goclient's one. And I failed to find any command line/GUI x2goclient
option that is related to ssh agent forwarding.
