ssh changed some of it's options "recently" so that -X no longer
forwards X the way it used to. ssh -X forwards in some sort of 'safe'
mode which doesn't allow apps to do certain things they might want to
do. Try ssh -Y which "[e]nables trusted X11 forwarding" according to the
manpage.


The man page of ssh says to be cautious of the -X option, and does not 
mention any caution next to the -Y option.  Perhaps that could use some 
clarification upstream, and we should mention this change of behavior in 
FC's release notes?
