Dumb question - have you compared /etc/ssh/ssh.conf on your laptop
to the same file on machines that do not give you trouble? It sounds
like an xauth problem on the laptop...

# If this option is set to yes then remote X11 clients will have
full access
# to the original X11 display. As virtually no X11 client supports
the untrusted
# mode correctly we set this to yes.
        ForwardX11Trusted yes
