Hi Satish and Artem,

-Y is equivalent to the "ForwardX11Trusted yes" in your ~/.ssh/config
option and -X is equivalent to the "ForwardX11 yes" (see 'man
ssh_config' for details on both of these)

-Y does not enable -X automatically, so either you set both options as
defaults in your ~/.ssh/config or use them on the command-line:
    ssh -X -Y remotemachine

Cheers,
Sebastien
