Remote ssh -Y display: cannot create graphics configuration

[Kevin Manross]

Hi Michael,

BTW - ssh -Y and -X are nearly the same thing, though I think the -X is 
a bit more robust.

from the man page:

-X Enables X11 forwarding. This can also be specified on a per-
host basis in a configuration file.

X11 forwarding should be enabled with caution. Users with the
ability to bypass file permissions on the remote host (for the
user’s X authorization database) can access the local X11 dis-
play through the forwarded connection. An attacker may then be
able to perform activities such as keystroke monitoring.

-x Disables X11 forwarding.

-Y Enables trusted X11 forwarding.


The error you are getting seems to indicate that your versions of Java3D 
aren't playing nicely with each other (between your local machine and 
your remote SPARC machine which is running the IDV, if I understand you 
correctly).

I wish I could be more helpful, but I'm still trying to figure out which 
graphics controllers are being used when using the ssh -Y or -X options 
and which Java(2/3)D (local/remote) takes care of mouse inputs.

-kevin.
