Hi

I know this problem too. My solution is to start the session without the
X-Server. If I did only a ssh -C then it works while ssh -XC doesn't.

If you have only a terminal connection then nothing which requires X is
started. I think the problem belongs more to the OS or user environment
as to idl.

regards
Reimar
