Problems forwarding X with ssh

Hi guys.

I want to ask you about a "problem" I'm having. I have found a workaround for it but I'm not able to realize what's producing this strange effect.

I'm using a laptop with a vanilla Slackware 12.0 to connect to a Solaris Ex. Dev. Ed. 9/07 via ssh (openssh-4.6p1). Both of these work perfectly:

Code:

$ ssh -Y host

Code:

$ ssh host

and then

Code:

export DISPLAY=mylaptop:myscreen

But If I connect with

Code:

$ ssh -X host

I can indeed connect, I can launch a program but the windows are displayed very bad: widget positions is offset vertically and horizontally, windows are partially rendered. The point is that a complex application is unusable.

Is anyone able to explain me what's the problem with ssh -X compared to ssh -Y?

Thanks,
Enrico.

Just an idea: Try enabling your logging and see if that reveals anything 'ssh -vvv'

Thanks mjmwired.

Trying ssh verbose mode, I realized that the only affected programs are Java programs! It seems as something prevents Java programs to display properly.

Just an idea: can "Java bridge for GNOME" be the guilty? I'm running KDE in my slackware box.

Bye,
Enrico.

I've never had any problems connecting from KDE on SuSE to Solaris and running graphical apps that use the Java bridge.

Thanks for confirming that, Brian.

It would have made little sense to me, though: why should it work with ssh -Y and not with ssh -X. I don't know, I would like to try with another version of Solaris (maybe 10rev4) but I can't do that now.

Bye,
Enrico.
