This just-encountered network-transparency trouble occurred for the Windows version of octave, and the reason I am bringing it up here is to find out if this is a known issue or a new bug that I should report on your bug tracker.
I'm not sure, but have a look at:
http://bugs.winehq.org/show_bug.cgi?id=7416 http://bugs.winehq.org/show_bug.cgi?id=23952
Thanks, André, for those suggestions.
When I looked at 7416 it refers to support for multiple monitors which is quite different from the X network transparency which allows X terminals (a.k.a. boxes with a minimal Linux distribution that includes an X server but no desktop software like KDE) to use the local X server to display results and handle keyboard and mouse events so that X clients (e.g., KDE desktop, etc.) running on other machines accessible via a network look and feel like they are running on the local machine.
23952 looked more interesting since the quoted error message is very close to what I got. That one was due to a regression (apparently still not fixed) between 1.1.30 and 1.2.0 in how DRI was handled, and one workaround for the reporter was to disable DRI. In my case, "octave --version" worked when run directly on an box with integrated (g33) Intel graphics with DRI enabled, but my X-terminal where the failure occurred has DRI disabled because the graphics chip is SiS with no DRI support. So in essence I am getting reverse behavior to 23952; for a box with DRI turned on, octave --version succeeds, but for a box with DRI turned off it fails. Once I can get access to the Intel box again, I will try taking the network transparency out of the mix by turning off DRI on the intel (direct) box to see if that generates the issue. If octave --version works on that box regardless of whether DRI is on or off, then that would be an even stronger case that it is the (lack of) network transparency for this particular (and rather uncommon) case that is the culprit.
