Incanter produces a blank window over ssh -X or -Y about incanter

[ktsujister]

I'm using ssh -Y from my Mac OS X Lion to ubuntu 12 machine which has incanter (1.3.0) code, and graphs are displayed properly.
What's your environment, and is environmental variable $DISPLAY set?

I tested with a relatively current Debian unstable machine connecting to
itself via "ssh -Y foo@localhost"; other X apps like xeyes work fine
over that link.

Also, I'm using this project.clj:

(defproject incanter-helloworld "0.1.0"
:description "The Incanter version of hello world."
:dependencies [[incanter "1.3.0"]])

this core.clj:

(ns incanter-test.core
(:use (incanter core stats charts)))

(defn main [& args](let [lengths %28read%29]
%28view %28histogram lengths :nbins 100%29%29))

(main command-line-args)

and this invocation:

java -cp 'lib/*' clojure.main src/incanter_test/core.clj < lengths

That works fine when logged in directly, but not over ssh.

Oh, and here's the java version:

$ java -version
java version "1.7.0_03"
OpenJDK Runtime Environment (IcedTea7 2.1.3) (7u3-2.1.3-1)
OpenJDK 64-Bit Server VM (build 22.0-b10, mixed mode)

Thanks for the help.

I tested like below.

and I tested with
% lein trampoline run < lengths

and your sample still worked.

So I'm not sure if this is incanter's issue.

I tried something similar to your example, and still saw the blank
screen.

Though I'm also running xmonad; perhaps its insistence on resizing the
window is causing trouble -- I'll see about testing without it.

I suppose it could also have something to do with Debian (or just Linux)
as the ssh (X) client. I don't know if it's convenient, but if you
happen to have vnc access (or similar) to your Ubuntu machine, you might
be able to test that too.

Thanks

@rlbdv I was just wondering if you ever fixed this. I'm using xmonad too and having the same issue as you. I'm not ssh-ing though.

I haven't tried in a while, but no I never got it to work.

I believe it worked when I ran incanter locally, but I'm not sure I was
using xmonad with that account -- so I suppose it could be related to
xmonad rather than to ssh X forwarding.

I'll try to test locally with xmonad when I get a chance.

I finally got around to testing this more directly, and it looks like it probably does have something to do with xmonad. For example, on a (recent) Debian system, with xmonad installed, a "(view (histogram (sample-normal 1000)))" produces a blank window if I log in via gdm3 to an xmonad or xmonad+gnome session. It behaves normally with a plain gnome session.

Please let me know if I can provide any further information, and I'll probably contact the xmonad developers as well.

Thanks.

[rlbdv]

The xmonad community had the answer -- it appears to be a known java (AWT) problem, and one solution is to export _JAVA_AWT_WM_NONREPARENTING=1 before running incanter.

http://code.google.com/p/xmonad/issues/detail?id=544

So I suspect it's safe to close this bug.

[alexott]

Thank you, I'lm closing the bug

[denlab]

Just for info: A friend of mine ( @ardumont ) has the same kind of problem with the StumpWM window manager.

[ardumont]

Yes, I concur with @denlab, I have the problem on stumpwm.
And yes, this export variable solve this. So, not a incanter problem.

Thanks, I will no longer need to switch!!!
