Only getting blank screen

I just downloaded the pre release (0.21) nmeditor and I am only getting a blank screen when I use the java command to start it up. I am using JRE 1.5_09 on Linux Fedora Core 6 with the latest nvidia driver and I am also using AIGLX/Compiz on the machine. Anyway here is a copy of my log file.

Nomad Version 0.2.1 (pre-release)

[os]
Linux \ 2.6.18-1.2798.fc6 \ i386

[java vm]
Java HotSpot(TM) Client VM \ Sun Microsystems Inc. \ 1.5.0_09-b03

[java path]
java.library.path=/usr/java/jre1.5.0_09/lib/i386/client:/usr/java/jre1.5.0_09/lib/i386:/usr/java/jre1.5.0_09/../lib/i386
java.class.path=nomad.jar

I am suspicious that I have to tell the Java Runtime to use the Open GL driver when running this program but it seems to work OK on web graphics so I'm not too sure about it. Anyway I read on this forum that you can do this by using this command

java -Dsun.java2d.opengl=true
or System.setProperty("sun.java2d.opengl", "true");

But neither of them seem to work and I get output errors on them both.
java -Dsun.java2d.opengl=true gives me
sage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args...]
(to execute a jar file)
etc, and or System.setProperty("sun.java2d.opengl", "true");
gives me: -bash: syntax error near unexpected token `"sun.java2d.opengl",'. Anyway ive seen all the posts saying that it works so im gonna go and test it on my Ububtu box.

If anyone helps I will appreciate it very much.

Hi,

to use the opengl pipeline you have to start nomad with the command

Thanks but im still coming up with a blank screen when I open it. My modular is conected and turned on so there is still some outstanding issue here. Here is the terminal output.

Hi,

i've done some research on the problem. It's a bug in the java jre. For reference see
http://lists.freedesktop.org/archives/compiz/2006-June/000224.html
http://bugs.sun.com/bugdatabase/view_bug.do;jsessionid=10a69c490eaa4dd4f7ac02e508:WuuT?bug_id=6429775

On the bug report someone mentions that the problem is gone in the latest java version jdk 1.5 update 10 (jdk-1.5.0_10) perhaps updating will fix your problem too.

Please let me know if this helped you.

Hi,

you did everything right. There is no difference between jdk to jre from the user perspective. I think you have to wait and try out upcoming java releases until the bug is gone. Java 1.6 should be released in the next 1-2 months if I am right.

Well, there is one last thing you can try out. It sometimes happens if you install a new java jre that the old one is still installed. You can check if the command java -version prints the version number 1.5.0_10. If not then you are still using the old jre. Then you should update the JAVA_HOME variable or use the absolute path of the java command. For example: /opt/sun-jre-1.5.0.10/bin/java -jar nomad.jar
(The path is probably different).

Sorry that I have no better solution.

Ok Thanks for that Christian I guess I will wait until the next JRE release. I even tried to run the Windows Nord Modular editor under WINE but for some reason WINE wont stat my MIDI in ports either. I have a Waldorf Pulse as well and its editor when run in WINE says that the device ID is out of the range of the computer (funny that seeings the device ID is set to 3 on the synth itself).

As far as the issue of which JAVA is the default on my system I cant remeber the process of the top of my head but I know that the current default is set to JRE 1.5.0_10 because I set it up that way. here is the which java output.
