I’m running Ubuntu with an XGL session and Compiz, and tried installing ArgoUML a java based cross platform UML designer. However when the application was run, the main window did not render correctly, it was blank with no menus or content.
A friend informed me of the solution, which affects Netbeans IDE as well, so the following:
sudo gedit /etc/environment
Add the following line
save and close.
You may need to restart the session or reboot to pick up the environment setting change.
