Introduction
Compiz is a window manager for the X Window System on Linux. It uses 3D graphics hardware to display windows and special effects.
Unfortunately, using Compiz together with Java's Swing GUI library causes problems (see bug report): DrJava or your entire system may crash.
This issue is caused by an incompatibility between Compiz and Java, and we, the developers of DrJava, cannot do anything to fix this problem. We hope that future versions of Java and Compiz will address the incompatibility. In the meantime, we recommend that you disable Compiz if you experience problems. We also suggest that you use the latest versions of Compiz and Java, so you can benefit from possible bug fixes made by Sun and the Compiz developers.
Below, we have instructions for some common Linux distributions.
