Comment 78 for bug 86103

Applied both set of workarounds:
sudo sed -i 's/XINERAMA/FAKEEXTN/g' /usr/lib/jvm/java-6-sun-1.6.0.04/jre/lib/i386/libawt.so
sudo sed -i 's/XINERAMA/FAKEEXTN/g' /usr/lib/jvm/java-1.5.0-sun-1.5.0.14/jre/lib/i386/libawt.so
and
export LIBXCB_ALLOW_SLOPPY_LOCK=true

and still get:

ken@neptune:~/BGBlitz$ ./bgblitz.sh
JAVA = java
JVM_OPTS = -Xmx128m -server
HOME = /home/ken/BGBlitz
