====== Blank screen with maple 12 on Ubuntu lucid if running compiz ======

Maple 12 will display a blank screen if compiz (Desktop effects) are active. This is because the default java install (openjdk) causes trouble with the combination compiz+maple.

Quick fix: Disable compiz
Real fix, without losing compiz:
  * Uncomment partner repositories in /etc/apt/sources.lst
  * ''sudo apt-get update''
  * ''sudo apt-get install sun-java6-jre''
  * ''sudo update-java-alternatives -l''
  * ''sudo update-java-alternatives -s sun-java6-jre''
  * Edit the maple start file (/opt/maple12/bin/maple on my system). Locate your system type (bin.X86_64 in my case) and change the java jre variable:

<code>
"bin.X86_64_LINUX")
# -brb-
  MAPLE_JRE_BIN="/usr/lib/jvm/java-6-sun/jre/bin/"
# MAPLE_JRE_BIN="$MAPLE/jre.X86_64_LINUX/bin/"
</code>
