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:
sudo apt-get update
sudo apt-get install sun-java6-jre
sudo update-java-alternatives -l
sudo update-java-alternatives -s sun-java6-jre
"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/"
