then you have to :
mount -o remount, rw /
nano /usr/lib/python2.7/site-packages/configgen/generators/moonlight/moonlightGenerator.py
- add
commandArray.append('-surround')
just beforecommandArray.append('-app')
(you MUST respect the indentation !!!!!) - save the file (CTRL+X, say yes everytime)
- launch your game
