Errors with Lightzone java and Xinerama.

If you are getting errors along the lines of:

xcb_xlib unlock: Assertion 'c->xlib.lock' failed

Then you have probably found the bug in Java about Xinerama and need to do a little fix in the jre to make sure that it does not happen. Run the following command in your lightzone installation:

sed -i 's/XINERAMA/FAKEEXTN/g' jre/lib/i386/xawt/libmawt.so

This should disable the check for Xinerama and all should work fine.
