Ubuntu - Fix limited mouse movement in fullscreen minecraft

If you press f11 to go into fullscreen gaming mode in ubuntu, you may notice that you cant perform a 360 degree spin, and that your mouse movement is limited. The solution to this problem is to go into your compiz configuration settings and un-tick any options within the 'window' section (towards the bottom). After doing this the mouse movement restriction is gone. You will just have to remember to enable it after you finish playing. Alternatively, you can log out and log in again with 'classic no effects' mode and launch the game, which will also remove any problems.
