The MSI K9AGM2-FIH uses an AMD ATI chipset so you are at the mercy of the ATI Linux drivers. LMCE uses all of the most advanced (and difficult/buggy/ hard to implement) features of the graphics interface. And only Nvidia has support for them today, just barely above experimental status. There has been lots of discussion about ATI, and Intel drivers but support for compositing and opengl isn't what it is for nvidia yet. As soon as it is available on something else and it works better we will all move.
