xserverCrash

Im having trouble with getting my M15x's xserver to stop crashing and throwing me out to the login screen. a lot of process appear to be unharmed most things are there when i log back in its almost instant.  No other errors or popups. Machine all and all is great and don't have to reboot the machine or anything.
