This is an old bug, but just in case somebody is still experiencing it in a newer release, I can confirm than this problem is due to the mouse appearing in the exact center of both displays (nvidia gtx 550 ti in my case, two monitors 1024x768 with twin view) and gdm thinks than it's on the one of the right, since must be one pixel to the right or left since technicaly there's no real "center" betwen both screens.
The solution from post Joerg in post #11 worked for me, thanks a lot! It forces gdm to set the mouse closer to the 0x0 coordinates, making it appear in the first monitor by default and so the gdm, login screen, language selector, etc...
