I have the same issue on a Dell precision M4300. It also happens when not using hotkeys, almost randomly, a few times a hour. Under both 32 and 64 bits.
As a side note, when the problem happens, i press ctrl-alt-F1 and the screen flickers to text mode, but very often comes back "by itself" to graphic mode.
