I've just discovered that I'm still having this problem - the session is lost after I resume from suspend... It seems to work if laptop is suspended only for a short period of time, like in the above posts, when I was suspending it for few seconds for testing purposes. But when I suspended it and left it for roughly 10 minutes I was back to GDM after I resumed. At the moment I have my bluetooth disabled in BIOS and I also removed all the bluetooth related packages from my ubuntu... So it looks like there's more to this issue than just bluetooth
