Comment 29 for bug 728101

Killing gnome-power-manager completely has mostly fixed it for me on my HP 6710b, but it's still done the same thing upon two occasions in the past ten days (once about six days ago, once earlier today). I've probably closed the lid for the required length of time 10-15 times in that period. So I don't think that gnome-power-manager is the issue, but is rather just pretty good at triggering it.

And the "sudo gdm restart" technique takes it to the logon screen and says that I'm logged in, but the session dies as soon as it tries to log in to it. (It does the same thing after hibernate the two times I've tried it, too. But I should test it more thoroughly and create another bug report about that; wonder how long it'll take before I get round to it.) Normal "switch user" works, however.
