Every time after resume, have to unlock/logon twice

[Thomas Novin]

My computer suspends after leaving it for 1 hour. When using it again, it resumes and I have to login to unlock. Then right after login, the screen goes black and I'm at the logon prompt again.

Settings are both suspend & turn screen off after 1 hour.

Note! I cannot reproduce this problem when I lower the timers to screen off after 10 minutes and suspend 30 minutes.

This is also affecting me on a fresh install of Ubuntu 14.04, on two separate machines - my HP Compaq 8710W (64-bit + NVIDIA) and my IBM ThinkPad T43 (32-bit).
