If by "jamming" you mean that you can't type in your password, this
happens to me coming out of sleep almost every time but on 14.10 not
14.04. I don't remember it happening to me on 14.04.

I haven't file a bug report because it doesn't happen all the time and
apport may have filed one for this problem on my behalf for
indicator-keyboard-service.

My workaround is to click on the top right computer icon and then
click in the password field - and I can then log in.
