Keyboard layout different at lockscreen

[Pengatom]

Hi,

On one of my machines I have an issue with login back in after a logout (either manual or by screensaver).
When I try to type my password, some of the keys doesn't work.
I have a Norwegian keyboard layout, and it still shows that it is selected at the top right of the screen.
To be able to log in, I have to select another user from the drop-down menu, then when the screen changes to display all available users, the keyboard works again and I can log in as the "original" user.
I'm using Synergy (same keyboard over several machines) but the issue is both on the laptop keyboard, usb keyboard(s) and the keyboard that I use with Synergy, so I doubt it is an hardware issue.

I'm using Ubuntu 14.04.

Any help would be highly appreciated!

Regards
Pengatom

Some more troubleshooting today.
I've changed the password to one that uses the same keys in norwegian and whatever layout I have, and when logging in via ssh, I notice the same behavior as I've seen when the screen is locked.
Does this make any sense to anyone?
