how to cancel keyboard P key, shortcuts to changing resolution on gnome through NX (nomachine)

Question

I don't know why, but suddenly, after connecting to a gnome-session through NX, every time when I press (lower case) p, the session changes resolution (instead of just printing 'p' on the screen).

Any idea how to revert it?

Notes:

1. Reconnecting to the session didn't help.
2. I am not a superuser on the NX server
3. I am a superuser on the NX client
4. Yesterday I've used xrandr on the remote to change the resolution. However, everything was fine until an hour ago.

EDIT: I have connected to the session from a client on a different computer, and the issue persists. So I suspect it is related to the gnome session

Thank you!

Answer 1

Solution was simple: Log out from the gnome session and log-in (a new session).
