Comment 9 for bug 173517

Yes, I use GNOME (ubuntu).
I have noticed that the keyboard seem to be "claimed" by one of the screens. So, if initially is claimed by the first screen, when I'm making the smplayer fullscreen, then the second screen claims the keyboard. Until then (until making the smplayer window fullscreen), even if the mouse is on the second screen and I click on a window on the second screen, any keyboard input is still sent to the first screen.

Another thing: the fullscreen thing doesn't work on totem player, but works with vlc and smplayer (that uses qt, so it is for KDE).
