I've seen this happen when the proprietary nvidia drivers are installed on the server, and the clients have intel graphics cards. I think the nvidia drivers install their own versions of the opengl libs, and that somehow messes with xrandr etc.
Please do an lspci -nn on both the server and the clients, and also specify if you use any proprietary drivers.
One way around it that worked for some people was to disable compiz (System > Preferences > Appearance > Visual Effects: None - or something like that, I got localized menus). But that's a per-user settings, kind of difficult to do that for all users.
You could also try to put XRANDR_REFLECT_0 = y in your lts.conf.
But if the proprietary drivers are indeed the problem, then probably the best way would be to uninstall them, and restore the original opengl libs...
