I recommend getting rid of xinerama. xrandr can handle multiple monitors just fine. If you are on KDE, try installing kde-base/kephal and use no xorg.conf. I still have the xinerama USE flag enabled globally as it adds multi-monitor awareness to some applications. With that, fullscreen applications work for me. Some still deactivate the second display or change the resolution but otherwise it works just fine. Regards, Florian Philipp
