Please see https://bugs.edge.launchpad.net/ubuntu/+source/gnome-control-center/+bug/215396 The xrandr code doesn't check for a NULL return from rw_screen_new, and so falls over. The message returned here could be tweaked, we reused one to not break string freeze, but it appears Fedora doesn't use l10n here, so that might not be a consideration for you. Thanks, James
