[arch-general] Mouse C&P not working

Hi folks another little glitch i use an "Logitech Marble Mouse" Trackball but since installing Arch i have been unable to get the C&P working at all well , the only way i can get anything like is to copy to the clipboard switch app then paste from clipboard . I am used to just grabing with the mouse and pasting straight to the relevent place without the un wanted extra steps i believe it need an mouse section in /etc/X11/xorg.conf.d but cant find any info on creating one any help please .. # Pete .
