Second monitor doesn't display anything

view story

http://chakra-project.org – Hi everybody,I'm running on two monitors now, two Samsung, one 1680x1050 and the other 1280x1024. My 1680x1050 is running perfectly, but for some reason the other monitor is not being detected at all.If I go to System Settings -> Display & Monitor only my main monitor shows up and the "Multiple Monitors" Tab says: You do not appear to have a single  desktop spread across multiple monitors.That's what my xorg.conf says:[spoiler]Section "ServerLayout"    Identifier     "X.org Configured"    Screen    (HowTos)
