I can't get my second monitor to work. It's detected but black. A screenshot captures both desktops. They work fine in Windows. I want to span the desktop, I tried a 'new screen config' in Nvidia panel and then enabling Xinerama but it didn't do anything. I also couldn't find an option for TwinView. I can get the other (right) monitor working if I set that as default and switch monitors on/off but then left monitor is black.
