Public bug reported: I just installed the nvidia-current driver through jockey. Upon reboot, only 1 display was detected by Xorg/nvidia driver. The other display remained in standby.
I had to start nvidia-settings and configure the second display in "TwinView" configuration and save the result to /etc/X11/xorg.conf before it all worked.
