You have a typo in your command line: use --debug instead of -debug.

Pastebin your /var/log/Xorg.8.log.

Have you tried changing DFP to CRT in /etc/bumblebee/xorg.conf.nvidia?

[amonakov]

With 304.64, it would make more sense to remove that line altogether (and optionally add "UseDisplayDevice" "none").

[amonakov]

In /etc/bumblebee/xorg.conf.nvidia, change "ConnectedMonitor" "DFP" to "UseDisplayDevice" "none".
