Running Ubuntu 12.04 64 bit. Gnome Shell as interface. Graphics card of nVidia GT555M. Drivers - Bumblebee and not nVidia's. Can get great VGA support (which is also on card) and optimal screen res. Optirun works and gives good outputs (125~ frames/sec && 172~ Mpx/sec). No xorg.conf. Tried getting HDMI output with xrandr but still do not work. Ideas?

x@x:~$ dpkg-query -l | grep bumb
ii  bumblebee                                                   3.1-1~preciseppa1                             nVidia Optimus support
ii  bumblebee-nvidia                                            3.1-1~preciseppa1                             nVidia Optimus support using the proprietary NVIDIA driver

Can anyone help me to get HDMI output working? Even while connected to HDMI, screen can get current and indicate that it is connected to a card, but xrandr gives:

Screen 0: minimum 320 x 200, current 3040 x 900, maximum 8192 x 8192

disper did not help and gave me this:

x@x:~$ disper -l
display LVDS1: LVDS1
 resolutions: 640x480, 800x600, 1024x768, 1152x864, 1360x768, 1440x900, 1600x900
display VGA1: VGA1
 resolutions: 640x480, 848x480, 800x600, 1024x768, 1440x900

Thank you very much for your help.

People seem to say that this method works. It involves using a separate (non Unity) session for the secondary monitor.
