I've been unable to get multiple monitors to work with Ubuntu 13.10 using nvidia-prime or bumblebee. Could someone point me in the right direction?

With nvidia-prime, I've tried the xorg.conf here http://us.download.nvidia.com/XFree86/Linux-x86/319.12/README/randr14.html, but I boot into "low graphics" mode and have to revert to get a desktop back.

Any suggestions would be appreciated. Thanks.

Edit: I've given up on nvidia-prime; I missed the fact that it never turns off the discrete card... So, I'm back to trying to get VIRTUAL displays working with Bumblebee.

nvidia-prime

You do not need to play with xrandr, since it is already done for you in the nvidia-prime package (see /etc/lightdm/lightdm.conf).

The first thing to do is to comment the line Option "UseDisplayDevice" "none" in /etc/X11/xorg.conf. In my tests, it seemed you need to change modesetting driver to intel driver to get it work. I also had to add Option "ConstrainCursor" "no" option to let my mouse escape from the second screen.

Even after all those tweekings, my system was very unstable (when the screen freeze, I have to go back and forth to VTT1 (CTRL+ALT+1, CTRL+ALT+7), and window decorations were ugly.

Some insightful resources:

bumblebee

You no longer need hybrid-screenclone, nor to patch intel video driver. However, I'm not sure how to configure it.
