I've just bought a third monitor and additional the low-level graphics NVIDIA G210. (My onboard-card can only handle 2 monitors)
I set the "multi-monitoring" option in Bios and then tried the out-of-the-box solution with nouveau drivers. Ubuntu 14.10 managed it to make all displays work with correct resolutions. But the system was not really smooth anymore and the behavior was not as usual, so I installed NVIDIAs proprietary driver. The monitors in the graphics-card (HDMI + VGA) are working very well now, but the thrid monitor (onboard-graphic - DVI) - doesn't.

How can I reconfigure the i915 driver and make the third monitor work again?
Thanks for help!
//edit
The configuration before: intel: HDMI nvidia: DVI, VGA As I said, all monitors were working with this configuration, but the system was not smooth.
The configuration I prefer: intel: HDMI,VGA nvidia: DVI After experimenting with xorg.conf, crashing my whole system, repairing it again, reconfigure all drivers, the DVI with nvidia worked, while both of the others showed the logo.
Now I tried Bumblebee with these results:
The intel (hdmi+VGA) are working again. But the two monitors behave as one big, which is strange due to the fact that the VGA is in pivot mode. (I also have two cursors, when the cursor is at hdmi - one as usual - and one 90° inverted) Maybe someone knows a way how to fix this?
2nd problem: The nvidia is not working anymore. nvidia-settings are not able to detect the graphics card, although lspci -nnk | grep "VGA\|Display" -A2 shows

Why does the nvidia-driver does not appear here?
I also tried some configurations of bumblebee (add different nvidia drivers to /etc/bumblebee/bumblebee.conf Trying to make anything appear on the nvidia screen via optirun lets to
[ 2035.329815] [ERROR]The Bumblebee daemon has not been started yet or the socket path /var/run/bumblebee.socket was incorrect. [
2035.329865] [ERROR]Could not connect to bumblebee daemon - is it running?
So, more and more problems are growing, but nevertheless bumblebee might be the correct way solving my issues!?
//edit 2: Another problem: The consoles [ctrl][alt][F1-F6] are not working anymore. Maybe the reason is the default output on nvidia vga, which cannot be displayed. But debbuging Xorg without these consoles is not cool.
