Dual External Monitors on a Dell E4260 in Ubuntu 11.10

I basically wanted to replace my desktop at work with the laptop that they gave me. I might get to telecommute sometimes. Anyway, the desktop at work had two nice big monitors and I wanted to use these with the laptop, through the dell docking station. This is one of those things that I think should be easy but was not for me. Mostly because I look the wrong place for the solution at first. 
The laptop has a nVidia 4200m video card with optimus. I installed ubuntu as normal, then I installed the current nVidia driver sudo apt-get install nvidia-current, rebooted the computer. went to the console and typed nvidia-settings. I got this error message “You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server.” So like a lamb to the slaughter I did just what it said. Unfortunately when I rebooted the computer I just got a blank screen. 
I rebooted the computer in recovery mode, deleted the /etc/X11/xorg.conf file and rebooted the computer. It started normally again. I did some more research and found that the bumblebee driver is supposed to work with the optimus nVidia cards I installed it, the system started up fine, but I still was not able to detect all 3 monitors. After some more research I found here that all I needed to do was disable the optimus feature from the bios. 
So I disabled the optimus in the bios rebooted the computer, reinstalled the nVidia driver all then I was able to run nvidia-setting and see all 3 monitors, but I only configured the two external on twin-view. I might update this later after I figure out how to have just the laptop monitors as primary when the  other 2 are not connect and the one of the externals as primary when the monitors are connected. I am not sure how much effort I will put into this as I hear that the next version of Ubuntu will have more support for this kind of thing.

      Windows e8 meglio perche8 e8 madulore come hardware e software.Le cosole sono fisse, potenza cpu, schede video medie risoluzione e fps standard, da li non si scappa.Con un pc con windows puoi madulore a seconda dei soldi e delle esigenze, cpu 1,2,4,6,8 core, ram, schede video 1,2,4 + fisica, e giocare a risoluzioni e dettagli oltre che fisica delle particelle, che su una console attuale te li sogni. Inoltre tutta questa marea di hardware e software connessi (esempio Hardware Tessellation, physx multi monitor, 3d eccetera) sono tutti disponibili sotto windows, cosa che non avviene per altre piattaforme.Inutile sostenere la maggior potenza delle console, un i7 con un quad-sli potente, le console le svernicia e gli da due mani di antiruggine (ovviamente ad un costo nettamente superiore), ma qui parliamo della potenza massima della piattaforma wintel, non di costi.provate a giocare a flyght simulator massimi dettagli su 3 monitor 22 fullHD, e poi usate una console, piangerete per 3 giorni Poi certo, anche Pong e8 divertente volendo
