How to rotate monitors vertically in Ubuntu 12.04

[bonuswhore]

Hello,

I currently have Ubuntu 12.04 running on 2x 24" monitors in landscape/horizontal mode, with 'Xinerama' enabled. I would like to rotate both monitors to be vertical. It is using an nvidia graphics card, and I'm using gnome-classic instead of Unity, if that matters

I'm trying to follow this guide:
http://www.libre-software.net/ubuntu-linux-external-monitor-nvidia-rotate

I've added the following line to both "Screen" sections in my /etc/X11/xorg.conf:
Option "RandRRotation" "True"

I also added the following line to both nvidia "Device" section :
Option "RandRRotation" "on"

then I rebooted, and when I tried to do rotate the screen with xrandr, I get an error:
$ xrandr -o left
RandR extension missing

anyone know what I'm missing here? I used to run Ubuntu 11.04, and I could easily rotate the screen by going to System-> Preferences-> Monitor and change the "rotation" drop-down menu, but I can't find that anywhere on my Ubuntu 12.04 installation.

Has anyone here been able to rotate their monitors vertically on Ubuntu 12.04?

[bonuswhore]

fixed it by changing Option "DPMS" to:
Option "Rotate" "left"

So I have 3 monitors - the middle and right are connected to one video card, and the leftmost is connected to its own video card.

I can have my center monitor landscape, and my right monitor vertical/portrait, and my left monitor landscape and everything works fine. If I switch the left-most monitor to vertical (via xorg.conf) it displays correctly in portrait but I can't move my mouse over there or drag any windows to the screen and I can't figure out why. Switch it back to landscape and it works, switch it vertically and I can't use it. any ideas?


-edit-
Also, I tried setting all 3 monitors to 'vertical' and then it locked me to only the middle monitor (monitor "0") and I couldn't move my mouse or drag windows to either the left or right monitors.

disabled and re-enabled Xinerama and this fixed it. Two video card, four monitors, two of them turned vertically.

here's the working xorg.conf if it can be of use to anyone:
