Even my main monitor is shown as unknown. I have tried setting up dual monitors using Nvidia settings with no joy however it does recognize that I have 2 monitors.
This was not an issue in 11.04. My problem with the Nvidia settings appears to be that my 2 monitors require different resolutions but even when I set them to a resolution that they both can handle, it is then only appearing in cloned mode. I really hope someone can help or I will have to roll back to 11.04.
Why won't Ubuntu 11.10 recognize that I have 2 Monitors?
Here is the contents of my xorg.conf:

ok I have tried disper -e. Problem is that Nvidia settings appear to be treating both monitors as the same one. so changing the settings to one has no effect, but change the other and it affects both screens identically.
Results of disper -l as follows:

I solved this problem a few minutes ago on my system. For me it worked in the following way:
nvidia-settingsto configure my dual-screen, there you have to use the TwinView (not the seperate X-Config) and don't forget to choose a primary monitor. The problem I encountered during the config was, that I it only seems to work if I choose the left monitor as primary. To Test you can use the Apply-Button.Here my resulting xorg.conf if you want to read it:
When I solved the problem using Xinerama messed everything for me.
What I did was delete my xorg.conf file (after backing it up of course).
I then ran nvidia-xconfig and ran nvidia-settings. Got my second monitor recognized and used twinview, and then saved to my xconfig file.
Heres what my xorg.conf looks like:

I did just like tvn said, but I ran
then rebooted before setting anything up in
nvidia-settings.Xubuntu 12.04, GEforce GTX650, 2 x 24 inch 1920 x 1200 screens connected by DVI-D both run in portrait mode.
None of the Ubuntu Software Center nvidia drivers would rotate screens. The current driver is ver 304.88.
Downloaded: NVIDIA-Linux-x86_64-319.23.run from: http://www.nvidia.com/Download/index.aspx?lang=en-us
then: Ctrl-Alt-F1 - full screen terminal mode
After installation:
logon and open a terminal window (Windows - T)
Or the same program from the menu: Settings / NVIDIA X Server Settings
The latest nvidia drivers include screen rotation in the X Server Display Configuration screen. The ubuntu Settings / Settings Manager / Display will still not run, but is not needed.
Enable Xinerama - all working sweetly.
