Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

Installation method:

  • Downloaded 11.10 iso and installed to USB stick with no persistent area,
  • Ran Ubuntu from the USB stick to check hardware compatability,
  • Used the desktop icon to run installer from within running Ubuntu,
  • Checked the box to download updates while installing,
  • Checked the box to allow 3rd party stuff while installing.

Hardware (see end of post), i7, GeForce GFX 560 Ti.

Launching from USB, Ubuntu detected both monitors and I was able to use "Displays" to configure my monitors. However, I noted that it was running in "standard" experience (unity2d). Both monitors were correctly identified by "Displays".

After booting the new install from HD, only one monitor is detected. nVidia drivers were already enabled from within Jockey. Using sudo nvidia-settings, after much experimentation I was able to get both displays working by using "TwinView" (which seems wrong).

Displays shows a single 3200x1080 display of "Unknown", "Detect Displays" does nothing,

System Info shows "Graphics Unknown" and "Experience Standard"

Is there some way to get it to behave the same way that the "Live" Ubuntu ran (correctly detecting two monitors and allowing me to configure them directly without going thru the control panel) and is there a way to get Unity 3D to run on this card?

I think you need to remove the third party drivers. I had the same issue and have seen other posts on the forum as well.

Can you link to those posts on the forum? –  jrg Dec 30 '11 at 14:04
    
Deactivated nVidia drivers in jockey, still no joy: Displays still only sees one "unknown" display and jockey seems to think there is a different version of the second driver installed. –  kfsone Jan 2 '12 at 23:18
