The fglrx proprietary driver supports XRandR 1.2, so the Displays
capplet will (should) work for it.

The nvidia binary driver does *not* support XRandR 1.2, so (as Daniel
notes) the Displays capplet will not work properly (specifically, it
won't do any multihead or external display setup) with the nvidia binary
driver.

Title:
  Displays utility doesn't offer to use nvidia-settings with proprietary
  drivers installed?

Bug description:
  On this system, the proprietary nvidia drivers are required for some
  features (like suspend/resume) to work correctly. On previous Ubuntu
  versions, opening the "Monitors" control panel detected the
  proprietary drivers and offered to use nvidia-settings instead of
  Displays. This is required, for instance, to be able to properly
  detect screens and enable the VGA, DisplayPort and HDMI video outputs
  which are completely ignored by g-c-c's Displays applet.

  However on 11.10, Displays doesn't have this behavior, so the user is
  left to figure out why DIsplays is so limited and unable to
  detect/enable external screens, and eventually to learn to use nvidia-
  settings from a command prompt. This is quite confusing for novice
  users.

  I'll attach some files with hardware information, this machine is
  primarily used for testing so please don't hesitate to let me know if
  I can provide more detailed info or run any necessary tests.
