Comment 68 for bug 34043

The acpi-support package is not involved in suspend/resume in recent versions of Ubuntu, and in any case making suspend/resume work appears to depend on a setting in xorg.conf - which acpi-support doesn't manage.

Reassigning to jockey, which is the package used for managing binary drivers in Ubuntu and can add this option to the xorg.conf by default for nvidia if that's the appropriate action.
