Public bug reported:

Curently using Ubuntu Karmic amd64, but preparing to upgrade to Lucid
shortly.

When connecting an external monitor to the analogue VGA port on the
laptop (Sony Vaio VGN-FE41Z) or the replicated port on the docking
station, the Nvidia driver adds a warning to the Xorg log:

(WW) NVIDIA(0): ACPI: Error: Unable to find the DOS (Enable/Disable output
(WW) NVIDIA(0):     switching) file path under /proc/acpi/video. The NVIDIA X
(WW) NVIDIA(0):     driver will not be able to respond to ACPI display change
(WW) NVIDIA(0):     hotkey events.

I noticed bug #339558 reported the same for the 180 driver but the
original reporter never followed up.
