Open for edit the /etc/grub/default file with:

gksudo gedit /etc/default/grub

Locate the value:


and change to:

GRUB_CMDLINE_LINUX="acpi_osi=Linux acpi_backlight=vendor"

Seems to have worked. It had a side benefit. I was having an opposite effect with the dimming when inactive. The display was very bright when inactive, but dimmed as soon as I touched the touchpad. This seems to have been fixed as well. And for what it's worth, I left the "quiet" argument in as well. Doesn't seem to have made a difference. Thanks a bunch! – Dana Nov 22 '12 at 17:41
