Unsurprisingly, this problem remains in the latest ubuntu-x-swat nvidia driver, 280.13. There seems to be some kind of a fairly recent problem with nvidia backlight controls in the mactel community, with a few bugs filed (like #764195).

A comment mentioned some success adding the mactel PPA (ppa:mactel-support/ppa) and installing nvidia-bl-dkms:

 Thought it might be worth a shot, so I tried this on my Thinkpad W510 with Quadro FX 880M (based on GT 330M apparently), but backlight behaviour didn't change with the nvidia blob, even after reboot.
