Yes, the backlight is the only thing that doesn't work so well. I can control the backlight - I think I had to tweak some setting that I found on Google, but I don't remember which - but its auto-darkening on inactivity is pretty broken. When I move the mouse or type a key, the screen brightens again, but only about halfway back to what it was before the auto-darken, so I then have to manually jack the brightness up each time this happens.

Hoping some new driver release will fix this some time, but it's only a minor irritation.

BTW, your link [1] seems to be broken?

I love the trackpoint. I've disabled my touchpad completely.

Yes, the forums' website is down. Here is the google cache [2]. The link [1] entitled "NVIDIA Quadro NVS 3100M on Lenovo Thinkpad T510: NVIDIA Backlight Control Causes Buzz" is the first result in the search for "t510 backlight" [3].

The issue has also made it to Canonical's launchpad [4]. The link [1] is mentioned in comment #27 [5].
