I just installed Ubuntu 12.04 on my MacBook air I had a small graphic problem described here: Recent LCD trouble with 12.04 on 2010 Macbook Air 11 (3,1). So I followed the answer and installed the latest Nvidia driver, but now my air won't suspend when closing lid, but it does work if I suspend manually.

I use XFCE, and here's how I fixed the problem: in settings / power manager, associate "suspend" with "closing the lid" for both AC and battery. It seems to work fine.

I read in the link ( ) that it's a known issue. The author of the page reckons that "Suspend" be turned off. I am not sure whether a fix is available for this known issue.
