MacBook air 3.1 ubuntu 12.04 won't suspend when closing lid, after installing nvidia driver

Question

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.

Thank's for reading and I hope i don't sound too noobish.

Answer 1

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.

Answer 2

I read in the link ( https://sites.google.com/site/easylinuxtipsproject/bugs#TOC-Hibernate-and-suspend-don-t-always-work-well:-they-make-some-computers-malfunction-or-even-enter-a-coma ) 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.
