Hp compaq 6720 s laptop, VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c). kernel 2.6.32-25-generic

I have upgraded to Lucid Lynx from Karmic Koala, in power manager I have marked option on close the lid suspend laptop (general, battery, current adapter), but when close lid, laptop does not suspend. In karmic koala it worked (kernel 2.6.31-22)

I have to suspend laptop from xterm: sudo pm-suspend.

Where I can see to fix behaviour?, any script?, is it a kernel issue?

Thanks in advance
