Closing lid freezes laptop ubuntu 10.04
Hi,
Everytime I close my laptop lid, my laptop doesn't go into hibernate,suspand,blackscreen... It just freezes, even when I open the lid, and the only thing left to do is restart my pc. I use a dualboot system, vista 64 and ubuntu 10.04 on a Dell Studio 15. Is there any way to fix this without messing up the vista partition?
