my laptop does not hibernate or suspend?
 

i am using ubuntu 9.10 and when i close the lid of the laptop it does not hibernate or suspend?
what do i do?

You have to find the power management settings (somewhere in your menus).

For suspend to RAM*, you need your SWAP partition equal to the RAM size.

Also, I was having issues with recovery from suspend--in my case it was solved with an update to the official NVidia driver.


*"hibernate" means "suspend to disk"
