Yesterday, I installed Ubuntu 12.04 Desktop i386 on my netbook (HP Mini 311c).
I am unable to use the sleep mode. When I press the suspend button (or do sudo pm-suspend), the screen flickers but the computer does not power off. Even worse, the screen comes back up and I'm back where I left off.
Hibernating does work (although it is not available in Power Management). I have to use pm-hibernate to make that work.
I'm using the 3.2.0.20 kernel and Gnome 3.3.92 (Unity, especially compiz, is a resource hog).
Before Ubuntu 12.04, I was using Mint Linux 12 with the 3.0 kernel and everything worked fine back then. Any help is much appreciated because this is driving me crazy.
