suspend

Having a strange problem after upgrading from Ubuntu 11.04 to 12.04. Previously I could suspend just fine, the computer will switch itself off. Pressing the ON button will switch it on and it will resume.

After upgrading to 12.04 however, when I suspend it does (almost) the same, turns itself off, but about 2 seconds later, the computer turns itself on again, and it goes back to life from suspend.

I haven't changed any of the hardware or BIOS and it was working before just fine. Also tried every possible switch of pm-suspend ; setting acpi_sleep=nonvs in /etc/default/grub and also this suggestion but nothing seems to make a difference...

UPDATE: just tested suspend using the 12.04 liveCD and it was working perfectly fine... but when I boot normally it doesn't.

ANOTHER UPDATE: After re-installing I noticed that I can suspend. However, after restoring my home folder - the strange suspend problem happens again. I then created a new user account. When I login to the other account I can suspend without a problem... So This seems specific to my account only. How/What can cause this in my own user settings?

Why does my laptop resume immediately after suspend?

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I seem to be having some problem with suspend mode. Every time I try to suspend my laptop, it just locks the screen. Or maybe it successfully suspends just to resume only an instant after. What could cause such a behaviour? I'm running 32-bit Ubuntu 12.04 with the 3.2.0-25 kernel on a HP dv5-1178er… >>> More
