lid

It is happening now and then but frequently these days. My system E420 Lenovo Thinkpad running 12.04 LTS blacks out and doesn't respond when woke up from sleep by opening the lid.

I then have to forcibly press the Start button and restart the entire system which is creating a headache for me.

Please suggest a way to overcome this problem. Main characteristics leading to this that I have noticed are:

When a video is paused before I suspend the system
When Eclipse or pgAdmin is running before suspending the system

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.

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
