suspend

I'm running Ubuntu version 12.04 on Dell D620 laptop and have been for months. Everything has been working fine until a week ago, when suddenly every time I close the laptop and open it again, the program in use blinks each time I make a keystroke. Only the program blinks, not the whole screen. Rebooting solves the issue until I close the lid again. I have installed all the updates recommended in the package manager.

Clues?

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?

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
