I did a fresh install of Ubuntu 14.04.
Everything works great except after hibernate/suspend I am getting a black screen.
I can use `Alt`+`Ctr`+`F1` then `Ctrl`+`Alt`+`Del` to restart and the screen comes back fine.

I am using the open-source `X.org X-server` drivers.

My laptop is hp pavilion g6, APU A8-3520M with Radeon HD 6620G

What can I do to make screen come back after suspend/hibernation?
I've checked some old thread from 2010 where people add a little piece of code to somewhere in the system to force the screen come back or something.
