Debian Jessie black screen after suspend

Hi, I run a macbook 13'' with Debian Jessie (8). I am able to hibernate 
and resume but I'm not able to resume from suspend. When I try to 
suspend both from gui than from terminal (pm-suspend or systemctl 
suspend) I get only a black screen on resume. The computer works but it 
seems that the brightness is set to zero and I can not turn it on.

This is my graphyc card:

-----
:~$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 
Integrated Graphics Controller (primary) (rev 03)

This is the log:

If necessary I also get the log from journalctl.

I google a lot but I haven't found a solution.

Do you have any suggestion to solve this annoying issue?

All the best, Ricca
