I will run the tests with the latest build over the weekend and post the
results.

Some additional information, if I switch to nvidia proprietary driver the issue does not reproduce. 
Also if I shutdown X (lightgdm stop) the suspend function works as expected.

Title:
  Xorg freeze / System Freeze after suspend

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Problem is related to suspend, regardless if the lid of the laptop is closed or  "Suspend" from the menu is pressed. 
  At resume, the screen is displayed and only the mouse can move for 10-15 seconds then everything freezes.  
  One time I managed to switch to terminal mode and issue a lightgdm restart: The login window appeared but after the correct username/password was provided it was enable to start the session and the login prompt appeared  again.     
  So far I have tried playing with boot parameters: 
  pcie_aspm=force (no change) 
  nomodeset (it makes the problem worst the screen is black, not even the backlight seems to be on) 

  Also I have tried running from : https://wiki.ubuntu.com/KernelTeam/SuspendResumeTesting
  wget http://people.ubuntu.com/~apw/suspend-resume/test-suspend
  sudo bash test-suspend --full
  Test1 is not able to suspend the machine, 
  test 2 does suspend it but it does not wake up automatically after 20 seconds. And when I press a key to wake it up... it freezes. 

  The issue does not reproduce on the same hardware with LMDE MATE Edition, Proprietary nvidia drivers, 
  Linux 3.10-2-amd64 (x86_64), Compiled #1 SMP Debian 3.10.5-1 (2013-08-07).

  Any other information I could provide?
