I am running Ubuntu 12.04 on a Sony Vaio machine. System has ran Ubuntu for over 18months and never has this happened before. COnstantly keep update with all updates, however the last half dozen times i have put it into suspend (just shut lid) when i come to wake it up all i have is a totally black screen. No mouse cursor- just blackness!

Can anyone help please? Thanks
