For the past few weeks, when opening the lid my laptop often fails to recover from suspension leaving me with a blank screen.  Further, when this bug occurs, the laptop fans continue to run while the lid is closed, causing my laptop to quickly overheat in my bag. I have read various different questions on here that had similar symptoms but none of the solutions worked in my case.  Disabling suspension on gnome seemed to reduce the frequency of this issue, but it still occurs with some frequency.  It only seems to occur if I do not lock the computer before closing the lid or I am in a different desktop manager (such as dwm).  I currently have the ATI graphics drivers enabled (not sure on the specific driver, but it is whatever driver that Jockey installed).
