I've been helping track down similar problems in the Hardy alpha 
releases. We have discovered that this is caused by poor power saving 
support, usually related to graphics card drivers.

The main workaround is to ensure that you don't use Standby or Hibernate 
modes when the lid closes. Instead, just use Blank Screen. You can set 
this from System menu - Preferences - Power Management.

This issue appears to be solved in Hardy for the closed-source Nvidia 
drivers. Unfortunately it has not been solved for the open-source Intel 


The irony of this bug being nailed fasted by Nvidia's closed-source 
team, than both Intel and the open source community can fix it with the 
open source software, is, I'm sure, not lost on any of us.
