I can confirm this bug is occurring on 11.04 Dell D6420 Intel Sandybridge Intel Video chipset. 
It seems to occur when you try to user multiple monitors.  Looks like it may be switching to 40 Hz refresh
rate even though xrandr reports it at 60 Hz.  Using the latest from edgers/ppa.  

There are also issues around configuration for multiscreen.  The laptop screen will stay black after reboot.
Using a Dell 1920 X 1080 monitor.    If there is more information I can provide, let know.
