Bug or configuration problem?

[Alyssa and Chris Gordon & Family]

I recently installed ubuntu.  It has all worked perfectly from the start 
with one exception.  When my monitor sleeps then wakes up, the screen 
'flickers' pretty much constantly until it restarts.  Do I need to 
somehow reconfigure my monitor, or is this something I should submit as 
a bug.  I searched google and can't find anywhere else where someone has 
had this problem.

Thanks

Chris
